Embodiment approach 1
[0038] Embodiment 1, the low-frequency radiating unit A includes two sets of orthogonal linear half-wave oscillators 102 and a feed support device. The feed support device is a balanced balun 101, which includes two sets of metal plates that are parallel to each other and short-circuited at the bottom. Cylinder, the height of which is a quarter of the operating wavelength. The half-wave vibrator 102 includes a vibrator arm 1021 connected to the feed support device, and the free end of the vibrator arm is bent downward at an angle of 90 degrees to form a space loading section 102 .
[0039] The high-frequency radiation unit B includes two sets of orthogonal planar half-wave oscillators 103 and a feed support device, the feed support device is a balanced balun 101, which includes two sets of metal cylinders parallel to each other and short-circuited at the bottom, Its height is a quarter of the operating wavelength. The vibrator arms 1031 of the planar half-wave vibrator are sq...
