A Compact Wideband Slotted Patch Antenna for Wireless USB Dongle Application

Abstract

Design of Compact planar wideband antenna suitable for wireless universal serial bus (USB) dongle application is proposed in this communication. By simply cutting notches and engrafting types of slots into a rectangular patch introduces multiple resonances. When these are combined together, the bandwidth gets enhanced. The proposed microstrip patch antenna has wide bandwidth with 10-dB return-loss and covering the range from 4.8768 to 8.9523 GHz. 59% of bandwidth could be achieved with the aid of simple microstrip Line feeding technique with VSWR<2. These features make them very suitable for wireless local area networks (WLANs) applications. This design has an overall size of only 11× 15 ×0.8 mm3 and is very suitable for use in an USB device.
