Title:
POLARIZED WAVE DIVERSITY SECTOR ANTENNA
Document Type and Number:
Japanese Patent JP2001085938
Kind Code:
A
Abstract:
To obtain a polarized wave diversity sector antenna where the same service can be ensured among horizontally and vertically polarized wave radiation directivity antennas with a simple structure and polarized wave antennas consisting of the antennas.
The horizontally or vertically polarized wave radiation directivity antenna A or B is configured by exciting radiation elements (1), (4) made of a metallic flat plate folded longitudinally or horizontally at a prescribed angle from their rear faces through installation plates (2), (5) by coaxial cables (3), (6) by means of a one-point feeder. These antennas of three pairs (A1 to A3, B1 to B3) are placed vertically to obtain the polarized wave diversity sector antenna.
