ABSTRACT

This paper provides possibilities to design a low profile, lightweight and mechanically robust Magneto-Electric dipole antenna for satellite communication. The antenna consists of horizontal T-shaped electric dipole, an inverted U-shaped feed line, a truncated ground plane and two directors to increase the gain. The antenna possesses wide impedance bandwidth of 90.9% in the frequency range, 1.5 GHz-4.0 GHz and provides circular polarization in dual bands. The 3-dB axial ratio bandwidth of 12.5% and 20.8% has been achieved in the frequency range 1.5 GHz-1.7 GHz and 3.0 GHz-3.7 GHz, respectively. The reported peak gain is 7.5 dBi with symmetrical E-plane and H-plane radiation pattern. To verify the ruggedness, the antenna has been mounted at two different positions over the car and good electrical and radiation characteristics have been observed, hence, making the antenna suitable for satellite communication.
