Abstract

A tri-band Cylindrical Dielectric Resonator Antenna (CDRA) array is proposed for WiFi, wireless LAN, and satellite applications in this paper. CDRA is massively demanded by various smart wireless devices. The claimed antenna array structure is developed and fabricated using an FR4 substrate having relative permittivity (εr) of 4.4. Microstrip power divider line is utilised for array excitation. The variation in return loss due to effect of varying micro strip line length, dielectric resonator height and ground plane height has been carefully recorded and presented using parametric study. The array structure is engineered for triple band operations working at 2.4 GHz, 4.1 GHz, and 5.4 GHz frequencies. To achieve adequate bandwidth accompanied by acceptable gain is a very inspiring task. The proposed structure shows a promising maximum impedance bandwidth of 1.14 GHz (40%) and a maximum gain of 9 dBi. The return loss and radiation pattern computed through CST software are verified by practical measurements using VNA device and anechoic chamber atmosphere.
