A MICROSTRIP-FED MONOPOLE ANTENNA FOR WLAN USB APPLICATIONS.

A compact design for a dual-band inicrostrip-fed antenna for WLAN USB is presented. The antenna structure consists of a bent copper sheet and a 50 Ω microstrip line. By adjusting the shape and dimensions of the copper sheet, the dual-band characteristics of the proposed antenna can be obtained, The measured bandwidth of the proposed USB antenna covers the WLAN bands (2.45/5.2/5.8 GHz) with a return loss greater than 10 dB. Furthermore, the effect of the metal below the USB antenna is also investigated. Details of the antenna design and experimental results of the constructed prototypes are presented and discussed.
