PROBLEM TO BE SOLVED: To obtain an electric phase difference between antenna elements without a coaxial cable or a phase adjuster, with respect to an antenna for receiving circulary polarized wave. SOLUTION: First and second antenna elements 3a, 3b, 5a and 5b and phase difference lines 7a and 7b are integrally formed of mutually equal materials. Without using the coaxial cable or the phase adjuster, a desired electric phase difference corresponding to a mechanical crossing angle between the first and second antenna elements 3a, 3b, 5a and 5b is obtained and the assembly work of soldering or the like is eliminated as well. |
