Abstract

A compact planar inverted-L diversity antenna for handheld terminals is provided. Three diversity antennas operating at 2.15 GHZ are designed. The isolation is found to be better than 13dB and the usable bandwidth is about 13% in measurement. The measured radiation patterns are obtained that the proposed diversity antenna attains 2 dBi gain. Furthermore, the diversity performance is evaluated by calculating mean effective gain (MEG). Both azimuth and elevation spectrum are considered. Closed-form expression for MEG is presented, and the effect of some parameters on MEG is analyzed numerically in indoor propagation environments.
