Smart Antenna with Dynamic Radiation Pattern Capability for 4G Applications
A 3600 beam switching compact planar patch antenna is presented in this paper. The designed antenna consists of three dipole radiators arranged in a hexagonal loop on a low-cost FR4 substrate. It achieves radiation pattern reconfigurability by switching the three PIN diodes. The selective surface current distribution leads to six different radiation modes of the antenna. The fabricated antenna proves beam rotation in entire azimuth plane in six different states at 600 steps. It offers a 100MHz common impedance bandwidth from 2.35GHz to 2.45GHz common between the two resonant modes of the antenna. In this common band maximum measured gain is 2.66dB with over 75% efficiency. The antenna has a compact size of 0.47λ0 × 0.47λ0 and a low profile of 0.012λ0. It has a significant impact on the 2.4GHz wireless applications due to its beamforming and beam rotation capability.
