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.
