| Abstract: | The performance of a circularly polarized
edge truncated elliptical patch microstrip antenna has been investigated experimentally
in free space and has been compared with the performance of a conventional
elliptical patch antenna. Extensive optimizations in feed locations and in edge
lengths along major and minor axes of conventional elliptical patch
antenna have been carried out to achieve best performance from modified
elliptical patch geometry. In addition to circular polarization, proposed
antenna presents impedance bandwidth close to 180 MHz or 6.54%. With proposed
feed arrangement, right circular polarization with axial ratio 0.9 dB at
frequency 2.751 GHz is realized and axial ratio bandwidth close to 2.17% has
been achieved. The gain of proposed antenna is lower than desired value for
modern communication systems. In entire bandwidth, the radiation patterns are
identical in shape. |
