Abstract
This paper proposed a new design of stacked ring rectangular microstrip antenna fed by coplanar waveguide to increase the bandwidth. The results shown that at frequency 2100 MHz the return loss value is -13.23 dB with VSWR 1,553; at frequency 2300 MHz return loss values -15.36 dB with VSWR 1,412 and at frequency 2400 MHz return loss values -29.93 dB with VSWR 1.224. The bandwidth of the proposed antenna is 560 MHz or about 25.38% at VSWR <; 2, which is catagorized as Ultra Wide Band antenna.
