: A modern, planar version implemented on a standard PCB using metalized via-holes to form the "walls," offering a compact and low-cost alternative for 5G and 6G technologies. Журнал Радиоэлектроники +9 Typical Applications Field Primary Use Case Radar Systems Used in naval ships, aircraft, and weather forecasting due to high power handling. Satellite Comms High-gain feeds for large reflectors and military satellite links. Consumer Electronics Microwave ovens use waveguides to distribute energy into the cooking chamber. Scientific Research Radio astronomy and high-frequency measurement systems. Manufacturing and Materials Traditional waveguide antennas are machined from solid blocks of high-conductivity metals like
: Their robust metallic structure allows them to handle much higher power levels than planar antennas. waveguide antennas
Here is a breakdown of why this feature is important: : A modern, planar version implemented on a
| Type | Description | Typical Application | |------|-------------|----------------------| | | Flared waveguide section that matches impedance to free space. | Gain standards, reflector feeds, EMC measurements. | | Slotted Waveguide | Longitudinal or transverse slots cut in waveguide wall to radiate. | Airborne radar, ground surveillance arrays. | | Waveguide Slot Array | Multiple slots in a waveguide or network of waveguides. | High-gain planar arrays (e.g., marine radar). | | Dielectric-loaded Waveguide | Partially filled with dielectric to reduce size or modify radiation. | Low-profile antennas, satellite comms. | | Leaky-Wave Antenna | Continuous aperture where wave "leaks" energy along length. | Frequency-scanned radars, automotive sensors. | | Corrugated Waveguide Antenna | Grooves inside aperture to control polarization and sidelobes. | Feed horns for radio telescopes, satellite downlinks. | Here is a breakdown of why this feature
: Used as feed antennas for parabolic dishes or as standalone high-gain antennas. 2. Slotted Waveguide Antennas
