摘要：Here, a printed micro strip line fed wide slot antenna with rotated square slot resonator is presented. This article deals with design, modeling and simulation of slotted antenna. A parasitic patch is introduced to improve the gain along with the bandwidth. For bandwidth enhancement, 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. The proposed antenna exhibits the return loss (S11) below -10 dB for the frequency mentioned and the effects of design antenna parameters such as slot width and patch width have been investigated. Results shows that a good amount of bandwidth (approximately 3 GHz) and gain (approximately 8 dB) is achieved ranging from 2.23 to 5.4 GHz which shows its application in world interoperability for microwave access (WIMAX) and wireless local area network (WLAN) bands.
