Radar systems transmit high power to survey long distances, which needs a costly component to handle such a power. Array and phased array antenna can accomplish this purpose with low power component, but with more complexity in design and control. Also tracking radars require antennas with sophisticated beam shape with specific characteristics such as narrow beam width and ability to scan the coverage with high data rate. These requirements lay a great burden on radar system’s designer to satisfy the characteristics of surveillance and tracking with one beam. Carefully designed phased array antenna may solve the problem of surveillance and tracking simultaneously, realizing the well-known Track – while- Scan technique (TWS). This paper focused on the issues related to the model, design, and simulation of phased array of dipoles antenna in CST Microwave software. A pencil beam that has 2.1o half beam power width HBPW that can be electronically steered to scan in elevation plane has been developed and tested against the design requirements. Array antenna gain of more than 34dB and array antenna efficiency more than 98% are achieved from the current design at desired frequency of 1.3GHz.
