Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
In free space, when dipole length is half-wavelength integral multiple, dipole resonance.And in dipole week
When enclosing loaded medium, the resonance length of dipole can be compressed, and the compressed coefficient is defined as K.Known according to dipole basis
Know, for the higher order resonances mode dipole of uncompressed (K ≈ 1), minor lobe is much larger than main lobe, and then leads to dipole main lobe gain
It is lower.After the medium of load high dielectric constant, dipole length is compressed, and main lobe width becomes larger, gain reduction.Therefore,
Conventional dipole sub-antenna is all fundamental resonance and K close to 1.
Sub-antenna of the present invention is the tertiary mode dipole antenna of compressed coefficient K ≈ 2.041 a kind of, as shown in figure 3, basic mode
Current direction is consistent on dipole when resonance, and current direction changes twice when mould resonance three times.Compared to K=1, dipole when K > 1
The length of sub- arm significantly reduces, and the size of dipole antenna also accordingly reduces.With the increase of K value, dipole gain can reach
Peak value, minor lobe constantly reduce.Therefore have chosen a suitable compressed coefficient, i.e. K ≈ 2.041, come obtain lesser minor lobe and
Biggish gain.
In order to match compared with the compressed coefficient, the dipole antenna of load folding line is used.As shown in Figure 1, the present invention compresses
The Sidelobe high-gain mold compression dipole antenna, including linear type dipole 1 three times of the load folding line of COEFFICIENT K ≈ 2.041,
The middle part of the linear type dipole 1 is formed with first group of bending cable architecture 2 being arranged symmetrically, in first group of bending cable architecture
2 outside forms second group of bending cable architecture 3 being arranged symmetrically, and forms 4 bending cable architectures, and bilateral symmetry altogether.By setting
Four bending cable architectures are set, minor lobe is reduced.
As shown in Fig. 2, specifically, first group of bending cable architecture 2 includes the first folding line 52, the second folding line 53, second
Group bending cable architecture 3 includes third folding line 51, the 4th folding line 54, and the total length of four folding lines is dipole arm length
1/6th, the distance between third folding line 51 and the first folding line 52 are a quarter of dipole arm length, electrical length
It is 0.735.
Preferably, first folding line 52,53 structure of the second folding line are identical, and the third folding line the 51, the 4th is curved
54 structure of broken line is identical, S-shaped tendency bending, and after bending folding line two sides relative to linear type dipole 1 be in two sides
The rectangle inside opening structure outwardly protruded, more preferably, the third folding line 51, the outer protrusion of the 4th folding line 54 are high
Degree is a folding line 52, the outer protrusion height of the second folding line 53 less than the first folding line 52, the outer protrusion height of the second folding line 53
A quarter it is high.
As shown in Fig. 2, two symmetric arms of dipole, i.e. the first arm 41, the second arm 42 and four folding lines print respectively
On the microstrip substrate 8 that relative dielectric constant is 11.2, dipole is fed by ladder microstrip line 7 and gradual change floor 6.Compared to not plus
The minor lobe of folding line dipole antenna is carried, minor lobe is down to -16.13dB, gain 5.07dBi. after loading folding line
After loading folding line, gain is 5.07dBi. as shown in figure 4, minor lobe in document [2] is about -3dB, and of the invention
The minor lobe of designed dipole antenna out is -16.13dB, as shown in Figure 5.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
