PURPOSE:To ensure a wide range of band, by providing an antenna element having a variation modulus nearly adverse to the variation modulus between the phase difference among polarized waves of a certain antenna and the frequency to said antenna. CONSTITUTION:An antenna element 33 is attached to the side of a feeding pattern 32 of a feeder 31. The phase difference between polarized waves (d) and (e) that is caused at a circular polarized wave type antenna 31 ha a negative variation modulus to the frequency. On the other hand, the phase difference between the waves (d) and (e) caused to the element 33 has a positive variation modulus to the frequency. These waves are synthesized to obtain a circular polarized wave antenna having the frequency characteristics of a phase difference. |
