A compact microstrip-line-fed printed parabolic slot antenna for WLAN applications

This paper presents a compact microstrip-line-fed printed parabolic slot antenna for wireless local area network (WLAN) applications in IEEE 802.11/b/g/a. The proposed antenna consists of a microstrip-fed-line and parabolic slot with a rectangular slot. By introducing rectangular slot with parabolic slot and a loading strip protruded into the rectangular slot, the proposed antenna can achieve two operating bandwidths. The measured impedance bandwidth of proposed antenna covers the operating bands of 2.4-2.84 GHz and 4.13-5.83 GHz, which covers the required bandwidth of WLAN applications. In measured results, good radiation characteristics are obtained.
