Abstract
An aperture-coupled patch array antenna with a reduced sidelobe level (SLL) at the 28 GHz frequency band is presented. The feeding line consists of an asymmetric stripline with a stripline-to-waveguide transition. The array antenna is serially fed in the E-plane, the excitation of which is tapered by controlling the aperture sizes, and is fed through a power divider in the H-plane. The experimental results show a SLL of <;-20 dB and a gain of ~20 dBi for a frequency band in the range of 27.5-28.5 GHz.
