In this paper, a coaxial fed rectangular microstrip patch antenna with a ring slot is proposed for S-band applications. The proposed antenna is having a dimension of 52.5x37.5 mm2 with a Rogers material as a substrate. The antenna resonating at 2.14 GHz with a return loss of -21.5645dB. The results are obtained by using the electromagnetic solver high-frequency structure simulator from ANSYS. The proposed antenna has the satisfactory characteristics as beam width along ∅=0° is 124.02° and along ∅=90° is 103.18°, Gain is 4.4452 dB, and voltage standing wave ratio is 1.4542.
