10 the first reflector 13 after bending, brake forming (i.e. radius on cylindrical surface) at a distance from primary antenna 11 preferably exists
Between 0.15 times to 0.5 times (i.e. 0.15 λ to 0.5 λ) of wavelength corresponding to the operating frequency of primary antenna 11, but the present invention not because
This is limited.Furthermore in other embodiments, the position of the second diode 134 and the second capacitance 133 can be interchanged.
Further, the first rectangle locked groove pore structure or the first rectangular slot hole knot are constituted about the first reflector 12
Structure, the first rectangle locked groove pore structure or the first rectangular slot pore structure description below explanation that the second reflector 13 is constituted.With
Primary antenna 11 operates in for 3.5GHz frequency bands, when the first diode 124 and the second diode 134 are all not turned on, radiation field
Type is as shown in Figure 3A, is intended to more uniform omni-directional radiation pattern (being known as pattern zero at this time).It ties in the first rectangle locked groove hole
The long side (in cylindrical surface 103a) of structure is perpendicular to the single polarization direction (namely perpendicular to Z axis), when the first diode
When 124 conducting, the first rectangle locked groove pore structure forms radiation field as shown in Figure 3B as reflector (being known as pattern one at this time)
Type, and it is preferred that the length of the long side of the first rectangle locked groove pore structure is wavelength corresponding to the operating frequency of primary antenna 11
Half.When the first diode 124 is not turned on, the first rectangular slot pore structure is not as reflector, and it is preferred that

Body, therefore whole radiation pattern is influenced, allow the first reflector element 12 to generate the effect of reflection.When the first diode 124 is not led
Logical, for the operating frequency of primary antenna 11, metallic plate 121 and first time metallic plate 122 are to utilize the first capacitance on first
123 are connected each other, so when first on metallic plate 121, first time metallic plate 122 and the first capacitance 123 constitute the first rectangle and open
Slotted hole structure, wherein the position of the first diode 124 is the opening of this grooved bore.Even if primary antenna 11 excites the first rectangle
Electric current in pore structure of slotting, the electric current in the first rectangular slot pore structure do not influence the radiation pattern of primary antenna 11 generally.
Similarly, the long side (in cylindrical surface 103a) of the second rectangle locked groove pore structure perpendicular to the single polarization direction (
Just it is perpendicular to Z axis), when the second diode 134 is connected, the second rectangle locked groove pore structure (is known as mould at this time as reflector
Formula two), radiation pattern as shown in Figure 3 C is formed, and it is preferred that the length of the long side of the second rectangle locked groove pore structure is main
The half of wavelength corresponding to the operating frequency of antenna 11.When the second diode 134 is not turned on, the second rectangular slot hole knot
Structure is not as reflector, and it is preferred that the length of the long side of the second rectangular slot pore structure is the operating frequency of primary antenna 11
Half frequency corresponding to wavelength a quarter.
