Abstract :
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.
