Abstract
The utility model provides a television antenna which comprises the following components: a substrate, a metal antenna which is arranged on the substrate, a capacitor plate which is adhibited on the metal antenna, a metal antenna which is connected with the metal antenna, and a conductor which is connected with the metal antenna. The television antenna provided by the utility model has advantages of compact structure, small thickness and small size. The television antenna can be placed at any indoor place without signal receiving/transmitting performance deterioration.
Description
Technical field
The utility model relates to a kind of television antenna, is specifically related to a kind of light and thin type television antenna.
Background technology
Television antenna (antenna) is a kind of converter, and it is transformed into the guided wave of transmission above-the-line promotion the electromagnetic wave of propagating in unbounded medium (normally free space), or carries out contrary conversion.In wireless device, be used for transmitting or receive electromagnetic parts.The engineering systems such as radio communication, broadcast, TV, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, every electromagnetic wave that utilizes carrys out transmission of information, all relies on television antenna to carry out work.In addition,, aspect electromagnetic wave transmission energy, the energy emission of non-signal also needs television antenna.General television antenna all has invertibity, and same secondary television antenna both can be used as launching television antenna, also can be used as receiving television antenna.Same television antenna is identical as the fundamental characteristics parameter of transmitting or reception.
Television antenna profile has a variety of at present, such as Yagi spark gap television antenna, type television antenna, annular television antenna etc., the volume of the television antenna of these shapes generally can be larger, because of television antenna, comprise radiating portion and guide part into again, radiating portion also has the reflector of being called, and reflector on existing television antenna is less, so receiving sensitivity is lower, guide part into and also have title director, director on existing television antenna is also less, so it is lower to gain, and be substantially all to have produced television antenna accessory and then assemble now, disposable completing not, so speed of production is slow and consistency is poor.And existing television antenna is bulky, be located in addition and indoorly often can not well receive signal, therefore often to be placed in outdoorly, installation, maintenance is loaded down with trivial details.
Utility model content
The problem that the utility model exists for above-mentioned prior art makes improvements, be that the technical problems to be solved in the utility model is to provide a kind of television antenna, this television antenna compact conformation, frivolous small and exquisite, can arbitrarily be placed in the indoor transmitting-receiving that affects Anywhere and not signal.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A television antenna, comprises substrate, is located at metal antenna on substrate, pastes the capacitance sheet on metal television antenna, the wire coil being connected with metal antenna, the wire that is connected with metal antenna.
As an embodiment of the present utility model, described substrate comprises first substrate, second substrate, described metal antenna is located between described first substrate and described second substrate, use substrate that metal antenna is encapsulated in to inside, reduced metal antenna because of the suffered impact of external environment, and substrate can print various patterns, elegant in appearance.
As an embodiment of the present utility model, it is symmetry axis that described metal antenna be take the longitudinal axis center line of described substrate, and the area of described metal antenna the right and left equates.This arranges has simulated the symmetrical design of traditional antenna, can not only realize the effect of traditional antenna, has more improved sensitivity.
As an embodiment of the present utility model, described metal antenna is Copper Foil.The electric conductivity of copper is good, copper sheet is sheared to the pattern that is bent into both sides volume symmetry, substitutes the symmetrical mast of traditional antenna two, has greatly saved resource, has reduced the volume of antenna.
As an embodiment of the present utility model, described wire coil is copper wire.Copper wire coil and described capacitance sheet form induced electromotive force, can in time signal be passed to subscriber equipment.
As an embodiment of the present utility model, also comprise geometrical clamp, base unit, described geometrical clamp is located on described substrate, and described geometrical clamp is connected with described base unit.The setting of described base unit, can be placed on the furniture such as desk, cabinet for TV television antenna described in the utility model stably, light and beautiful, and not only can be used as television antenna can also be as house ornament.
As an embodiment of the present utility model, described base unit comprises pedestal, connecting rod, and described pedestal comprises connecting portion, and described connecting rod one end is inserted on the connecting portion of described pedestal, and the other end is connected with described geometrical clamp.This is arranged so that described base unit can dismantle, when described base unit damages, only need to change one new, or the base unit of also can dismantling when user does not want to put.
The utility model has the advantage of metal antenna is directly sticked on substrate, greatly reduced the volume of television antenna, strengthen the sensitivity of antenna, made television antenna no longer need to be set up in outdoor, and can arbitraryly be positioned over indoor any corner; Substrate is common PVC plate, with low cost, is suitable for large-scale production.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the schematic diagram of the television antenna of a kind of execution mode of the utility model;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is Fig. 1 substrate schematic internal view.
Embodiment
As Figure 1-3, the utility model discloses a kind of television antenna, comprises substrate 1, is located at metal antenna 11 on substrate 1, pastes the capacitance sheet 13 on metal antenna, the wire coil 12 being connected with metal antenna 11, the wire 4 that is connected with metal antenna 11.Capacitance sheet 13 is a slice circular arc-shaped metal sheet, pastes on metal antenna 11, is arranged at the place mutually close with wire coil 12, forms LC oscillating circuit, realizes filtering, and the signal that makes to pass to the equipment being connected is more accurate.
It is symmetry axis that metal antenna 11 be take the longitudinal axis center line of substrate 1, and the area of metal antenna 11 the right and lefts equates.This arranges has simulated the symmetrical design of traditional antenna, can not only realize the effect of traditional antenna, has more improved sensitivity.
In the present embodiment, metal antenna 11 is Copper Foil.The electric conductivity of copper is good, copper foil shearing is bent into the pattern of both sides volume symmetry, substitutes the symmetrical mast of traditional antenna two, has greatly saved resource, has reduced the volume of antenna.
