Description

Technical Field

[0001] The utility model belongs to the technical field of radar antennas, in particular to an opening and closing device for a cross-loop antenna. Background Art

[0002] The crossed loop antenna is also known as a cross-polarized antenna or a cross antenna. It consists of two half-wavelength (or multiples thereof) dipoles that cross each other perpendicularly. The crossed loop antenna can achieve vertical and horizontal polarized signal reception and transmission. Its construction allows for simultaneous reception and transmission of two mutually orthogonal polarizations (vertical and horizontal) when receiving and transmitting. One of the advantages of the crossed loop antenna is that the frequency response is relatively broadband, it can operate on multiple frequency bands, providing omnidirectional radiation and good radiation. In addition, due to its simple structure and durability, it is widely used in many applications, such as mobile communications, satellite communications, avionics, and RF measurement.

However, when using rigid oscillators, the two ring oscillators are often disassembled and packaged separately to save space during storage and transportation. The entire disassembly and assembly process is time-consuming and labor-intensive, and separate packaging can easily cause device damage or even failure. Utility Model Content

[0045] A vertical monopole antenna 1, also known as a vertical column antenna or a monopole antenna, is a common wireless communication antenna. It is a vertically placed antenna with a single oscillator or radiating element.

[0046] The basic structure of the vertical monopole antenna 1 is usually a vertical straight rod, which is the radiating element of the antenna and is responsible for transmitting and receiving electromagnetic wave signals.

[0054] like Figure 5 As shown, in order to prevent the captive screw 9 from scratching the cross-loop antenna assembly 2, a spring 12 is provided on the captive screw 9. After loosening, the spring 12 will immediately bounce the captive screw 9 away to avoid scratching the cross-loop antenna assembly 2.

[0055] like Figure 6In order to prevent the end of the lower vibrator 7 from sliding out of the sliding groove 8 of the upper vibrator 6 after opening, a limiting sleeve 11 is further provided at the bottom of the upper vibrator 6, which is used to clamp the lower vibrator 7 when opening. In order to facilitate fixation, a second through hole 13 is also provided at the tail end of the lower vibrator 7.
