摘要： A disk-shaped conductor 22, a ring-shaped conductor 24 and a ring-shaped conductor 26 are arranged in that order on the same plane. One end of a linear conductor 21 is connected perpendicularly to the center of the disk-shaped conductor 22, and the outer edge of the disk-shaped conductor 22 is connected to the inner edge of the ring-shaped conductor 24 via an anti-resonance circuit 23. Moreover, the outer edge of the ring-shaped conductor 24 is connected to the inner edge of the ring-shaped conductor 26 via an anti-resonance circuit 25. Due to the anti-resonance circuits 23 and 25, electrical blocking can be attained, so that an electromagnetic wave of a first frequency f1 is excited by the system extending from the linear conductor 21 to the disk-shaped conductor 22, an electromagnetic wave of a second frequency f2 is excited by the system extending from the linear conductor 21 to the ring-shaped conductor 24, and an electromagnetic wave of a third frequency f3 is excited by the system extending from the linear conductor 21 to the ring-shaped conductor 26. Thus, a small monopole antenna can be attained that has a simple structure and can be operated at a plurality of frequencies.

摘要： Although conventional antennas have characteristics suitable for mobile radio base stations, their vertical dimension is large, and locations of their installation are limited. A radiator for an first upper antenna 32 is arranged in a hollow nonconductive radome 2, using an internal conductor 7a and a metal pipe 10. A radiator for a second lower antenna 34 is arranged in the radome 2, using metal pipes 14 and 15. Two parasitic elements 31 are installed substantially in parallel with the first antenna 32 below a feeding point 9. Two parasitic elements 33 are installed substantially in parallel with the second antenna 34 above a feeding point 13. These allow the tilt angle to be freely set between -10.degree. and +10.degree. by adjusting the parasitic element length and the antenna to be reduced in size.
