Along with the mining ground through communication system of China transmission range to reach km about, traditional antenna can not meet the demands.Traditional beamwidth of antenna is wider, does not effectively suppress out-of-band signal, and when making work, signal to noise ratio is very low, system cisco unity malfunction time Received signal strength is faint.Meanwhile, antenna is owing to being connected with system, and the input resistance of receiving terminal or transmitting terminal is directly loaded on antenna, makes the Q value in antenna self-resonance loop very low, the effective area A of antenna
effless, the small-signal in larger space around antenna can not be gathered near antenna and realize receiving, this makes existing communication system effectively can not receive small-signal.
Therefore, need a kind of new antenna aspects, effectively suppress the ambient noise of non-operating frequency, strengthen the reception of useful signal in operating frequency, solve the key issue that remote through the earth communication does not solve for many years.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Self-resonance formula array antenna embodiment 1
As shown in Figure 1 and Figure 2, a kind of self-resonance formula array antenna, comprises first, second two antenna elements, and each antenna element is made up of an ac circuit and an energized circuit.
For the first antenna element, its ac circuit is a capacitive load coil 105, and coil two ends are connected by a monomer electric capacity 106.Electric capacity adopts low loss capacitance.Coil 105 is circle band shape (or strip) conductor.Energized circuit 107 is located in outside coil 105, forms a conducting ring, and the openend 101 of this conducting ring is connected to the transmitting/receiving port one 03 of ground through communication system 104 through wire.
For the second antenna element, its ac circuit is a capacitive load coil 108, and coil two ends are connected by a monomer electric capacity 109.Electric capacity adopts low loss capacitance.Coil 108 is circle band shape (or strip) conductor.Energized circuit 110 is located in outside coil 108, forms a conducting ring, and the openend 102 of this conducting ring is connected to the transmitting/receiving port one 03 of ground through communication system 104 through wire.
As Fig. 2, port one 01,102 is connected, and is connected after series connection with the transmitting/receiving signal port one 03 of communication system 104.
By regulating the interval (distance namely between coil and energized circuit) of energized circuit and capacitive load coil, the transmitting/receiving port one 03 of the input impedance and ground through communication system 104 that realize port one 01,102 place matches.Wire due to band shape has larger cross section, thus has less resistance relative to thin wire, is conducive to the Q value improving capacitive load coil.In the present embodiment, energized circuit interval is located in outside capacitive load coil, and as other execution modes, as Fig. 3, capacitive load coil is located in outside energized circuit.
In the present embodiment, capacitive load coil 105,108 and energized circuit 107,110 are rectangle, as other execution modes, also can be other shapes, as circle, polygon etc.Capacitive load coil can wear magnetic core.

In the present embodiment, the electric capacity between capacitive load coil two ends is monomer electric capacity, also can be by some monomer capacitances in series, parallel connection, even the capacitance module of connection in series-parallel formation.
Energized circuit is directly connected with the transmitting/receiving end of communication system by wire and forms loop, energized circuit and capacitive load coil close, insulate, by magnetic Field Coupling, realize communication system transmitting end or the power transfer between receiving terminal and capacitive load coil.
Because the bandwidth of operation of single capacitive load coil is narrower, the antenna that therefore individual antenna unit (or operating frequency identical multiple antenna elements) is formed is only applicable to the slower narrow-band communication system of traffic rate.Consider that capacitive load coil that Q value is higher effectively can increase the effective area of antenna, be conducive to strengthening antenna to the reception of small-signal, but less frequency bandwidth can be brought simultaneously to reduce communication channel capacity thus reduce traffic rate.Use the ground through communication system of single antenna, need the capacitive load coil selecting suitable Q value, communication distance and traffic rate are compromised, forms the technical bottleneck of the multimedia communications such as remote voice.In order to address this problem, array antenna technique can be adopted, the bandwidth of broadening antenna.Such as, in the present embodiment, have employed two antenna elements, the capacitive load coil of two antenna elements is set to different frequency, the operating frequency of each capacitive load coil at below 10KHz, to ensure through the earth communication demand; Be coupled with the one or more of energized circuit be connected with communication system transmit-receive end by magnetic field, realize reception or the transmitting of broadband signal.

Energized circuit forms conducting ring, and the conducting ring of three energized circuits has openend 201,202,203 respectively.As Fig. 5, the openend of three energized circuits is in parallel, is connected after parallel connection with the transmitting/receiving signal port 204 of communication system 205.
In the present embodiment, capacitive load coil adopts multiturn wire.Three capacitive load coil working frequencies are not identical, and such as three coils adopt the coil of different geometrical size or the loading capacitance of different capabilities.Because each capacitive load coil has not identical resonance center frequeH, by energized circuit is in parallel, realizing whole antenna array system to have relative to only having the capacitive load coil of an one working frequency to have wider bandwidth, significantly improving the channel capacity of communication system thus improving traffic rate.The Q value high due to wide bandwidth sum is conflict, can not realize on single self-resonance capacitive load coil.In order to possess the multimedia communication functions such as voice, thus there is the requirement of certain communication frequency bandwidth, only having the demand adopting the self-resonance antenna of this array format simultaneously could meet the multimedia communication bandwidth such as the saturating ground Distance geometry voice of ground through communication system.
