Abstract

In wireless communications, conformal antennas such as the slot antennas are integrated into the portable terminals. However, the energy of the annular ring slot antenna will radiate into the whole space, so a triplate structure is chosen to back-up the slot and increase the radiation efficiency into the upper half space. The mixed potential integral equation (MPIE) based on the moment method is used to analyse the the frequency behaviour of the return loss, impedance and radiation characteristics of this antenna.
