Abstract
The utility model relates to a yagi antenna of the printed circuit board, which is characterized in that: the oscillator of the antenna is the thin copper face of the printed circuit board; the equivalent length corresponds to the wavelength of the wideband electromagnetic wave signal that needs to be received; the element antenna generates syntony and radiates electromagnetic wave; one end of the printed circuit board is connected with a communicating device through the current feed. The utility model has the advantages of metal materials saving, high assembly precision, stable performance, light weight, and low cost.
Description
Technical field
The utility model is a kind of printed circuit board (PCB) Yagi spark gap (being the Yagi spark gap battle array again) antenna, particularly a kind of main element antenna in 1/2 or 3/8 or 5/8 wavelength generation resonance that is suitable for mobile communication system
Background technology
At present, the Yagi antenna of the usefulness that is used to communicate by letter mostly adopts half-wave dipole, or folded dipole.Wherein, the most frequently used is the Yagi spark gap array antenna, and these oscillators need be used metal catheter, and for example copper pipe, aluminum pipe, aluminium-alloy pipe not only consume a large amount of tubing, but also need process metal material, thereby cost is higher.In order to adapt to large-scale production, save resource, reduce cost, improve precision, be necessary to provide a kind of novel element antenna.
Summary of the invention
The purpose of this utility model is to provide a kind of printed circuit board (PCB) Yagi antenna, and this antenna is produced in batches easily, saves resource, and cost is low, and precision height, performance are good.
For achieving the above object, the utility model is taked following design:
A kind of printed circuit board (PCB) Yagi antenna, it is characterized in that: the oscillator of described antenna is the copper sake of printed circuit board (PCB), its equivalent length is corresponding with the wavelength that needs reception wideband electromagnetic ripple signal, element antenna produces resonance, width of cloth radio magnetic wave, an end of described printed circuit board (PCB) is connected to communication equipment by current feed.
1/2 wavelength of described equivalent length and electromagnetic wave signal or 3/8 wavelength or 5/8 wavelength produce resonance.
Connect 1/4 a wavelength microstrip line as short-circuit protection also in parallel on the contact of current feed line on the described printed circuit board (PCB).
The utility model has the advantages that: save metal material, the assembly precision height, stable performance, in light weight, cost is low.
