Abstract
In this paper a four element direct microstrip line feed hemispherical dielectric resonator antenna (HDRA) array is explored. Initially, a direct microstrip line feed HDRA is designed at 6.4 GHz and gain is observed as 5.2 dBi. The dielectric resonator antenna (DRA) is excited in its fundamental TE111 mode. Next, to enhance the gain a 1×4 linear array is designed. To feed the DRA elements a corporate type of feed network is employed. This is the unique feature of this proposed antenna. The gain is noticed as 10.7 dBi. The proposed antenna offers impedance bandwidth of 7.2% covering frequency range 6.35 GHz to 6.83 GHz.
