DESIGN AND DEVELOPMENT OF CIRCULARLY POLARIZED DIFFERENTIAL FEED MAGNETO-ELECTRIC DIPOLE ANTENNA

ABSTRACT

A simple ultra-wideband, circularly polarized, magneto-electric dipole antenna with differential feeding structure is proposed. The differential feeding structure has been used not only to excite the proposed antenna but it also eliminates the need of balun. Electric dipole with novel semi concave shape has been designed to achieve circular polarization. Results indicate that the designed antenna achieves a wide differential impedance bandwidth of 133.3% in the frequency range 0.5 GHz-2.5 GHz, for VSWR below 2. The 3-dB axial ratio bandwidth is 70.9% in the frequency range 1.0 GHz-2.1 GHz. With the impact of semi-concave electric dipole, the designed antenna is able to achieve peak gain of 6.5 dBi. The antenna also exhibits broadside radiation pattern with almost identical E-plane and H-plane radiation patterns and low cross polarization, in the given frequency range. The antenna is suitable for various wireless communication applications meant for S band like telemetry and radar.
