A design a patch antenna at frequency at 1.61538 GHz, The patch will be used as a feed for a TV offset feed dish and NASA light weight rainfall radiometer (LRR) and military aircraft. Therefore, we require a patch that will have a wide beam width to provide optimum illustration of the dish. Micro strip patch antenna is working on dual band of frequencies 1.61538 Ghz and 2.5463 Ghz. Therefore, this antenna can work as a smart antenna (An antenna which works on multiple frequencies). They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. By use of this combination it has been seen that there is a step up of return loss. These structures are simulated using IE3d Electromagnetic simulator of Zeland’s software incorporation.

Rectangular Microstrip patch antenna, Bandwidth, Dual band frequencies, return loss, Directivity, VSWR.
