A Planar Beam-Switching Antenna Module for Full Horizontal Plane Coverage is composed of antenna elements, phase shifters, a proposed beamformer with generalized mathematical formula, and a proposed switch collaborated with Professor Kun-You Lin's Lab (MICSLab). By equipping drones with the antenna module, a collision avoidance FMCW radar system could be realized with the features of lightweight, cost-effective, great flexibility and better radiation performances compared to the conventional phased arrays.

This study will focus on planar reconfigurable antennas and array applications, combining state-of-the-art LCD technologies. Liquid crystal is well known for its dielectric anisotropy. The tunability of liquid crystal is taken into the design, which can achieve some functions such as frequency adjustment, polarization switching, phase shifting, and beam scanning. This technology is suitable for civil, military, and satellite communications.

A Spatially Recofigurable Phased Array (SRPArray) is composed of antenna elements separately carried by multiple UAVs. By relaxing the limit on its spatial arrangement of antenna elements, the SRPArray has potentially better deployment flexibility and performance than conventional phased arrays.

A Wide-Angle Scanning Antenna Array (WASA Array) consists of the antenna array elements and a metamaterial layer on top of the antenna array. By optimizing the metamaterial layer with antenna array, the WASA Array has conceivably a better scanning performance than conventional phased arrays. The antenna array can be designed using the Ansys HFSS simulation software, and the optimization can be completed using a MATLAB/Python program. The applications of the WASA Array are in Satellites, Military use, etc.

A Wide-angle Scanning Phased Array deals with impedance mismatch issue when array is scanning, especially when the mutual coupling between elements cannot be ignored. Using metamaterial layer or other approaches, the scanning volumn and bandwidth can be enhanced. The applications of the wide-angle scanning phased array are in satellites, mobile communication, military use, etc.
