Wideband Patch Antenna Design for Wi-MAX and WLAN Application with Modified Ground Plane

Abstract

The Microstrip Patch Antenna design for new emerging technologies is an area of extensive research these days because of their low profile and ease of fabrication. Antenna design presented in this paper is well suited for Wi-MAX and WLAN application. The antenna is providing -10dB bandwidth of 4.14GHz from frequency 2.5GHz to 6.6GHz which is coming under the standards of these two technologies and good results have been achieved in the return loss and radiation pattern of the antenna. The design is made of FR4 substrate with modified ground plane structure and by inserting rectangular slits between feed line and radiating patch was implemented to change the effective length of the antenna. The radiation pattern of the antenna is presented using CST Microwave Studio which is well suited for wireless application.

Design of High Gain Wideband Ku-Band Antenna Using Vertical Slits and Slots

“…The dimensions of the U-slot, L-slot and slits have been optimized and shown in Table 3. Finally slots and slits are etched on to the surface of patch and we got the desired wideband operation in Ku-band (12)(13)(14)(15)(16)(17)(18). As the designing of the wide band antenna performed using slitting and slotting technique so firstly an inverted Uslot is etched on the patch and then two L-slots are etched on the upper part of the patch to both left and right corner.…”

“…An antenna with stacked geometry and inverted configuration for wideband application was presented [11]. A wideband antenna with modified ground plane for Wi-MAX and WLAN application is presented and the antenna provides -10dB bandwidth of 4.14GHz between frequency range of 2.5GHz to 6.6GHz [12]. A novel approach by using a FSS (Frequency Selective Surface) and by cutting multiple U-slots for WLAN and Wi-MAX application was presented.…”
