- Abstract
- This paper proposes a pattern reconfigurable high gain spherical dielectric resonator antenna (DRA) operating on higher-order mode. Two microstrip patches were used to excite TE301 mode in the different direction. A reconfigurable switch network was designed and it has three switching modes for selecting each patch alone or selecting them simultaneously. The proposed antenna can reconfigure its radiation pattern by using a feeding structure which is consist of two microstrip patches and the reconfigurable switch network. A prototype antenna operating on TE301 mode at 5.8GHz was fabricated by ceramic material. By experiment, we validated the new concept of pattern reconfigurable spherical DRA. IEEE
