Design and Analysis of Irregular Hexagonal Patch Antenna Using Multiport Network Model (MNM)
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.
期刊介绍：
International Journal of RF and Microwave Computer-Aided Engineering provides a common forum for the dissemination of research and development results in the areas of computer-aided design and engineering of RF, microwave, and millimeter-wave components, circuits, subsystems, and antennas. The journal is intended to be a single source of valuable information for all engineers and technicians, RF/microwave/mm-wave CAD tool vendors, researchers in industry, government and academia, professors and students, and systems engineers involved in RF/microwave/mm-wave technology.
Multidisciplinary in scope, the journal publishes peer-reviewed articles and short papers on topics that include, but are not limited to. . .
-Computer-Aided Modeling
-Computer-Aided Analysis
-Computer-Aided Optimization
-Software and Manufacturing Techniques
-Computer-Aided Measurements
