Design of Phased Array System Using V-Antennas For Beam forming Applications

摘要

This paper presents the design of phased array system using planar technology for beamforming applications. The prototype comprises of V-antenna, integrated with butler-matrix. The novelty in this approach is the design of V-antenna using planar technology which results in high directivity and multiband operation. The designed array structure is having maximum directivitiesby the individual antennas in the direction -44°, 136°, -136° and 44° which are approximately equal to theoretical values. The operating frequency of design is 2.4GHz. And the complete phased array structure is working at multiple frequencies, that is, at 2.4GHz as well as at 4.5GHz. As the size of the V antennas is smaller than the conventional microstrip antennas, the complete phased array system is compact in size. This is an added advantage along with multi band operation that can be used in devices of smaller size. The proposed design is well suited in satellite communications. The simulations were carried out in Advanced Design System Tool.
