<p>In this paper, an inset feed toppled H-shaped microstrip patch antenna with grounded plane is investigated for triple band operation. The simulation of proposed antenna geometry has been performed using IE3D simulation software based on method of moment. The prototype of the proposed antenna has been fabricated and tested to validate the simulation work. The measured results indicate that the reflection coefficient is better than -10dB for 1.8 GHz (PCS), 3.5 GHz (WiMAX), and 5.5 GHz (WiMAX) frequencies.</p>

A novel design of broadband patch antenna is presented in this paper. The broadband property of the proposed antenna is achieved by choosing a proper selection of dimensions and positions of slot and notch on the radiating patch. The bandwidth of the proposed antenna is found to be 30.5% with operating frequency band from 1.56 GHz to 2.12 GHz. Antenna characteristics are observed for different inclination angles “α” and its effect on bandwidths is also reported. The maximum gain of the antenna is found to be 9.86 dBi and it achieves broadside radiation pattern in the direction of maximum radiation over the operating band. The proposed antenna structure is simulated, fabricated, and tested for obtaining the desired performance. The simulated results are verified with experimental results which are in good agreement.
