Modeling and simulation of an X-band planar phased array antenna

In fields like medical science, communication, weather forecasting and defense industry, active phased array radars is a revolutionary development, due to its benefit of beam steering over conventional radar. Small size, light weight, efficient and high gain antenna array design are important areas of research in active phase array radar that can meet the subject requirements. Paper presents compact micro strip patched phase array antenna at X-band. The design process, along with the simulated results of beam steering, is presented. Simulations were carried out in Momentum — an Electromagnetic (EM) simulation tool of Advance Design System (ADS) software. Simulated results matched well with the theoretical values.
