Siddhartha Pal, Kousik Roy, Atanu Nag, Adarsh Kumar Tiwary

The paper represents a circular patch microstrip antenna functioning in a single band of frequency 10GHz. Moreover it shows the steps in details of designing the circular patch microstrip antenna along with its simulated product. From the outcomes, technique of the fabricated mobile antenna is established to have a good performance. The recommended Circular patch microstrip array antenna is essentially a phased array comprising of „n‟ elements (circular patch antennas) placed in a rectangular grid. The dimension of every element is decided by the operating frequency. The incident wave from satellite reaches at the plane of the antenna with identical phase across the surface of the array. Each and every „n‟ element achieves a little amount of power in phase with the others. Feed networks link every element to the microstrip lines with an identical length. Therefore the signals arriving at the circular patches are all joined in phase and the voltages combine together
