Broadband Connected Slots Phased Array Feeding a High Gain Lens Antenna at 60 GHz

This paper presents a 60 GHz connected slots linear phased array feeding a high gain semi-symmetric lens antenna. This novel design provides high gain, broadband and beam-steering capabilities for gigabits rate access and backhaul communications. The 16× connected slots are fed periodically to allow ± 45 ° beam-steering in the H-plane. The results show more than 33% impedance bandwidth, 24.6 dBi maximum gain and 3 dB gain bandwidth covering the full band 57-66 GHz. Besides, the half power beamwidth (HPBW) is 6° and 10° in E-and H-plane, respectively.
