נראה מעניין
איני חושב שזוהי צלחת אופטית או שזו ההגדרה הנכונה

Project Objectives
The objective of this project is to develop two 'Ku-band waveguide lens antennae' for satellite communication. The particular application here is satellite TV reception. There is an eventual possible application for reception of a large signal span in one antenna while the other receiving array (antenna) can be used in a variety of other applications.
The patented waveguide lens techniques allow multi-satellite reception in an angular coverage of 30°, and a satellite angular separation down to 2°. One antenna type is designed for the frequency band 10.75-12.75 GHz, which is the frequency range used for satellite TV in Europe. In North America, however, the corresponding frequency band 11.7-12.75 GHz is used. The second antenna type is designed for that band. The antenna can, however, be designed for mass production for any frequency band from 4-40 GHz.
One of the goals of this project has been to develop cost effective mass production methods in order to commercially exploit the waveguide lens technology to a mass market. The different mass market segments have been identified by a market study. In this study the demands of e.g. antenna shape and size as well as signal processing characteristics were analysed.
A production plant has been implemented and there is continuous manufacturing of the product.
