Design of Holographic Beamforming Antenna with Slot-Shaped

Abstract

The future sixth generation (6G) wireless communications expected to construct intelligent network with low-power and high-throughput transmissions. To fulfill such challenging visions in this paper we design Holographic beamforming (HBF) antenna which is developing into a promising solution due to its flexible beamforming capability with lower energy and hardware costs. The HPF consists of an aperture-shaped microwave length array on the metasurfaces (meta-elements) that is different from the conventional phase-controlled antennas. The HPF can control the radiation amplitude and phase of reference wave propagation on the metasurface by leveraging the holographic technique. The PIN diode used in each slot to dynamically tuned between the "on" and "off" states to control the radiation direction. The proposed antenna dimensions are 50mm x 50mm. The substrate used (Rogers 4003, p = 3.38 and tan = 0.0027) and 0.578 mm thick. The feed line coaxial cable in corner to antenna is used to control the air conditioning. The HPF antenna operates at 25.5GHz with a maximum gain of 13dBi and directivity of 15 dBi with antenna efficiency up to 80.8% and achievable bandwidth of 1.4GHz at resonant frequency
