Ansari, Anurag Mishra, N. Yadav, P. Singh, B. Vishvakarma] In the present paper a dual frequency resonance antenna is achieved by introducing L- shaped slot in circular disk patch. It is analysed by using circuit theory concept. The resonance frequency is found to be 5.087 and 8.455GHz and the 10dB bandwidth of the proposed antenna for lower and upper resonance frequency is found to be 4.39 and 4.66% respectively. It is easy to adjust the higher and lower band by changing the dimensions of notch and slot introduced in the antenna. The frequency ratio is found to be 1.6621. The gain and efficiency of the proposed antenna is found to be 9.50dB at lower resonance however it is 7.0dB at upper resonance frequency whereas the efficiency at lower and upper resonance is found to be 94.6 and 88.2%.The theoretical results are compared with IE3D simulation results which are in good agreement.
