A Triple-band Suspended Microstrip Antenna with Symmetrical USlots for WLAN/WiMax Applications

Abstract

In this study, a triple-band suspended microstrip antenna with symmetrical U-slots is proposed for modern wireless communication systems. The antenna is specifically designed to acquire application in WLAN and WiMAX communication. Symmetrical U-slots in the radiator patch increase the number of resonances and improve the gain response. An appropriate air height was maintained between the ground plane and the radiator patch layer for improving bandwidth operation. The impedance characteristics of the antenna are enhanced using probe feeding techniques. The proposed compact antenna is designed on a single dielectric substrate of (30×25×1.56) mm3 . Parametric analysis of the proposed structure has been realized using IE3D software. This prototype exhibits maximum impedance bandwidth of 750 MHz and gain response of 7.28 dBi. The performance of the structure at three resonating bands i.e., at 3.3 GHz, 3.78 GHz and 5.3 GHz facilitate it to be applicable for WLAN/WiMAX systems.

Compact Multiband Microstrip Printed Slot Antenna Design for Wireless Communication Applications

“…Slot structures are commonly used to achieve bandwidth enhancement in multiband printed antennas. Traditional slot fractal shapes and other structures have been effectively used to design antennas with and multiband for a variety of wireless applications [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Sze et al [7] suggested a low profile dual-band Annular Ring Slot Antenna (ARSA) for the use in 2.4/5 GHz (WLANs).…”

“…The wide bandwidth characteristics are obtained from the use of monofilar stubs in a spiral form with a slitted uneven ground plane. Behera et al [19] suggested a floating slotted microstrip antenna with U shapes to excite three bands for modern wireless telecommunication applications. The antenna is aimed to serve for WLAN and WiMAX applications.…”
