摘要: A highly performing dual-band and broad-band planar antenna can replace conventional feed horn technology as feed antennas for reflector systems. Embodiments allow custom electronically selectable polarization: linear or circular polarization in both bands independently by controlling the amplitude and phase stimulation of four feed probes for each band. Full integration of the antenna and RF frontend can be on the same printed circuit board or chip. Embodiments alleviate the need for specialized polarizers and orthomode transducers for operation in circular polarization and two bands. The planar antenna has low footprint and weight as compared to traditional horn antennas and facilitates greater flexibility in design and can be produced with standard low-cost PCB production processes and materials. Performance comparable to traditional horn technology can be achieved, such as extremely rotationallv symmetric beam thus suitable for efficient reflector illumination together with extremely low cross polarization performance.

摘要: A multi-antenna device may include a high-frequency antenna, a lowfrequency antenna, and a patterned metal ground plane defining channels having capacitors operable a short circuit for the high-frequency antenna and an opencircuit for the low-frequency antenna. The high-frequency antenna, the lowfrequency antenna, and the patterned metal ground plane may be coupled to a multilayer printed circuit board of the multi-antenna device. The channels of the metal ground plane conductor may have dimensions to, themselves, operate as the capacitors. In other aspects, discrete capacitors may be positioned on the metal ground plane proximate to the channels to reduce eddy currents during operation of the low-frequency antenna.
