Abstract :
This paper presents experimental results on a 3-element conformal K-band antenna array operating in the 18-26.5 GHz. The results demonstrate that a focused beam can be obtained and steered using the central focusing element of the array. The array has potential application in microwave hyperthermia, where the beam should focus on the tumor area, but direct minimum power onto neighboring healthy tissue.
