Shipboard platforms have numerous antennas crowding topside space. Consolidating these antennas would require having antennas with multi-frequency capabilities. A Gregorian parabolic stacked antenna provides multi-frequency capabilities on a single pedestal which reduces the number of antennas required on a US Navy shipboard platforms. This Letter depicts the simulated design and radiation pattern results of a 1.9 m Gregorian parabolic stacked antenna that is capable of operating at the X-, K-, Ka- and Q-band frequencies at VSWR values <2:1. These frequency band capabilities allow for satellite communication links where two antennas that are currently fielded are operating within. The dual Gregorian parabolic stacked antenna presented is capable of operating at the same frequencies on a single antenna pedestal which would reduce the number of antennas required on shipboard platforms.

顶部射频系统整合与格里高利抛物面天线堆叠

舰载平台有许多天线挤满了上层空间。整合这些天线需要具有多频能力的天线。格里高利抛物面堆叠天线在单个基座上提供多频功能，从而减少了美国海军舰载平台所需的天线数量。这封信描述了 1.9 m 公历抛物面堆叠天线的模拟设计和辐射图结果，该天线能够在 X、K、Ka 和 Q 波段频率下工作，VSWR 值 <2:1。这些频带能力允许卫星通信链路，其中当前部署的两个天线在其中运行。
