X-Band Linear Dielectric Resonator Antenna Array Fed by Dielectric Resonator Power Divider Array

摘要

A linear array of rectangular dielectric resonator antennas is analyzed in the X-Band frequency range with a new proposed feeding network. The feeding network is based on 1:6 power dividers. The power divider is made from a bow-tie shaped dielectric resonator enclosed by a cylindrical cavity. This provide a one level division rather than using more than two levels of feeding network based on 1:2 power dividers. The simulated results are verified with measurements. Good agreement between simulated and measured results is achieved.
