please help.... i designed a triple band antenna at 2.3,3.3, and 5.8 GHz. but when i measure it i get my antenna frequency shifted about 0.02 GHz to the higher frequency. i use Electromagnetic coupled for the feeding. can you tell me the reason and how to solve this. thanks before.....
What we are trying to say is that the computer analysis programs are not that accurate! No matter what you do, you might have to tweak the design in on the bench, or modify the artwork after initial testing.
