چکیده
This paper presents a design of trapezoidal microstrip patch with T-shaped slot.Trapezoidal patch is designed on a FR4 substrate having relative permittivity of 4.4and loss tangent of 0.0013.The substrate is having thickness of 1.6mm at which a trapezoidal patch antenna with Tslot 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. The proposed antenna is a wide band antenna with a band width of 62.83% and operates at the resonant frequency of 2.271GHz.Feed point on the patch that gives a good match of 50Ω. Keyword-Circular polarization-shape slot, wide band width microstrip patch antenna.

CPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications
A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...

some analysis has been presented on a circularly polarized microstrip antenna with T slot configurations in detail. Here we will design a T-slot coupled circularly polarized microstrip antenna in the frequency 1.575 GHz. The upper patch i.e. the radiating patch would be circular. There is no closed form expression so that by using that expression the dimensions of the proposed antenna could be ...
