Antennas in practice - EM fundamentals and antenna selection
This book “Antennas in Practice” has been in existence in a multitude of forms since about 1989. It has been run as a Continuing Engineering Education (CEE) course only sporadically in those years.
It has been revamped on several occasions, mainly reflecting changing typesetting and graphics capabilities, but this (more formal) incarnation represents a total re-evaluation, re-design and re-implementation. Much (older) material has been excised, and a lot of new material has been researched and included.
Wireless technology has really moved out of the esoteric and into the commonplace arena. Technologies like HiperLAN, Bluetooth, WAP, etc are well known by the layman and are promising easy, wireless “connectivity” at ever increasing rates. Reality is a little different and is dependent on a practical understanding of the antenna issues involved in these emerging technologies.
Although a fair amount of background theory is covered, its goal is to provide a framework for understanding practical antennas that are useful. Many design issues are covered, but in many cases, the “cookbook” designs offered in this book are good-enough starting points, but still nonoptimal designs, only achievable by simulation, and testing.
As a result, the book places a fair amount of emphasis on antenna simulation software, such as SuperNEC. Ordinarily, if this book is run as a CEE course, it is accompanied by a SuperNEC SimulationWorkshop, a hands-on introduction to SuperNEC. It is only through “playing” with simulation software that a gut feel is attained for many of the issues at stake in antenna design.

Antenna parameters part 3 - Input impedance and VSWR
VSWR stands for Voltage Standing Wave Ratio, and is also referred to as Standing Wave Ratio (SWR)The input impedance of an antenna per se is not usually reported directly in the brochure; rather the antenna’s nominal impedance and its VSWR are given. The nominal impedance is the impedance for which the antenna is (ideally) designed and the VSWR can be “seen” as the antenna’s deviation from this value.
The VSWR (voltage standing wave ratio) is a parameter that is derived from the antenna’s input impedance and the reported nominal impedance. One can view the VSWR as “how far” the antennas input impedance is from the nominal impedance. If the VSWR at a particular frequency is given as 1:1, then you can deduce that the antenna input impedance is equal to the nominal impedance. The higher the VSWR the further the antenna input impedance is from the nominal impedance.
Antenna parameters part 2 - Polarisation
The polarisation specification for an antenna specifies how the electric field behaves in the far field (where the radiated wave has established itself).
Antenna parameters part 1: Frequency bands, Gain and Radiation Pattern
This is part of an internal document that that gives an overview of the properties of antennas for non-engineers.
We have divided the document into different posts where we discus each of the parameters:
Frequency bands, gain and radiation pattern
Polarisation
Input Impedance and VSWR
Port to port Isolation and Cross-polarisation
Power Handling ability
Antenna “Specmanship”
Where applicable we have added some videos explaining the properties discussed.

Fixed Broadband Business Case - Short Version
1) Using external directional antennas on customer premises equipment can increase data speeds by 3-5 times compared to indoor antennas, allowing operators to serve more customers per cell.
2) This is because outdoor antennas have higher gain and operate in a channel environment more conducive to high data rates compared to indoor antennas.
3) Financial modeling shows that equipping customers with outdoor antennas can reduce capital expenditures by 66% while increasing revenue by 200% per cell after accounting for the cost of the antennas and installation.
Role antennas play in a MIMO link - paper
- MIMO technology uses multiple antennas at both the transmitter and receiver to increase wireless network throughput. The performance of a MIMO link depends directly on the antennas' radiation patterns and polarizations.
- Outdoor wireless channels provide much better throughput than indoor channels due to less signal interference and reflection. Using outdoor antennas is emphasized whenever possible.
- For MIMO to work effectively, the signals received by each antenna must be sufficiently uncorrelated. Antenna polarization and positioning can help create independent transmission paths and improve throughput.
The role antennas play in a MIMO link
The document discusses the role of antennas in MIMO (Multiple Input Multiple Output) wireless communication links. It covers topics such as:
- Where MIMO is used, including Wi-Fi, WiMAX, and LTE wireless technologies.
- The concept of SDMA (Spatial Division Multiple Access), which allows multiple data streams to be sent over the same frequency resource using antenna radiation patterns and polarization.
- Factors that affect wireless channels such as indoor vs outdoor environments, single vs multiple signal reflections, and their impact on signal strength and performance.
- How MIMO works by exploiting spatial diversity and multiplexing gains using multiple antennas at both the transmitter and receiver to improve data rates and link reliability.

Powerful business model for fixed wireless data using outdoor antennas - Paper
Paper presented at the 2nd Africa Radio Comms Conference in Johannesburg - Nov 2015
By Andre Fourie
The revenue that can be generated by an LTE base station is influenced by the quality of the signal received by the customer premise equipment (CPE). Most CPE come with omni-directional indoor antennas, but have provision for the connection to external antennas.
Substituting the indoor antennas for directional outdoor antennas has a marked effect on the data transfer speeds of the network. There are two reasons for this. Firstly, outdoor antennas are physically larger than their indoor counterparts and thus have a higher gain. The increase in antenna gain translates directly to an increase in received signal strength. The second advantage is that the outdoor antenna sits in an environment that has much better propagating properties than the indoor antenna. Tests have shown that data speeds 3-5 times faster are possible using external antennas compared to indoor antennas.
It is shown, using a primitive financial model that fairly large financial gains can be made by equipping CPE devices with external antennas.
Business case for fixed wireless 4G/LTE using outdoor antennas
LTE/4G networks business plans involve capex spend on radio access infrastructure to meet business objectives ito customer offerings ito bandwidth, data rates, bulk data and QoS. Assigning some Capex to CPE equipment with outdoor antennas can reduce Capex significantly for same capacity and considerably better reliability and QOS

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.
