Hi, Gurus,
I want to build a big microstrip antenna with high gain.
But I need to evaluate its performance under -40deg and +85deg first.
I checked the substrate spec, and found that Er can vary in +85deg.
But how to evaluate the CTE effect on performance.
For example, I got one substrate CTE spec as following, do I need to expand the antenna dimensions according to the CTE factor to evaluate antenna performance?
Best,
Tony Liu
