Abstract
This thesis has two parts. The first and foremost part was to design a patch antenna array of four elements that operates at 2.4 GHz. It was necessary that the patch array have adequate performance in return loss, specifically at the resonant frequency, and that the elements were separated enough to detect individual element differences in the return-loss parameter. The second part was designing and simulating a procedure to observe S-parameter changes when electrically conductive objects were placed near the array. Data from simulations was observed and recorded. This thesis outlines a first-order algorithm to passively detect objects near a functional antenna array through monitoring the S-parameters of each element of the array.
