Performance Comparison Between 2×1 and 2×2 Corporate Feed Antenna Array in X-band

In recent trends the advent in smart antenna system is based on light weight and low cost antenna array designed to perform well in high frequencies. However it is known that for better performance in wide range of high frequencies, microstrip antenna is the best possible choice. In this paper we constructed a corporate feed rectangular microstrip patch antenna and converted them into array. The design, simulation and fabrication of two linearly polarized 2 × 1 and 2 × 2 element microstrip array has been done and comparison is made in terms of different antenna parameters like radiation pattern, return loss, VSWR (voltage standing wave ratio), reflection co-efficient, gain and %bandwidth. We realized that the 2 × 2 antenna array performed better in terms of increasing directivity, gain and efficiency.
