Abstract:
This paper proposes a high gain grid array antenna (GAA) with enhanced bandwidth for 5G base station applications. The wideband GAA characteristics is achieved by loading the rhombus patch on the short radiating sides of the conventional GAA. By loading the rhombus on the short radiating sides of the conventional GAA, the additional capacitive reactance is introduced to cancel out the inductive reactance which leads to the enhancement on the bandwidth performance. The amplitude-tapering is applied to reduce the side-lobes levels of the grid array antenna. From the simulated results, it can be observed that the proposed GAA manages to support a -10 dB impedance bandwidth of 16.07% which is ranging from 27.5 GHz to 32 GHz with maximum achieved gain of 14.8 dBi. The overall dimension of the proposed wideband GAA is 25 × 25 × 0.787 mm3.
