Abstract

A three notch multilayer antenna for C-Band applications is presented in this paper. The proposed antenna is composed of a FR-4 and air gap Dielectric material, By introducing the two parts, the impedance bandwidth of the antenna can be significantly enhanced. Analysis done with ground plan. Simulation results show that the proposed antenna can operate from 3. 2GHz to 4. 8 GHz with low VSWRs ? 2. Stable antenna gain (dB) is also achieved over the entire operating frequency band. Furthermore, the size of the proposed antenna is very compact, which is only at the centre of the operating frequency band.
