Abstract Details

2016, Master of Science (M.S.), University of Dayton, Electrical Engineering.
The main objective of this research is to develop an antenna array that can tune its radiation pattern over a fixed frequency of operation. For this purpose, a novel printed antenna array for beam peak shifting applications is presented. This antenna array consists of two bowtie slots separated over a distance of half wavelength. A conductor backed coplanar waveguide (CBCPW) is designed with signal line of one wavelength connected to the bowtie antenna linear array. The bowtie antenna surrounded by CBCPW ground lines acts as a radiating element. The frequency of operation of this array is 9.27 GHz which is reconfigured by the tuning varactors loaded on the signal line of one of the antenna in the array. After varying capacitance of the varactors on the signal line of CBCPW, alters the S parameters of the antenna array. The return loss of the antenna array in the frequency of operation is below -10dB, which suits the requirement of a working antenna. The radiation pattern of the antenna array is tuned as its beam shifts over a range of 10 degrees to 27 degrees.
