本論文提出涵蓋4G/5G頻段應用於小基地台天線，並藉由改變天線擺放組合，使在有限空間內不同天線之間的隔離度都能同時達到一定的標準。本論文所提出的小基地台之整合式天線除了能涵蓋LTE Band 2/7/12/66、5G-n78，其中還利用平面垂直設計、雙極化天線設計以縮小天線設計空間並達成相互隔離度的標準。本論文也針對設計出來的天線使用多種不同的擺放方式，用模擬的方式探討其使用不同擺放方式對每支天線所造成影響，參考模擬後實做出從中得到最佳特性的擺放方式。

This paper proposes to cover the 4G/5G frequency band and apply it to small base station antennas, and by changing the antenna placement combination, the isolation between different antennas in a limited space can reach a certain standard at the same time. In addition to covering LTE Band 2/7/12/66 and 5G-n78, the integrated antenna for small cells proposed in this paper also utilizes a vertical plane design and a dual-polarized antenna design to reduce the antenna design space and achieve mutual isolation. degree standard. This paper also uses a variety of different placement methods for the designed antennas and uses a simulation method to discuss the impact of different placement methods on each antenna. After referring to the simulation, the placement method to obtain the best characteristics is actually made.
