Dual-Polarized Wideband Low Sidelobe Slot Array Antenna for V-Band Wireless Communications

A dual-polarized wideband low sidelobe slot array antenna for wireless communication systems in the V-band is proposed this work. Taylor distribution applied with each radiating as a tapering unit both polarizations. compact 2 × elements subarray designed to achieve stable amplitude and phase among two sets of integrated unequal power dividers E- H-planes inside subarray. Then, layers orthogonally polarized feeding networks E-plane T-junction are used connect subarrays standard waveguides WR-15 input ports. The prototype 8 fabricated measured an anechoic chamber. maximum gain 25.3 dBi 25.4 V- H-polarization, respectively. overlapped impedance bandwidth from 57 66.4 GHz reflection coefficiencies below -10 dB, isolation between ports around 35 dB. Sidelobe levels polarizations -22 dB good agreement simulations.
