Broadband rectangular microstrip antenna loaded with a pair of U-shaped slot

In this paper analysis of double U-slot loaded patch antenna is presented. The parameter of the antenna significantly depends on slot dimensions. Bandwidth of the proposed antenna is found 21.59 %. The 3dB beamwidth of the antenna is found to be 90° for the central frequency of 1.9 GHz. The theoretical results obtained from the analysis are compared with IE3D simulated and experimental results which are in good agreement.
