7. 7© Copyright Plasma Antennas Ltd 2015
• Lower Cost and Complexity
– Relative to alternative solutions of similar performance
• Lightweight, Compact and Reliable,
– No moving parts and highly integrated beam selection and beam forming
• Wide Instantaneous Bandwidth
– Time delay steered operation (not phase shifted) for wideband pencil beam operation
• Wide Frequency Coverage
– Technology applicable to bands within the 1GHz to 100GHz+ range
• Wide Electronically Steered Azimuth and Elevation Coverage
– Number and shape of directed beams can be tailored to meet specific system requirements
Typical Benefits
• Fast Beam Switching
– Possible within inter-packet/inter-pulse periods
• Adaptive Beam Shaping and Nulling
– Allows optimised beam footprints and maximization of SINR
• High CW RF Power Handling
– Operation with commercially available radio and radar front-ends
• Reciprocal Tx/Rx Operation
– Allows precise alignment of Tx and Rx beams without calibration (important in many civil and
military applications)
• Omni and Floodlight Beams
– Enables one to many broadcast modes to allow beam scheduling and synchronisation

Disruptive Features of Multi-beam
Antennas
• Unlike phased arrays most do not use Tx/Rx amplifiers
• Very low loss, highly linear switches with good power handling
• State-of-the-art azimuth/elevation beam-formers
• Time-delay steered and have wide instantaneous bandwidth
• Both FDD and TDD operation
• Replace fixed beam with higher gain electronically directed antennas
• Retain omni and floodlight beams for acquisition and broadcast
• Cylindrical antennas are lower gain and dual polar with 360 degree coverage
• Planar antennas are higher gain and dual polar with 120 degree coverage
The Plasma device technology, at a demonstrator level provides
– greater power handling
– many more beams (100s maybe 1000s)
– operate at higher frequencies
– cost less in high volumes
……it is a highly credible way forward for 5G and other wireless applications (e.g.
backhaul and ITS).
