Abstract: This article introduces a pioneering hybrid Dielectric Resonator Antenna (DRA) architecture, incorporating a Dielectric Resonator (DR) energized by a hexagonal ring patch through a microstrip feed. To enhance its performance, a ground structure modification is implemented by integrating a hexagonal slot. The combined hexagonal ring and DR configuration facilitate the realization of seven distinct operating bands, while the inserted slot in the ground structure significantly widens the antenna's impedance bandwidth. The proposed antenna demonstrates resonances at key frequencies of 5.1 GHz, 6.3 GHz, 7.1 GHz, 7.8 GHz, 8.3 GHz, 8.7 GHz, and 9.07 GHz. Moreover, the antenna exhibits a commendable gain exceeding 2 dBi and a directivity surpassing 4.5 across all resonating bands, highlighting its potential for a wide range of wireless communication applications.
