摘要： PURPOSE:To provide a small-sized, light-weight and inexpensive antenna for responding to both horizontal polarized waves and vertical polarized waves by arranging the third antenna element of a dipole type so as to orthogonally cross with first and second antenna elements parallelly arranged with a specified interval and connecting it to the first and second antenna elements. CONSTITUTION:When power is fed from the center of the antenna element 13 of a dipole type while the antenna elements 11 and 12 arranged with the interval of 0.1-0.75lambda and provided with the electric length of less than lambda/2 are extended at the time of defining the wavelength of a using frequency band as lambda, the elements 11 and 12 connected to both ends of the element 13 are also turned to radiation elements and the vertical polarized waves are radiated. Also, the element 13 is operated as the antenna element of the horizontal polarized waves. Thus, when the elements 11 and 12 are extended, both vertical and horizontal polarized waves are responded to. On the other hand, when the elements 11 and 12 are housed, the element 13 mainly radiates radio waves. Thus, this antenna suitable for personal handy phone system (PHS) handy antenna is obtained.
