This paper conducts a comparison between two different manufacturing technologies for a prototype in Groove Gap Waveguide. Both technologies are metallized 3D-printed plastic and mechanized aluminium. The prototype is a straight section with transitions to WR-28 that works in the frequency band from 28 to 30 GHz. The main properties of the technologies in terms of losses, weight and ease of manufacture...
Study of Substrate Integrated Waveguide and Gap Waveguide technologies used to manufacture some demonstration prototypes at Ka band for a low losses distribution network in a low profile antenna. A transmission losses comparison is presented using lossy and lossless dielectric substrates in the simulations for the different technologies at 30 GHz. Various structures such as transitions from WR-28,...
This paper describes a modular active antenna for satellite communications in the K/Ka band. The application is thought for mobile satellite communications and internet links, mainly for commercial airplanes. The impossibility to build full active antennas, including amplifiers in all the elements, leads to a modular semi active antenna. Here the module is a small subarray with complete phase control...
