The slotted waveguide has achieved most of its success when used in an omnidirectional role To make the unidirectional antenna radiate over the entire 360 degrees of azimuth, a second set of slots are cut in the back face of the waveguide. When looking straight at the face of the waveguide you will be able to see straight through both slots. Research Article Waveguide-Based Antenna Arrays for 5G Networks wave waveguide-based antenna arrays for 5G networks: a high-gain omnidirectional antenna array and a dual-band slotted waveguide antenna array. The latter one represents a progress on our previous work recently reported for 5G networks operating at 28GHz and 38GHz [17]. The novel design based on two different slot lengths has been success- Single-layer slotted post-wall waveguide array with compact ... Abstract— A single-layer antenna composed of four subarrays and compact low-loss feed-line structures connecting to an RF-module for 77 GHz automotive radar systems is presented. This antenna is based on a slotted post-wall waveguide array, which is integrated in a ceramic-filled PTFE substrate. The antenna gain

Wideband Coaxial to Ridge Gap Waveguide Transition ... Recently, ridge gap waveguides are considered as guiding structures in high-frequency applications. One of the major problems facing this guiding structure is the limited ability of using all the possible bandwidths due to the limited bandwidth of the transition to the coaxial lines. Here, a review of the different excitation techniques associated with this guiding structure is presented. Long Slots Array Antenna Based on Ridge Gap Waveguide ... Long Slots Array Antenna Based on Ridge Gap Waveguide Technology Abstract: Ridge gap waveguide (RGW) technology is used in the design of a frequency scanning antenna with high gain and directivity. A Quasi-TEM horn with shaped ridge is designed as a guiding structure between two metallic surfaces. The waves are suppressed beyond the shaped ...
