Beam Tilting Antenna using Varactor Diode
The objective of this paper is to design a patch antenna array system that is able to tilt the major lobe of radiation pattern in different directions. From different tilting methods available, phase shifting method is most appropriate for the designing. The direction of the beam is expected to change in different directions by changing the phase of input signal. The phase variation of input RF signal is obtained by using varactor diode. Simulation and designing of 2 x 2 patch array corporate feed network was performed on ANSYS HFSS at a frequency of 2.4GHz. The implementation of this design will help in picking up the signals from desired direction. In this project the beam tilts approximately 8 to 10 degrees in a particular direction.
