ABSTRACT: This paper represents the performance analysis of the different shapes of antenna
balun and feeding techniques for step constant tapered slot antenna. This work
also addresses the benefits of antenna balun (circular and rectangular) along
with two types of feeding techniques (Microstrip line L-shape and Microstrip
line I-shape). The performance of the antenna for each technique is thoroughly
investigated using Computer Simulation Technology (CST) Microwave Studio
software simulation under the resonant frequency of 5.9 GHz. Results
demonstrate that the proposed model is an effective tool for improving antenna
performance. Moreover, an extensive comparison has been carried out between the
two different shapes, with and without antenna balun and between two feeding
techniques focusing on return losses, gain, directivity, and voltage standing
wave ratio (VSWR).
