The patch antenna can be used as a feed for radar, Biometric devices and military aircraft. Therefore, we require a patch antenna that will have a wide beam width to provide optimum illustration of wireless communication. Micro strip patch antenna is working on frequencies 1.5789 GHz & 2.5263 GHz; it is a dual band antenna. The s- parameter clearly represents the multi bands with -10db and -17.5db at 1.5789 GHz & 2.5263 GHz respectively. Represents the VSWR (voltage standing wave ratio) of triangular slot antenna whose value should be between 1 and 2. It is used to measure the efficiency of transmission lines. The value of VSWR for the antenna is less than 2 for both 1.5789 GHz & 2.5263 GHz Radiation pattern is the graphical representation of relative field strength of antenna. Generally, the antenna should not have any side lobes. Even if they are present we cannot eliminate them instead we should minimize them the pattern of rectangular patch antenna. The radiation pattern of triangular slot patch antenna 1.5789 GHz & 2.5263 GHz .The directivities are 7.28dbi and 9.3dbi respectively. 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 Zealand software incorporation.
