title = "Multiple-beam planar lens antenna prototype",
abstract = "A new low-height X/Ku-band (8.2-12.2 GHz) antenna was designed, built and tested which provides full 360 degree coverage around azimuth using multiple beams, covering the low elevation angles with peak gain of 12 dBi at 10 GHz. Computer modeling showed that about 18 dBi gain can also be achieved using this type of lens. The antenna shape is circular and flat with feed ports in a circle near the periphery. Switching between beams is accomplished by switching between beam ports. The prototype antenna built was 13.3 cm diameter by 1.56 cm high, which is approximately 4 1/2 wavelengths wide by 1/2 wavelengths thick at 10 GHz. The weight was 259g. Each feed port drives a small monocone to feed the lens, which radiates a beam close to endfire on the opposite side from the driven feed port. This flat lens antenna is extremely wideband and radiates a leaky wave from the surface of the beamforming lens, so it combines the functions of beamformer and planar radiating aperture into one structure, thereby achieving lower height and weight and simpler construction than other antenna types with 360° coverage.",
