Abstract :
A novel antenna is presented consisting of an array of multisegment dielectric resonator antennas fed by a multilayer microstrip branch-line line network. A prototype array has been designed and fabricated at X-band and its measured performance includes a gain peak of 15.4 dBi with a 3 dB gain bandwidth of 17%, and an efficiency of 66%,. This array can be used as a medium gain, wideband antenna, or can form a subarray in a large low-profile structure for high gain applications
