技術摘要 / Our Technology:
本發明係一種圓形極化介電質共振器天線,該天線包括:一基板;一威金森功率分配器;一相位偏移器,連接於該威金森功率分配器;一接地層;以及一介電質共振結構,該共振結構包含一介電質本體與一溝槽,設於該基板上方;本發明之圓形極化介電質共振器天線係利用該溝槽的設計,增加該天線之線性極化傳輸頻寬,再藉由配置該威金森功率分配器,使該天線可發射及接收圓形極化電磁波,而可適用於衛星通訊、全球互通微波存取(Worldwide Interoperability for Microwave Access,WiMAX)及無線通訊等網路相關產品。
The present invention relates to a circularly-polarized dielectric resonator antenna (DRA). The antenna comprises a substrate, a Wilkinson power divider, a phase shifter, a ground plane and a dielectric resonator, wherein the phase shifter is connected to the Wilkinson power divider. Besides, the dielectric resonator is disposed on the ground plane, and includes a dielectric main body and a slot disposed above the substrate. Additionally, the antenna is adopted to increase the linear radiation bandwidth by utilizing the slot, and transceives a circularly-polarized electromagnetic wave by utilizing the Wilkinson power divider. Consequently, the circularly-polarized dielectric resonator antenna can be applied in the fields of satellite communication, Worldwide Interoperability for Microwave Access (WiMAX), and wireless communication.
