نویسنده
چکیده
In this paper a new geometry of circularly polarized patch antenna is proposed with improved bandwidth. The radiation performance of proposed patch antenna is investigated using IE3D simulation software and its performance is compared with that of conventional circular patch antenna. The simulated return loss, axial ratio and impedance with frequency for the proposed antenna are reported in this paper. It is shown that by selecting suitable slot dimension, air gap and location of the slots, the impedance bandwidth can be enhanced upto 10.74% as compared to conventional circular patch (3.41%) with an axial ratio bandwidth of 2.46%.

متن کاملSimulation and Analysis of a T-Slot Coupled Microstrip Antenna with CPW-Fed using Ansoft HFSS
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 ...
