Abstract
ABSTRACTA substrate integrated waveguide (SIW) offset parabolic antenna is proposed in this letter. The antenna consists of four main parts: a feeder with a horn radiator, a parabolic reflector, parallel plate metal blocks, and a dielectric load. The configuration of the horn and parabolic reflector is based on the parabolic reflector principle. The parallel plate metal blocks and the dielectric load improve the impedance matching and radiation performance of the antenna. Measured results show that the antenna is very well matched in the V‐band and the gain of the antenna in end‐fire direction varies from 13.2 dBi to 16.8 dBi. © 2016 Wiley Periodicals, Inc.
