Abstract: | 本論文設計一應用於毫米波頻段的相位陣列天線子陣列模組。此天線模組將陣列天線與環行器作結合,透過與環行器的整合可提供兩個獨立的天線端埠,來實現用於發射和接收系統的自足獨立波束成形網路。為了消除相位陣列天線所產生的光柵波瓣,子陣列模組的輻射場型有經過適當的設計與調整。本論文其主要目標為用一組架構去將天線的收發路徑分開,避免訊號的互相干擾與延遲,其實現方式為將環行器與一組2×2串列式陣列天線結合,此架構為三層PCB板結構,下層為環行器,上層為天線,發射與接收訊號為同一組天線,並利用環行器的特性即可將天線的收發路徑分開,且利用三層板的結構,可以將整體的面積大幅縮小,可將此結構視為一模組,利於模組化。第二階段將此模組排列成1×8的陣列天線,每個模組為子陣列,可將每組模組輸入不同的相位來達到波束偏移的效果。透過量測驗證,此天線模組具有良好的輻射特性,增益為7.2dB,可應用於5G通訊系統中。 This paper presents the design of a subarray module for the implementation of phased array of antennas at millimeter wave frequency band. In particular, two antenna ports are created to provide the possibility of implementing self-sufficient independent beamforming networks for the transmitting and receiving systems by embedding a circulator. The radiation pattern of the module is properly designed to avoid the appearance of grating lobes in the formation of phased array of antennas.The radiation characteristics of both the subarray module and the phased array of antennas are examined by numerical simulation and experimental measurement over the antenna prototypes. |
