Abstract :
In this paper, a three-order equal-ripple bandpass filtering antenna design using capacitive-gap coupled asymmetrical-CPW resonator is presented. The asymmetrical coplanar waveguide consists of the left-side finite ground plane, which is similar to a strip and the right-side ground plane, which is a big ground plane. The operating bandwidth (5150-5825 MHz) was designed using conformal mapping technique and microwave-filter theory. However, it can be an antenna candidate due to the asymmetrical-CPW effect verified by simulated results, which show a -10 dB insertion loss and 70 % radiation efficiency.
