This project is about the circular loop patch antenna design that operates in 900MHz frequency. The antenna is a single loop patch which lies on the surface of the dielectric substances, FR4. A 50 SMA RF port is attached at the end tip of the antenna for 50 coaxial cable connection. The antenna is designed and simulated using ADS software. The concerned parameters of the antenna are, S11, Gain and impedance. Apart from these, other concern parameters are radiation pattern and power also will be take into consideration when simulate antenna. At the end of the project, a working loop patch...
