Abstract
The invention relates to a high-intermodulation spotlight antenna, and belongs to the technical field of directional antennas. The high-intermodulation spotlight antenna comprises a high-intermodulation directional antenna and a spotlight housing, wherein the spotlight housing comprises a bakelite outer cover, a plastic panel and a plastic buckle for fixing the panel on the outer cover. During operation, the high-intermodulation directional antenna of the high-intermodulation spotlight antenna in a spotlight radiates outward by the panel, as the outer cover is made of bakelite and the buckle of the panel is made of plastic, the radiation influence on the directional antenna is very small, and especially the intermodulation is almost free from influence. The high-intermodulation spotlight antenna can achieve the high-standard requirement that the intermoudulation of high frequency and low frequency is less than -110dB on the premise of ensuring the mechanical and electrical properties of a conventional spotlight antenna.
Description
Technical field
The invention belongs to the directional antenna technique field, relate in particular to a kind of embellished antenna.
Background technology
The torch-type embellished antenna is one of main selection that domestic present residential quarter phasing signal covers and the skyscraper signal covers, and better performances can arbitrarily be adjusted the updip angle; But because the shot-light housing is metal, and the shot-light panel fastener also is metal, and size is not within Antenna Design, it is the housing that uses die sinking on the market, also be consistent for the shot-light with common no signal covering simultaneously, this just causes intermodulation to be subject to the impact of housing and panel fastener, all can only reach-70 to-80dBm at low frequency and high frequency intermodulation, poor effect, for movement, operator of UNICOM the occasion that high standard requires is proposed, the intermodulation index must be qualified, and conventional money spotlight antenna at all can't be up to standard.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of high intermodulation spotlight antenna, this high intermodulation spotlight antenna under the prerequisite of the mechanical performance that guarantees conventional spotlight antenna and electrical property, reach the high and low frequency intermodulation＜-the high standard requirement of 110dBm.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of high intermodulation spotlight antenna comprises high intermodulation directional antenna and shot-light housing, and described shot-light housing comprises bakelite outer cover and plastic front board, and described panel is fixed on plastic buckle on the described outer cover.
During the high intermodulation spotlight antenna work of the present invention, to external radiation, because outer cover is the bakelite material, panel fastener is plastic material to high intermodulation directional antenna at the inner process of shot-light panel, thus very little to the radiation effect of directional antenna, especially on almost not impact of intermodulation.
Description of drawings
Fig. 1 is the high intermodulation spotlight antenna of the present invention housing assembling schematic diagram;
Fig. 2 is the high intermodulation spotlight antenna of the present invention schematic internal view.
Embodiment
Below in conjunction with accompanying drawing the present invention is made and to further specify.
As shown in the figure, the high intermodulation spotlight antenna of the present invention comprises bakelite outer cover 1 and plastic buckle 2, plastic front board 3, high intermodulation directional antenna 4, to external radiation, because outer cover 1 is the bakelite material, panel fastener 2 is plastic materials to high intermodulation directional antenna 4 at the inner process of shot-light panel 3, so the radiation effect to directional antenna is very little, especially on almost not impact of intermodulation.
Conventional shot-light outer cover size 360*340*125mm just in time produces resonance about 900MHz, have a strong impact on the intermodulation index, adopts the shot-light outer cover of bakelite material, and intensity can be guaranteed; Bakelite is radiation signal or all not impacts of intermodulation index on product simultaneously, has guaranteed the high intermodulation performance of product integral body.
Replace conventional metal buckle with plastic front board buckle 2, because metal buckle causes the especially resonance about 1800MHz of high frequency easily, can cause the intermodulation index defective, so use the plastic front board buckle to replace it.Panel 3 usefulness glass cements are fixed on the shot-light housing, both can play waterproof effect, more can make panel and housing tight fit, not loosening, so replace metal buckle intensity fully enough with the plastic front board buckle, effect is almost identical.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (1)
1. one kind high intermodulation spotlight antenna comprises high intermodulation directional antenna and shot-light housing, it is characterized in that: described shot-light housing comprises bakelite outer cover and plastic front board, and described panel is fixed on plastic buckle on the described outer cover.
