Wireless communication technology is a fast developing technology which gives a huge impact on social life nowadays. This non wired technology urges a sturdy need for antenna development where antenna can be said as the core device for this technology. Researches on antenna are rapidly developing in the current research trend resulting in many antenna designs of various capabilities. Reconfigurable antenna is among popular designs in modern wireless technology because it allows single antenna to be employed in many systems. Originally, reconfigurable antenna can be categorised into three parts which is frequency, polarisation and beam pattern. This thesis is focusing on the beam pattern reconfigurable concept for antenna that operates at 2.45 GHz and 5.8 GHz band. This dual band reconfigurable is capable to steer the beam to three different directions by using only single design of planar array antenna. Three patch antennas are introduced in this thesis where these antennas are designed with the main beam facing three different directions. Partial ground plane and parabolic ground plane are used in developing the proposed reconfigurable antenna and finally, these patch antennas are combined with array configuration on single antenna design. This planar array reconfigurable antenna hence integrated with PIN diode as to make it a reconfigurable antenna. This proposed antenna can steer beams at -20°, -59°, and 61° at 2.45 GHz band while at 5.8 GHz band, proposed antenna can give steering angle of -9°, -20° and 23°. All the simulated and measured results are presented and compared in this thesis.
