Embodiment
The antenna structure that can do the balance binding with the reception system that this is novel, as shown in Figure 1, system is connected to feed side assembly 40 with symmetry or asymmetric pattern through transmission line 30 with at least two group antennas 10,20, be connected to system end 50 through feed side assembly 40 again, wherein, this feed side assembly 40 is to select balun (Balun) or choking winding (choke) for use.
Fig. 2 fastens the equivalent circuit diagram of stating formation, and as shown in the figure, after antenna 10,20 distinctly was connected to feed side assembly 40 from both sides respectively, feed side assembly 40 connected a line 11 to earth connection, and was connected to system with another line 21.
Above-mentioned formation, be rain termination electrode with rain unipole antenna 10,20 be considered as that positive input terminal and negative input end constitute differential right, determine the length and the Antenna Design type of transmission line according to the phase settings of the difference of frequency or feed side assembly 50.Receive simultaneously from two phase place by feed side assembly 40 and to differ the main signal and fainter noise wave source that 180 ° and amplitude equate, fainter noise wave source can be cancelled, so the adjustable more low noise signal source that solves.
The antenna structure that can do the balance binding with the reception system that this is novel, the balanced type antenna structure of its formation can not only be avoided penetrating because of the width of cloth that unbalanced antenna produces, and can weaken noise intensity.
The antenna structure that can do the balance binding with the reception system that this is novel, the quantity of its antenna can be even number or odd number, and the quantity of feed side assembly also can be one or more.
The antenna structure that can do the balance binding with the reception system that this is novel can have following several execution modes during enforcement:
