In this video, we will see the complete design process on a small example, starting from the single element selection, over Unit Cell and the Finite Array Simulation, the radome integration and some simulation techniques that are commonly used for array simulations.
We focus on Arrays, especially phased arrays. But what are they? Perdefinition, an antenna array consists of many radiators in close proximity, and the sum of all single radiation patterns will give us a high gain compared to the single element. For sure they will influence each other due to the proximity, the elements have normally a strong mutual coupling. During the design of the array these effects must be considered.
But why do we need phased arrays? By controlling the phase of each single element we can control the beam direction without moving the antenna and without changing the geometry.
Antenna Magus is a great tool for exploring different designs and identifying candidate elements for your array. And once we’ve identified candidates, we need to evaluate them using CST Studio Suite. First, as a standalone element to make sure that we have an element that could in principle radiate as desired by the specifications. (if you already have a high quality element you might skip this step). Second, very importantly, considering mutual coupling effects from neighbouring radiators, as an element of an infinite array. Will this element work as part of an array? There are many tools and methods that will help you to answer these questions.
