| Summary: | This dissertation presents an innovative design for a shared aperture dual-band, dual-polarized dielectric resonator antenna (DRA) targeting advanced 5G and 6Gmillimeter-wave (mmWave) applications. The proposed design addresses the growingdemand for compact and efficient antennas capable of operating across multiple bands with polarization diversity, essential for high-capacity, next-generation wireless communication systems. Initially, a dual-band hybridDRA is introduced, incorporating strip, slot, and dielectric resonator elements to achieve operation in the 28GHz and 38GHz bands. By leveragingdifferent resonantmechanisms, this antenna structureachieves awide bandwidth, covering the necessary frequencies for 5GmmWave applications. Subsequently, the study explores an alternative feedingmethod using an L-probe to realize a dual-band, dual-polarized DRA with enhanced performance characteristics.
This second configuration extends the antenna’s capabilities by providing stable dual-band functionality and dual polarization, therebymeeting the rigorous demands of base station arrays.
To support these designs, foundational antenna theories and parameters are discussed, alongside a reviewof recent advances inDRA technology. The study also highlights the necessity of shape innovation inDRAs and evaluates various feed strategies to optimize performance. The proposed designs provide ver
satile and high-performance solutions, paving the way for efficient, broadband mmWave communication systems suitable for future 5G and 6G applications. |
