Design, fabricate and testing of feed network for 2X2 array antenna

This project describe the design, fabricate and testing of feed network for 2times2 array antenna. This feed network was designed using Microwave Office 2004 with applied Wilkinson power divider to develop the design. The circuit was fabricated on a microstrip substrate with a dielectric constant epsivr =4.7, tan sigma =0.019 and thickness =1.6 mm. The project that had developed can support at IMT (International Mobile Telecommunication) 2000 band which is operating at frequency of 1.8 GHz to 2.2 GHz with mobile station transmitting and it applied to many microwave and millimeter-wave systems and devices such as antenna feeders, power amplifiers, etc.
