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 is done with ground plan. Simulation results show that the proposed antenna can operate from 3.2GHz to 4.8GHz with low VSWRs less than or equal to 2. Stable antenna gain (dB) is also achieved over the entire operating frequency band.
