The document discusses different types of antennas used in wireless communication. It describes antennas such as dipole antennas, horn antennas, parabolic dish antennas, and antenna arrays. Dipole antennas are simple and widely used. They consist of two conductive elements that transmit and receive electromagnetic waves. Horn antennas guide radio waves into a beam but have limited directivity. Parabolic dish antennas have high gain and directivity due to their distinctive parabolic shape. Antenna arrays combine the radiation patterns of individual antenna elements to provide benefits such as high gain and directivity.

Antennas convert electrical energy to radio waves and vice versa. Microwave frequencies range from 1 GHz to 1000 GHz. Common antenna types include monopole, dipole, parabolic, Yagi, and microstrip. Antenna performance is characterized by properties like radiation pattern, directivity, gain, impedance, efficiency, polarization, bandwidth, and noise temperature. Microstrip patch antennas are low profile, lightweight, inexpensive to manufacture and compatible with microwave integrated circuits. They have a conducting patch on a dielectric substrate mounted over a ground plane.

https://app.box.com/s/tacvl9ekroe9hqupdnjruiypvm9rdaneLAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

- 3. ANTENNA ⚫An antenna is an electrical device which converts electric energy into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. ⚫An antenna is a device for sending or receiving electromagnetic waves.
- 4. TRANSMITTER ANTENNA A device that converts sound, light, or electrical signals into radio, microwave, or other electrical signals .
- 5. RECIVERANTENNA An antenna used to convert electromagnetic waves in to electrical energy.
- 6. TYPES OF ANTENNA ⚫YAGI – UDA ANTENNA ⚫LOG – PERIODICANTENNA ⚫HELIXANTENNA ⚫PARABOLIC ANTENNA ⚫LOOPANTENNA
- 7. YAGI – UDAANTENNA ⚫Yagi-Uda antenna consist of reflector, director and driven element. ⚫It is unidirectional antenna. ⚫Frequency range – 300MHz-3GHz
- 8. Seven element Yagi – Uda
- 9. Yagi – Uda advantage ⚫High gain and good front to back ratio. ⚫It has narrow bandwidth. ⚫It is fixed frequency device. ⚫Grater directivity due to director and reflector.
- 10. Log - periodic antenna ⚫A unidirectional antenna in which the length and spacing of the elements increase logarithmically from one end to the other. ⚫It is frequency-independent antenna. ⚫Frequency range – VHF and UHF band.
- 11. Log – Periodic Antenna
- 12. Advantages ⚫It is broadband antenna. ⚫It is unidirectional antenna. ⚫It is frequency independent antenna.
- 13. HELIX ANTENNA ⚫Aconducting wire in the form of screw thread fed by power source. ⚫The feed line is connected between the bottom of the helix and the ground plane. ⚫Helix antenna is Omni directional. ⚫Frequency range – VHF and UHF band.
- 14. Helix Antenna
- 15. Application ⚫Satellite communication. ⚫Space communication & space probes. ⚫For telemetry applications.
- 16. PARABOLIC REFLECTOR ANTENNA ⚫This is used to convert spherical wave into plane wave ⚫The feed antenna is called primary antenna and reflector is secondary antenna. ⚫Frequency range - 3GHz-30GHz
- 19. LOOP ANTENNA ⚫Adirectional-type antenna consisting of one or more complete turns of a conductor. ⚫It determine the direction of arrival of radio signals. ⚫Frequency range – 500-1600KHz.
- 20. Loop Antenna
- 21. Application ⚫Direction finding of signal propagation. ⚫Radio(AM/FM)reception. ⚫Long distance point to point communication.
- 22. Antenna Arrays ⚫Arraysare used to increase diretivityand gain in desired direction. ⚫Eliminate the radiation in undesired direction.
- 23. Broadside Array ⚫If thedirectionof maximum radiation is generated is perpendicular is called broadsidearray. ⚫Each antenna is fed by thecurrentof same magnitude and phase. ⚫Radiation pattern is bidirectional.
- 24. Broad side array
- 25. End Fire Array ⚫If the maximum radiation is generated parallel to the antennaarray axis is called end fire array. ⚫Each antenna is fed by thecurrentsame magnitude and opposite phase. ⚫Radiation pattern is bidirectional.
- 26. End fire array
- 27. CONCLUSION ⚫All theantennaarevery useful in all theapplication such as transmitterand receiver. ⚫Antennaare used toconvertelectrical energy to electromagneticenergy.
