Abstract
This article presents a new wide E-plane beamwidth rectangular microstrip patch antenna adopting H-shaped gap-coupling with three parasitic patches for the K-band vehicle parking monitoring system, while keeping single substrate. Both side and upper parasitic elements serve as λ and λ/2 resonators and are excited primarily by magnetic and electric couplings, respectively. The synthesis of radiation patterns from main and auxiliary elements results in the E-plane wide-beamwidth property. The proposed gap-coupling antenna provided the peak gain of 4.82 dBi, E-plane half-power beamwidth (HPBW) of 143.4°, and co-to-cross-pol ratios of 22.7 and 20.2 dB within the HPBW for the E- and H-planes, respectively. The presented geometry showed excellent figure of merits compared with others for the K-band.
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
-Measurements Interfaced with CAD Systems
In addition, the scope of the journal includes features such as software reviews, RF/microwave/mm-wave CAD related news, including brief reviews of CAD papers published elsewhere and a "Letters to the Editor" section.
