Compact slotted CPW‐fed Y‐shape patch antenna for Wi‐Fi and WiMAX applications

Abstract

A compact slotted Y‐shape patch antenna fed with a coplanar waveguide is described in this manuscript. The proposed antenna configuration comprises a modified rectangular slot printed on a single FR4 substrate which holds a Y‐shape patch antenna, and 2 equal length arms used to widen the impedance bandwidth. The antenna is manufactured and measurement results show good correspondence with the simulation analysis, with measured impedance bandwidth (defined for S11 ≤ −10 dB) of 44.9% (from 2.28 to 3.6 GHz) and stable gain larger than 2 dBi within the bandwidth of interest. The proposed antenna can be used for Wi‐Fi and WiMAX applications.

Wide‐bandwidth multifrequency circularly polarized monopole antenna for wireless communication applications

“… have been concentrated on multiband configurations, Refs. have tried to enhance the bandwidth and Refs. emphasize on circular polarization (CP) antennas.…”

“…So far numerous configurations have been reported in the domain of multiband operations. [1][2][3][4][5][6][7][8][9][10] Similarly, for bandwidth enhancement, many approaches have been reported by the researchers such as annular ring encircled by a rhombus strip, 11 desktop shaped microstrip patch, 12 U-shaped slot patch antenna, 13 E-shaped microstrip patch, 14 Y-shaped patch antenna, 15 U-shaped patch, 16 wide slot with parasitic center patch, 17 and curved slot. 18 On the other hand, circularly polarized [19][20][21][22][23][24][25][26][27][28] antenna in wireless communication system is another major application which minimized the effect of multipath reflection.…”
