本論文主要研究應用於大型基地台之雙極化天線設計,操作頻段均於3300 ~3800 MHz,應用於LTE Band42、Band43與Sub-6 GHz n78,屬於第四代及第五代行動通訊頻段。
第一款基地台單元天線由兩對交叉葉片形狀的環型偶極天線、T型寄生元件及反射板組成,饋入採用同軸纜線直接饋入,為了突破直接饋入天線頻寬上的限制,在偶極天線上方增加寄生元件,利用天線與寄生元件之間的強耦合,可有效增加天線模態,達到阻抗頻寬擴增的功能,而為了使天線有良好極化分集的效果,天線形式採用正交±45°擺放。
第二款基地台單元天線將第一款環型偶極天線末端由金屬線連接起來,使天線激發路徑改變,可有效縮小天線整體尺寸,並利用正交擺放的巴倫電路進行饋入,通過微帶線轉阻的功能,天線能夠更容易達到阻抗匹配,進一步增加頻寬,而巴倫電路正交設計能使天線有穩固的結構及良好隔離度的效果。
兩款天線為了能讓基地台能夠涵蓋更廣的範圍,採用1×4陣列方式排列,使天線單元間的場型互相擠壓,形成具有高指向性的場型,而此兩款陣列天線皆為高增益天線。

The main objective of this thesis was the design of the Hybrid-Resonator Antennas which applys to the base station. The operating frequency bands are all from 3300 MHz to 3600 MHz. It can be covering LTE/Sub-6 GHz Band42 or n78, spanning the fourth and fifth generation mobile communication specification.
The first section of the base station antenna unit is designed by the loop dipole antenna in double cross blade, t-type parasitic elements and reflectiver; which is directly feed in cable line. To break the limitation of directly feeding in antenna bandwidth, we add parasitic elements on dipole antenna because of the close coupling between antenna and element units. It can effectively increase the antenna modal and the bandwidth, and make antenna reach to well polarization diversity. The antennas are place crossing 45 degree.
The second section of the base station antenna unit connects the end of the loop dipole antenna with metal wire. The metal wire can trigger the antenna to change the trail and also effectively shrink the size of the antenna.We used orthogonal balun to feed in. By the trans impedance of microstrip, antenna became easier to be impedance matching and also broaden the bandwidth. The orthogonal of balun could make antenna has firm structure and be well-isolation.To broaden the coverage of the base station, these two sections of antenna use 1x4 arrays to make the antenna units squeeze each other, which cause highly-directional antenna pattern. Both of them are high gain antenna.
