<p><P>PROBLEM TO BE SOLVED: To provide a dielectric lens antenna including a snow melting function without degrading the efficiency of a lens and a communication apparatus using it. <P>SOLUTION: In the dielectric lens antenna 10 constructed by attaching and holding a lens 2 made of a dielectric to and on a frame 3, a heating element 11 composed of a plurality of heating wires is formed on the front surface of the lens 2. A current is passed through the heating element 11 at the time of snowfall and snow accumulation, and snow attached on the front surface of the lens 2 of the dielectric lens antenna 10 can be melted by heat generated by a heating element. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
