Abstract:
A compact wide-slot antenna fed by microstrip-line for wideband operation is proposed and studied. The proposed antenna consists of a microstrip-fed line and a wide rectangular slot with a reverse L-shaped slot. The proposed antenna resonates the 10-dB bandwidth from 2.17 GHz to 6.25 GHz, and these frequency bands cover the standard IEEE 802.11b/g (2.4--2.485 GHz) and IEEE 802.11a (5.15--5.35 GHz, 5.725--5.875 GHz) for WLAN applications and 2.5 GHz (2.5--2.69 GHz), 3.5 GHz (3.3--3.8 GHz) and 5GHz (5.25--5.85 GHz) for WiMAX applications. In order to remove unwanted bands, we used two methods to reject the bands. By inserting a strip in the slot of the broadband antenna, a reject frequency band from 4.13 to 4.95 GHz can be obtained; by etching a U-slot on the the broadband antenna, a reject frequency band from 2.96 to 3.17 GHz can be achieved. The slot antenna with dual band-notched for WiMAX operation has been obtained. Detailed design and experimental results are shown and discussed in this paper.
