Abstract

This paper presents the comparison of different DRA antennas and the modes of coupling the energy to a DRA antenna to its ports. The DRA is excited by a conformal inverted-trapezoidal patch connected to a micro strip line. The wider bandwidth is achieved due to several factors such as rectangular shape of the dielectric resonator and feed mechanism. The coupling mechanism has a significant impact on resonant frequency and Q-factor. A efficient bandwidth is achieved based on which antenna array structure is designed and the directivity increases largely. Various coupling methods have been described in this paper. The impedance bandwidth of the DRA can be calculated from the Q factor.
