Multi-Beam Conformal Patch Antenna Array for WAIC System Application

In this paper, a conformal patch antenna array with multiple directional beams for wireless communication in the cabin is proposed. Patch antennas operating in the band assigned for the Wireless Avionics Intra-Communications (WAIC) are chosen in the work for a wide signal-coverage in the cabin. Results show that, by accommodating the antennas’ position properly, good isolation between antennas can be achieved in a limited space, thereby ensuring the miniaturization and high radiation efficiency of the multi-beam array system. The proposed design has a compact and simple configuration, which can be a promising candidate for WAIC system applications.
