It uses a direct transition from a coaxial connector and radiates from the open side of the waveguide. The antenna exhibits a wide bandwidth, an omnidirectional radiation pattern, and horizontal polarization and can be integrated into metallic structures. The physical principle and design guidelines are summarized. A prototype of the proposed antenna has been realized and demonstrated a wide measured bandwidth extending from 6.7 to 16 GHz, with radiation characteristics corresponding very well with simulations.en© Copyright 2013 IEEE - All rights reserved.A wideband omnidirectional horizontally polarized traveling-wave antenna based on half-mode substrate integrated waveguideJournal article002013029110.1109/LAWP.2013.22634920003199729000062-s2.0-8487882638318966Nguyen Trong, N.
