Abstract
A metasurface antenna is proposed for the dual-band operation in 5G millimeter systems. The metasurface consists of a single-layered square patch array excited by two microstrip feeding slots cut onto the bottom ground. The characteristic mode analysis is used to optimize the metasurface patterns for the dual-band operation. The modes of metasurface resonant at 30 GHz, 38 GHz, and 41 GHz, respectively. To broaden the bandwidth, the etched slots on the ground are resonant as well. The impedance is matched over the frequency ranges of 23.75–28.8 GHz and 36.22–40.5 GHz with return loss larger than 10 dB. The simulated gain reaches 8.8–10.17 dBi and 9.46–12.6 dBi over the operating bands, respectively.
