A Study on Thinner Lens Antenna with High Dielectric Constant and　Antireflection Coatings Considering NTN

Beyond 5G/6G systems aim to expand coverage to ground, sea, air, remote areas, and space. Its non-terrestrial network (NTN) is being developed. NTN utilizes mmW for high-speed, large-capacity, and low-latency communication, but requires high-gain antennas to compensate for high propagation loss. This paper introduces lens antennas with anti reflection coationg as high-gain antennas for NTN.
