In the present communication the design and analysis of L-strip proximity fed disk patch antenna is presented. The variation of horizontal and vertical length of L-strip has been investigated in circular disk patch antenna. The bandwidth of the antenna is found inversely proportional to the horizontal length of L-strip whereas it is almost invariable with vertical length of L-strip. Typically the bandwidth of this antenna is found to be 16.63 % with maximum gain of 8.515 dBi. Further Lstrip proximity fed U-slot loaded disk patch is studied. In this geometry bandwidth of the antenna increases up to 37.01% when the vertical length of L-strip is 6.5 mm, but there is marginal effect in the bandwidth with the variation of horizontal length of L-strip.
