Abstract

Many high-frequency antennas have significantly smaller dimensions than the operating wavelength, causing a narrow bandwidths. This paper examines characteristic modes (CMs) of platform-mounted antennas to increase the overall bandwidth of the system. We use the theory of CMs to identify the appropriate platform modes and determine the practical feeding circuits. We fabricate a prototype platform antenna using a scaled model at 860 MHz to verify the simulation results.
