A. Petosa et al., MICROSTRIP-FED ARRAY OF MULTISEGMENT DIELECTRIC RESONATOR ANTENNAS, IEE proceedings. Microwaves, antennas and propagation, 144(6), 1997, pp. 472-476
A novel antenna is presented consisting of an array of multisegment di
electric resonator antennas fed by a multilayer microstrip branch-line
network. A prototype array has been designed and fabricated at X-band
and its measured performance includes a gain peak of 15.4dBi with a 3
dB gain bandwidth of 17% and an efficiency of 66%. This array can be u
sed as a medium gain, wideband antenna, or can form a subarray in a la
rge low-profile structure for high gain applications.
