Dual-polarized Fixed-frequency Beam Scanning Leaky-wave Antenna for 5G Communication

摘要

- A low profile and dual-polarized fixedfrequency beam scanning leaky wave antenna for 5G communication is presented, which is based on a corrugated microstrip line (CML) called spoof surface plasmons transmission line. The antenna radiates horizontally polarized electromagnetic wave and vertically polarized electromagnetic wave using two different periodic antennas elements. The fabricated antenna is measured and the results show that the operating frequency of the antenna is 3.4-3.7 GHz. The measured main beam angle scans from -9 degrees to -30 degrees. The measured gain is from 8.3 dB to 9.7 dB over the working band.
