本論文主要研究為環形介質諧振天線(Cylindrical Dielectric Resonator Antenna, CDRA)陣列,利用環形介質諧振器的高介電常數、低成本與低溫度係數等優勢,可以縮短波長的共振路徑,使天線達到小型化之效果。饋入方法採用共平面波導結構,使得環形介質諧振天線在設計上更具有靈活性。
巴特勒矩陣(Butler Matrix)的結構以延長路徑的方式來產生波束成形所需之相位差,而且同時還具有多輸入多輸出的特性,在不同的巴特勒矩陣之輸入埠饋入訊號,可以同時在輸出埠上產生不同的相位差,而此時電磁波會在某個方向產生建設性干涉,達到波束成形的效果。將四組環形介質諧振天線組成陣列,並分析其輻射特性與激發模態用來作為巴特勒矩陣之天線單元。
天線單元的量測增益為1.02 dBi,結合巴特勒矩陣的天線陣列之量測增益分別為3.63 dBi、3.12 dBi、4.36 dBi、2.57 dBi。

The main research of this thesis is the cylindrical dielectric resonator antenna (CDRA) array.Using the advantages of high dielectric constant, low cost, and low temperature coefficient of the cylindrical dielectric resonator, the resonance path of the wavelength can be shortened, and the antenna can be miniaturized. The feeding method uses a co-planar waveguide structure, which makes the cylindrical dielectric resonator antenna more flexible in design.
The structure of the butler matrix is to extend the path to generate the phase difference required for beamforming, and at the same time has the characteristics of multiple inputs and multiple outputs. Feeding signals into the input ports of different butler matrixes can produce different phase differences on the output ports at the same time. At this time, the electromagnetic wave will produce constructive interference in a certain direction to achieve the effect of beamforming. Four groups of cylindrical dielectric resonator antennas are formed into an array, and the radiation characteristics and excitation modes are analyzed to be used as the antenna element of the Butler matrix.
The measurement gain of the antenna unit is 1.02 dBi, and the measurement gain of the antenna array combined with the Butler matrix is 3.63 dBi, 3.12 dBi, 4.36 dBi, 2.57 dBi, respectively.
