Abstract
A simple dual-band dual-linear-polarization printed slot antenna is introduced in this paper. The main features of the antenna, besides a dual-band operation, is independent polarization in each band and small dimensions. The proposed slot antenna structure consists of an electromagnetically coupled fed main slot in the semicircular shape. The planar antenna has been designed to provide capabilities for implementation of a polarization/pattern/bandwidth diversity scheme in WiMAX and WLAN bands. The 10 dB return loss impedance bandwidths for the lower (WiMAX) and higher (WLAN) bands are 9% and 15.5%, respectively. This prototype has been fabricated and characterized. Measurements on a prototype of the proposed slot antenna confirm good performance in terms of impedance matching and polarization.
