Abstract:

Microstrip antenna are significantly used in current technological tendency i.e. in wireless communications. In integrated circuit technology coplanar waveguide (CPW) structure is generally used because of its design on the coplanar side of the patch. And it is one of the desirable characteristic of this type of technology. The gain is also the important performance parameter of any antenna. This paper presented the gain enhancement techniques of CPW fed microstrip antenna. The gain enhancement may be achieved by the array arrangement of antennas. Arrays are the arrangement of more than one element of patches in fruitful manner. In this paper the functioning enhancement by the gap between the patches of the array, has been analyzed. The gain has
been enhanced up to the 9.86 dB with the 4x1 linear arrays of the designed structure from 3.63 dB of basic single antenna structure. The antenna designed frequency has been taken as 2.4 GHz. The designs were simulated by licensed HFSS Software version 16.
