In the present paper W-slot loaded single and two dielectric layers microstrip patch antenna has been analysed using equivalent circuit concept. The antenna shows dual resonance. The resonance frequency of single layer patch is found to be 2.91 GHz and 3.88 GHz which increases for two layers dielectric antenna up to 4.17 GHz and 5.78 GHz respectively. The frequency ratio is found to be 1.33 for single layer patch antenna and 1.38 for two layers patch antenna. In general the frequency ratio is found to depend on slot length, slot width and slot angle. The bandwidth of single layer patch antenna is found to be 1.71 % and 1.68 % for lower and upper resonance frequency while it increases for two layers up to 5.28 % and 2.77 % . The theoretical results are compared with the simulated results obtained from IE3D and both are in close agreement.
