Abstract
Series feeds are commonly used in antenna arrays because of their compact size and low loss compared to corporate feeds but typically feature beam squint over wide bandwidths. This work proposes a series-fed waveguide horn array with reduced beam squint by introducing synthesized time delay sections between the horns and the feed line. The array, implemented in a WR42 waveguide, achieves 1.53° beam squint over a 4 GHz operating band, compared to 10.52° for a reference design without time delay compensation.
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.
