Abstract
The invention discloses a slot antenna. The slot antenna comprises a quadrangle metal base plate, a circular gap is formed in the metal base plate by using the center point of the metal base plate as the center of a circle, a bar-shaped gap is further formed in the bottom edge of the metal base plate, and the bar-shaped gap vertically extends to the circular gap from the bottom edge of the metal base plate and is communicated with the circular gap. L-shaped gaps are further symmetrically formed in the two side edges of the metal base plate by using the central axis of the metal base plate as a symmetric line. The L-shaped gaps enable the metal base plate to be provided with two bar-shaped side edges, and the length of the two bar-shaped side edges is smaller than the length of the metal base plate. A bar-shaped edge is formed in the bar-shaped gap, and the bar-shaped edge extends towards the inside of the circular gap from the bottom edge of the bar-shaped gap and stretches into the circular gap. An oval metal plate is further arranged at the top end of the bar-shaped edge. The center of the oval metal plate and the center of the circle of the circular gap are located on the same straight line. According to the slot antenna, the pattern and the size of the slot antenna are specifically designed, and thus the slot antenna can receive electromagnetic waves at the UHF and VHF frequency bands at the same time.
Description
Technical field
The present invention relates to antenna technical field, particularly relate to one and can receive VHF, UHF or the electromagnetic slot antenna of other frequency ranges.
Background technology
The television channel of current use has UHF and VHF two kinds, and the two frequency is not overlapping, selects antenna system again after therefore generally needing selected television channel.For this reason, a kind of slot antenna that simultaneously can receive UHF and VHF frequency electromagnetic need be provided.
Existing multiband slot antenna; such as publication number is the Chinese patent " a kind of multiband back cavity type half module substrate integrated wave guide bent slit antenna " of CN103840271A; it, by designing two metal layers and forming plated-through hole to form resonant cavity between two metal layers, reaches the effect of multiband and reduces antenna size.But above-mentioned slot antenna thickness is thicker and the performances such as antenna standing wave, gain are not good, and can not determine whether it can be applied to UHF and VHF two frequency ranges.
Summary of the invention
Technical problem to be solved by this invention is, for the above-mentioned deficiency of prior art, proposes a kind of slot antenna that simultaneously can receive UHF and VHF two frequency ranges.
The technical scheme that the present invention solves the employing of its technical problem is, a kind of slot antenna is proposed, it comprises quadrangle metal base plate, on described metal base plate with its central point for the center of circle forms circular void, described metal base plate base is also formed with strip crevice, and described strip crevice extends to circular void by metal base plate base vertical and is communicated with circular void; Described metal base plate dual-side is also formed with its central axis for line of symmetry symmetrically arranged L shape gap; Described L shape gap makes metal base plate have two bar shaped sides, and described two bar shaped side edge length are less than metal base plate length; Be formed with bar shaped limit in described strip crevice, described bar shaped limit is extended by strip crevice base and stretches in circular void in circular void; Top, described bar shaped limit is also provided with oval metallic plate; Described oval metallic plate center and the circular void center of circle are positioned at same straight line.
Further, described metal base plate, oval metal plate and bar shaped limit thickness are 0.2-0.5 millimeter.
Further, described metal base plate length is 210-230 millimeter, and width is 190-210 millimeter.
Further, described circular void diameter is 150-180 millimeter, and described strip crevice length is 15-18 millimeter, and width is 21-25 millimeter.
Further, described bar shaped side edge length is 140-150 millimeter, width 8-12 millimeter; Described L shape gap width is 8-12 millimeter, and base, described L shape gap gap length is 40-50 millimeter.
Further, described bar shaped edge lengths 20-22 millimeter, width 16-20 millimeter.
Further, described oval metallic plate long axis length is 100-110 millimeter, and minor axis length is 80-90 millimeter.
The present invention makes slot antenna of the present invention can not only receive the electromagnetic wave of UHF and VHF frequency range by the pattern of specific design slot antenna and size simultaneously, and all has good performance at VHF and uhf band.
Accompanying drawing explanation
Fig. 1 is the structural representation of slot antenna of the present invention;
Fig. 2 is slot antenna standing wave test result figure of the present invention.
Embodiment
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
Please refer to Fig. 1, the invention provides a kind of slot antenna, it comprises: quadrangle metal base plate 10, on described metal base plate with its central point for the center of circle formed circular void 100, described metal base plate base is also formed with strip crevice 200, and described strip crevice 200 extends to circular void 100 by metal base plate base vertical and is communicated with circular void 100.
Described metal base plate dual-side is also formed with its central axis for line of symmetry symmetrically arranged L shape gap 300; Described L shape gap 300 makes metal base plate 10 have two bar shaped sides 20, and described two bar shaped side 20 length are less than metal base plate length.
Be formed with bar shaped limit 30 in described strip crevice 200, described bar shaped limit 30 is extended by strip crevice base and stretches in circular void in circular void 100; Top, described bar shaped limit is also provided with oval metallic plate 40; Described oval metallic plate center and the circular void center of circle are positioned at same straight line.
After adopting said structure, according to electromagnetic radiation theory, the electromagnetic wave modulation that this antenna receives can be become the electromagnetic wave simultaneously meeting UHF and VHF frequency range by.
For further improving slot antenna of the present invention at the gain of UHF and VHF frequency range and standing wave, in the present invention, the concrete size range of gap and metal edges can adopt following parameter:
