Compact Multiband Rectangular Microstrip Patch Antenna for S, C, And X Band

Abstract

This paper introduces the novel depiction of rectangular microstrip patch antenna on an affordable FR4 substrate of dielectric constant 4.4 and loss tangent 0.02. Ithas dimension of 40mmX 40 mm X 1.6 mm. The proposed multiband microstrip patch antenna can resonate at 2.55 GHz, 3.96 GHz, 5.38 GHz, 6.37 GHz, 7.78 GHz, 9.34 GHz, 10.89 GHz, 11.60 GHz, 12.17 GHz and 14.43 GHz. To achieve multiband frequency, three rectangular slots have been cut on the patch. The procured bandwidth is satisfactory and voltage standing wave ratio (VSWR) is less than 1.5. The execution of multiband antenna is simulated and attested by estimation. On the contrary, the proficiency of proposed multiband patch antenna has been justified through surface current distribution and efficiency of measured result.
