Compact Wideband Printed Slot Antenna with a Star Shaped Parasitic Patch

In this letter, a technique for enhancement of bandwidth along with gain is proposed here. This article deals with design, modeling and simulation of slotted antenna. A star shaped parasitic patch is introduced in the centre of antenna to improve the gain along with the bandwidth by exciting additional resonances. For enhancing bandwidth, a slotted approach is used in ground of antenna along with rotation in patch and a simple 50 Ώ microstrip line fed is used to excite the slot in the antenna. Simulated results shows that a good amount of bandwidth (approx. 2.89 GHz) and gain (approx. 8.05 dB) is achieved ranging from 2.37 to 4.55 GHz using Ansoft HFSS software. The proposed antenna shows its application in WIMAX and WLAN bands along with comparative analysis between parasitic patch and without parasitic patch at the last
