Description

Antenna reflecting plate structure for wireless communication system and antenna
Technical Field
The present invention relates to wireless communication technology, and in particular, to an antenna reflector structure for a wireless communication system and a corresponding antenna for a wireless communication system.
Background
Generally, the radiating platform of an antenna comprises a reflector plate, an element, a baffle plate, and the baffle plate functions to improve radio frequency characteristic parameters of the antenna, such as lobe width, isolation, and cross-polarization. Generally, plastic spikes will be used to secure the baffle to the reflector, however, the number of spikes depends on the length of the baffle and the securing requirements, and in particular, an insulating film (such as a spacer tape) may need to be added between the contact areas of the baffle and the reflector to avoid direct contact between such two parts, resulting in Passive Inter Modulation (PIM), and fig. 1 shows a schematic diagram 100 of one such exemplary antenna reflector structure with an insulating film added between the contact areas of the baffle and the reflector. As shown in fig. 1, an insulating film 130 is isolated between the baffle plate 110 and the reflection plate 120, and these three are fixed by a plastic spike 140, and the antenna structure further includes an oscillator 150.
As can be inferred from fig. 1, firstly the cost of such a structure is high, due to the high material costs (e.g. the need for an additional insulating film 130); in addition, the assembly of such a reflection plate structure 100 will also consume a lot of time, since the insulating film 130 must be uniformly laid between the baffle 110 and the reflection plate 120, and such an assembly process is necessarily time-consuming.
The effect of adding baffles is to improve the radio frequency characteristics parameters of the antenna, such as lobe width, isolation and cross-polarization, which is a simple approach, but the structure shown in fig. 1 risks the following:
first, the uncertainty of flattening the insulating film 130 necessarily results in non-uniform distances between the baffle 110 and the reflector 120, especially with viscous material on one or both sides, which can lead to passive intermodulation problems.
Secondly, there may be some non-flat or non-smooth areas on the surface of the baffle 110 or the reflector 120, and there may be burrs that may cause poor contact and may pierce the insulating film 130, thereby causing a more serious problem of passive intermodulation.
Furthermore, poor locations of the insulating film 130, such as non-uniform laying of the insulating film, will result in bad plastic contacts and thus passive intermodulation problems.
Finally, adhering the insulating film 130 and assembling the baffle 110 to the reflector 120 using the nails 140 also requires a lot of labor and time for installation.
