DIELECTRIC RESONATOR ARRAY ANTENNA
First Claim
1. A dielectric resonator array antenna comprising one or more series-feed type array elements installed to be arranged in parallel in a multilayer substrate,wherein first high frequency signals having the same or different phases or time delays are adjusted to be applied to the respective series-feed type array elements and respective radiated 1D array beams are individually used or combined to adjust beamforming of 2D array beams.

Abstract
Disclosed herein is a dielectric resonator array antenna including one or more series-feed type array elements installed to be arranged in parallel in a multilayer substrate, wherein first high frequency signals having the same or different phases or time delays are adjusted to be applied to the respective series-feed type array elements and respective radiated 1D array beams are individually used or combined to adjust beamforming of 2D array beams. Also, since the series-feed type array element is configured by connecting a plurality of dielectric resonator antennas in series, it can be easily and simply fed in series through coupling generated by the intervals between the feeding lines of the pertinent feeding unit of the plurality of dielectric resonator antennas connected in series. In addition, the broadband characteristics can be obtained by using the plurality of dielectric resonator antennas, whereby the overall antenna performance can be enhanced.
