Abstract
A novel signal receiving antenna comprises a substrate provided with at least one half wave vibrator, an input end of the half wave vibrator is connected with feed-in signal wire, the half wave vibrators have four, a large-side arrow half wave vibrator and a small-side arrow half wave vibrator are adjacent and connected at output ends, and the other large-side arrow half wave vibrator and the other small-side arrow half wave vibrator are adjacent and connected at the output ends. The novel signal receiving antenna has the advantages that four symmetric half wave vibrators form circular polarization so as to increase receiving and transmitting strength of an electromagnetic field in vertical directions of the four vibrators, and signal gain can be over 5dBi according to practice, around one quarter of the wavelength on two sides of an arrow of a large-arrow half wave vibrator forms a right circular polarization to lead the magnetic field to be strongest in front of the antenna substrate, around one quarter on each side of a copper side routing (from a small arrow to a large arrow) has strongest radiation, radio-frequency signals match best when the antenna is in 902-928MHz and 50 Ohm, and consumption can be smallest.
Description
Technical field

Background technology
Along with popularizing gradually that radio frequency identification system technology (RFID) is used, make the object identification quicker also safer.Carry for the convenience of the users or use, the compact main designer trends that become the hand-held data collection device, so antenna applications is on this product the time, one of major issue when its size becomes designing antenna.Although the volume that existing hand-held data collection device antenna has is less, its operation frequency range is very narrow, and electric wave causes data acquisition unit receiving and transmitting signal insufficient strength to emission all around, and loss is excessive, the message pick-up weak effect.
The utility model content
The purpose of this utility model is the deficiency that exists at existing hand-held data collection device structure, provides the structure of hand-hold type data acquisition unit antenna is improved, and it is little to make it reach volume, and signal gain is strong, a kind of novel signal reception antenna that loss is little.
The utility model is achieved in that a kind of novel signal reception antenna, comprises a substrate, and described substrate is provided with at least one half-wave dipole, and the output of half-wave dipole is connected with the feed-in signal line.
Described half-wave dipole is provided with four, is made up of two big limit arrow half-wave dipoles and two little limit arrow half-wave dipoles, and two big limit arrow half-wave dipoles and two little limit arrow half-wave dipoles are that the center is symmetrical arranged,
Described adjacent big limit arrow half-wave dipole is connected at output with little limit arrow half-wave dipole, and two other adjacent big limit arrow half-wave dipole is connected at output with little limit arrow half-wave dipole.
Spacing between the described output is 3.8mm--4.5mm.
The both sides of described little limit arrow half-wave dipole are 2/3 of big limit arrow half-wave dipole two edge lengths.
Described big limit arrow half-wave dipole two edge lengths are 35.2mm--36.2mm, and the both sides of big limit arrow half-wave dipole and the both sides spacing of little limit arrow half-wave dipole are 5.4mm-6.2mm.
The distance of the outer ledge of the conductor on described two big limit arrow half-wave dipoles and arrow half-wave dipole arrow both sides, two little limits and the outer ledge of substrate is 0.8mm--1.2mm.
The size of described substrate can (62mm--72mm) * (62mm--72mm).
Compared with prior art, a kind of novel signal reception antenna that the utility model provides has following advantage: the half-wave dipole of four symmetries forms circular polarization, can reach the above signal gain of 5dBi to strengthen the transmit-receive intensity of electromagnetic field, facts have proved four oscillator vertical direction; The wavelength on big arrow half-wave dipole arrow both sides about 1/4 forms right circular polarization makes magnetic field the strongest in the place ahead of antenna substrate; About 1/4 wavelength of every limit copper bound cabling (from the extremely big arrow of small arrow) is that radiation is the strongest, and antenna radiofrequency signal coupling when 902～928MHz and 50 Europe is best, the loss minimum.
