Switched beam antenna system design

This paper described the design and implementation of switch beam antenna array system operating at 2.4 GHz frequency band. In this paper, four beam patterns are generated by incorporated with four dielectric antenna array and butler matrix. The PIN diode worked as a swicth while the PIC microcontroller used to control the beam pattern by setting the time delay between the beams. The result showed that the multibeam radiation pattern can be produced using this system.
