Analysis of Trapezium Shaped Microstrip Patch Antenna with A T-Slot for WLAN Application

Kaushal Prasad ^[2] | Dr. D. K. Srivastava

Abstract: This paper presents a Trapezium shaped microstrip patch antenna with T- slot. FR4 substrate are used to design Trapezium patch antenna. Substrate has relative permittivity 4.4 and loss tangent 0.0013. The substrate is having thickness of 1.6 mm on which a patch of Trapezium shape is designed with T- slot. The antenna is fed by 50 coaxial probe feed. The selected design is simulated using IE3D software. By analyzing the design of proposed antenna a broad band width of 67.25 % (2.38 GHz 4.79 GHz), and operates at the resonant frequency of 4.45 GHz. The proposed feed point on the patch gives a good match for impedance. Thus proposed antenna can be used for the wide band (2.38 GHz 4.79 GHz).
