Description
Technical field

In general, electronic installation receives and transmitted signal all is to see through antenna to operate.In order to reach the design of microminiaturization and concealed antenna, electronic installation uses unipole antenna (monopole antenna) or planar inverted-f antenna (planar inverted F antenna) mostly.Chief reason is that the basic mode attitude of these two kinds of antennas (fundamental mode) all resonates in quarter-wave, so have the advantage of minification.
In addition, electronic installation also can adopt the design of cycle antenna (loop antenna).Chief reason is that cycle antenna has some advantage, such as the cycle antenna of balanced type feed-in can reduce the excitation current on the metal covering, so that antenna is subjected to the impact of environment and metal covering less.Or cycle antenna can reduce its shared area through repeatedly bending, and then is applied on the electronic installation.Below will narrate the application principle of cycle antenna, and with energy transmissible viewpoint whether, whether the mode of cycle antenna can be excited.
Fig. 1 is cycle antenna in the CURRENT DISTRIBUTION schematic diagram of the long mode of all-wave, and wherein cycle antenna 110 is the paths that utilize the coaxial line of 50 Ω (coaxial cable) 120 to transmit as signal.With reference to Fig. 1, follow the direction of arrow, namely the sense of current on the cycle antenna 110 can find to have on the cycle antenna two current zero Z1 and Z2.In addition, the electric current of the inner wire 121 of the coaxial line 120 of flowing through is to flow out coaxial line 120, and the electric current of its outer conductor 122 of flowing through is to flow into coaxial line 120, that is the current opposite in direction of flow through inner wire 121 and outer conductor 122.This opposite sense of current meets the mode of transmission line energy, so coaxial line 120 can transmit its energy on the cycle antenna 110, and then inspires the long resonance mode of all-wave.
Moreover Fig. 2 illustrates and is the CURRENT DISTRIBUTION schematic diagram of cycle antenna in half-wavelength mode, and wherein cycle antenna 210 is the paths that utilize the coaxial line of 50 Ω (coaxial cable) 220 to transmit as signal.With reference to Fig. 2, follow the direction of arrow, namely the sense of current on the cycle antenna 210 can find to only have a current zero Z21 on the cycle antenna 210.In addition, the electric current of the inner wire 221 of the coaxial line 220 of flowing through is to flow out coaxial line 220, and the electric current of its outer conductor 222 of flowing through also is to flow out coaxial line 220, that is the inner wire 221 of flowing through is identical with the sense of current of outer conductor 222.This identical sense of current is violated the mode of transmission line energy.So coaxial line 220 can not transmit its energy on the cycle antenna 210, that is can't inspire the resonance mode of half-wavelength.
In sum, cycle antenna generally operates in the long resonance mode of all-wave, and the cycle antenna of this moment more easily reaches the impedance matching of 50 Ω and has better radiation efficiency.Yet also because cycle antenna adopts the long operation of all-wave, so electronic installation must spend huge hardware space and disposes antenna.In other words, utilize cycle antenna to receive and dispatch the electronic installation of electromagnetic signal, often must need expend more hardware space, and then limited the design of electronic installation in microminiaturization.
