Ultrahigh frequency electronic label antenna for bottle cap

Abstract

An ultrahigh frequency electronic label antenna for a bottle cap comprises a first antenna arm and a second antenna arm, which are parallel to each other, wherein one ends of the first antenna arm and the second antenna arm are respectively connected with one ends of a third semicircular ring-shaped antenna arm and a fourth semicircular ring-shaped antenna arm, which are symmetric to each other relative to a circle center; the other end of the third antenna arm is connected with a fifth antenna arm; the other end of the fourth antenna arm is connected with a sixth antenna arm; and the other ends of the first antenna arm and the second antenna arm are respectively connected with two pins of an electronic chip. According to the invention, an ultrahigh frequency electronic label is destroyed once being torn and cannot be recycled and reused, so that anti-transfer and anti-counterfeiting purposes of the label are achieved.

Description

technical field [0001] The invention relates to antenna technology, in particular to an ultra-high frequency electronic label antenna for bottle caps. Background technique [0002] In recent years, automatic identification technology has been rapidly popularized and promoted in production, logistics, service and other fields. [0003] Barcode technology, which caused a revolution in the field of identification systems a few years ago, has been widely used. With the deepening of application, barcode technology can no longer meet people's needs in more and more cases due to its own defects, such as small storage capacity, inability to rewrite, and short recognition distance. [0004] RFID (Radio Frequency Identification) is a rapid identification technology that has developed rapidly in recent years. RFID is a non-contact automatic identification technology that automatically identifies target objects through radio frequency signals and obtains relevant data. The identific...

Problems solved by technology

[0008] For ordinary tags, if the chip is placed at one end of the antenna, since the equivalent currents of the two radiating arms of the antenna are equal in magnitude and reversed, canceling each other out, there is basically no radiated energy, that is, the performance of the electronic tag is very poor and cannot be read.
