PROBLEM TO BE SOLVED: To provide an antenna of high load resistance performance by using a material of high marketability which is used in general. SOLUTION: An arm 1 is arranged in a center with respect to the direction of transmission and reception and respective elements such as a wave guiding element 2, a radiation element 3, a reflective element 4 are supported at intervals of aboutλ/4 by a supporting member 5 in a form orthogonal to the arm 1. The element 3 is fixed to the arm 1 by a feeding part 6 used in common as a supporting part. In addition, a jack 8 for a coaxial is connected to the part 6 through a trap circuit 7. Then, auxiliary elements 11 whose electric lengths are shorter than the element 2 and the element 4 are provided at the element 2 and the element 4. These elements 11 are supported to the arm 1 by a supporting member 12 and their tip parts are respectively fixed to the element 2 and the element 4 with connecting hardwares 13. The load resistance of the element 2 and the element 4 is increased by providing the supporting elements 11.
