A Comparative Study for Designing and Modeling Patch Antenna with Different Electromagnetic CAD Approaches

This paper presents a comparative study for designing and modeling patch antenna with different electromagnetic computer aided design (CAD) approaches as CST, HFSS, FEKO and IE3D. The patch antenna is an insert feed type with a copper patch and Roger RT/duroid substrate as a case study. The Wi-Fi operating frequency of 2.45 GHz is chosen for the resonator design. The effectiveness and limitations for each modeled approach for this case study are discussed in term of the antenna performance analysis.
