A Ka-band phased array of antennas with parallel-plate parabolic reflector feeding network for high energy-efficient radiation

The paper presents a Ka-band phased array of antennas with a beamforming network (BFN) realized by using parallel-plate parabolic reflector cavity. The BFN is realized in the substrate integrated waveguide (SIW) formed cavity with a point-excitation to form a space-fed configuration. In addition, th...

Summary:The paper presents a Ka-band phased array of antennas with a beamforming network (BFN) realized by using parallel-plate parabolic reflector cavity. The BFN is realized in the substrate integrated waveguide (SIW) formed cavity with a point-excitation to form a space-fed configuration. In addition, the corrugation structure on sidewalls of the two input reflecting surfaces is constructed to disturb the cavity resonance and mitigate multi-path interferences as the waveguide propagation to create the required phases for antenna excitations. The proposed BFN is used to excite an 8 × 10 antenna array at top layer of the standard PCB to demonstrate the characteristics of low loss and high directivity. The measured results show the 20.8 dB of gain and 23.45 dB of directivity at 38 GHz.
