Abstract

In this paper, three different configurations of planar antennas with a 100 Omega differential input impedance for dual-band WLAN applications, have been designed and compared. The proposed antennas provide dual-band operation in the 802.11a/b/g frequency bands without using a balun (balanced feeding). The best return loss performance has been obtained with the dual-band printed dipoles which are also characterized by a relatively straightforward design and tuning procedure. Measurements on constructed prototypes are shown at the conference
