A low volume flexible CPW-fed elliptical-ring with split-triangular patch dual-band antenna

In this article, the intensive investigations are carried out on a low volume compact flexible antenna for wireless applications with a novel structure model. The proposed model has considered as an elliptical-ring with split-triangular patch (ERSTP) antenna with the coplanar waveguide feeding to achieve dual-bands. The ERSTP antenna is designed with polyimide material having the volume (L-a x W-a x h) 99 mm(3). The ERSTP antenna resonates with 2.60 GHz and 3.48 GHz frequencies with a reflection coefficient of -21.92 dB and -32.14 dB and a gain of 2.39 dBi and 1.75, dBi respectively. The impedance bandwidths are 100 MHz and 330 MHz observed at two frequency bands. The proposed ERSTP antenna has operated on mobile-worldwide interoperability for microwave access (M-WiMAX) and worldwide interoperability for microwave access (WiMAX) bands respectively. The simulated and measured results of ERSTP antenna are in good agreement.
