Irregular Hexagonal shaped antenna for UWB Applications

Multiport network model (MNM) of microstrip patch antennas is an extension of cavity model analysis. In MNM, electromagnetic fields present under and outside patch are modeled separately and the patch is considered as a planar element with multiple ports at its edges. The MNM approach was previously used for the analysis of different patches such as rectangular and circular. However, MNM analysis for irregular‐shaped hexagonal patch antenna is not studied yet. Analysis of hexagonal patch antenna is required for its several advantages over other patches such as equivalent surface current distribution with less size compared to circular patch and higher bandwidth. In this work, the irregular‐shaped hexagonal patch antenna is analyzed using MNM technique. The antenna is decomposed into rectangular and right‐angle triangular segments. Multiport impedance (Z) matrices are calculated for all elements based on Green’s functions of corresponding shapes. Finally, the current distribution of the complete patch is obtained by connecting these elements using Z matrices. The irregular‐shaped patch antenna is fabricated, and its responses are measured to verify the results obtained from MNM analysis. MNM can estimate antenna performance with ~3.5% average error with respect to simulated responses in terms of antenna performance parameters.
