Design of Circularly Polarized Trapezium Microstrip Patch Antenna with A T-Shaped Slot
In this paper, the authors present a design of trapezoidal microstrip patch with T-shaped slot. Trapezoidal patch is designed on a FR4 substrate having relative permittivity of 4.4 and loss tangent of 0.0013. The substrate is having thickness of 1.6mm at which a trapezoidal patch antenna with T-slot has been introduced in this paper. The selection of design is based upon the dimension and location giving a better performance, VSWR, band width and radiation characteristics of these antennas are studied.
