Electronically programmable beam direction of array antennas based on microcontroller

In this paper, an electronically programmable beam direction of array antennas is designed based on microcontroller. Array antennas which consist of 16 antenna elements are fed by the use of corporate feeding network design at 2.4GHz. To obtain beam direction which is electronically programmable, variable capacitor diodes are used as phase shifter for each antenna element at the feeding line. In order to achieve different beam direction, electronically technique which is based on microcontroller is applied in design controllable phase shifter.
