Probe Feed Microstrip Patch Antenna Computer Aided Design Methodology

Antenna is a means for radiating or receiving or transmitting energy an antenna is used in an advanced wireless system is usually required to optimize the radiation energy in same direction and suppress it in others. A microstrip patch antenna, also referred to as patch antenna is a narrowband, widebeam antenna fabricated by etching the antenna element patch in metal trace bonded to an insulating dielectric substance with a continuous metal layer bonded to opposite side of substrate which forms a ground plane. Probe fixed microstrip antenna is simulated in Finite Difference Time Domain software IE3D. Proposed novel probe feed microstrip patch antenna is presented. It has a return loss of -30dB at a frequency of 5.102 GHz. Antenna offers a bandwidth of 150.63MHz. In this research article proposed antenna bandwidth is improved by2.95%. Antenna offers a VSWR less than 1.1 at a frequency of 5.102 GHz. By observing twodimensional and three-dimensional radiation pattern, it is seen that antenna offers unidirectional radiation pattern. Unidirectional radiation pattern plays an important role in next generation mobile communication and computing. Due to Unidirectional radiation pattern, the cost of power is saved. Antenna offers maximum antenna gain of 4.17 dBi. Antenna offers radiation efficiency of 72.6%. Also, proposed antenna offers antenna efficiency of 72.6%.
