ARRAY ANTENNA AND SECTOR ANTENNA |
摘要 |
This array antenna (100) is provided with: a reflection plate (200); low-frequency-band dipole elements (110-1 to 110-3) arrayed in the vertical direction above the reflection plate (200); high-frequency-band dipole elements (120-1 to 120-6) similarly arrayed in the vertical direction above the reflection plate (200); and conductors (130-1 to 130-4) configured from a conductive material and similarly arrayed in the vertical direction above the reflection plate (200). The low-frequency-band dipole elements (110) and high-frequency-band dipole elements (120) are arrayed in an intermixed manner, and the conductors (130) are disposed at the side of the high-frequency-band dipole elements (120) at which the low-frequency-band dipole elements (110) are not disposed. As a result, in the transmission/reception of radio waves in a plurality of frequency bands, an effect of the transmission/reception of radio waves at one frequency band by an antenna element on the directivity or the like in another frequency band is suppressed. |
