=1.6mm.As shown in Figure 1.
Fig. 2 is the S11 characteristic curve of the example of the utility model, and -10dB frequency bandwidth is 6.2~8.6GHz, frequency band depth
For -26dB.
Fig. 3 is the VSWR characteristic curve of the example of the utility model, and the frequency bandwidth of VSWR≤5 is 6.25~8.4GHz.
Fig. 4 is the directional diagram of the example of the utility model, which is able to achieve directed radiation, and highest-gain reaches
To 1.2dB.
The foregoing is merely the most preferred embodiments of the utility model, are not intended to limit the utility model, all at this
Any modifications, equivalent replacements, and improvements done within the spirit and principle of utility model, should be included in the utility model
Within protection scope.
