Characteristic Mode Design of Chanel-Logo Shaped Antenna

Abstract

This paper introduces a Chanel-logo shaped antenna. By characteristic mode analysis (CMA), modal significance and modal radiation patterns of different modes were studied and find the suitable mode that can be easily excited. The Y-shaped feeding structure was chosen to excite the desired modes and have a good impedance matching. The simulation results indicated that the 10-dB return loss bandwidth of 2.5-4 GHz (46.2%) is obtained. This work demonstrates feasibility of future application in product advertisement.
