ABSTRACT:
This invention is to provide a composite material for dielectric lens antennas which contains 3-70 percent by volume of a high dielectric constant ceramic and 30-97 percent by volume of a macromolecular material. At this time it is desirable that the mean particle diameter of the high dielectric constant ceramic is 1-50 .mu.m. It is also preferable that the macromolecular material is a thermoplastic macromolecular material. A dielectric lens is made of this composite material for the dielectric lens antennas. Further, the dielectric lens antenna is preferably produced forming a matching layer on the dielectric lens surface.
