Antenna structure

This work is concerned with the structure of the antenna, in particular an antenna comprising a coupling coil and a dipole.

Radio Frequency Identification (RFID) tags are increasingly commonly used in situations that require non-contact transmission of wireless signals for identification, such as logistics and commodity identification, such as barcode scanning identification systems used in stores.

Generally speaking, a radio frequency identification tag includes a radio frequency chip and a sensing device coupled to it. The radio frequency chip transmits wireless signals and data transmission, thereby generating an identification effect.

As the size of electronic devices decreases, the area on a printed circuit board that configures the electronic components of the electronic device becomes increasingly limited. This restricted area can affect electronic devices that include multiple antennas for multi-band communication with external systems and devices. For example, different antennas can have different layout requirements, and the use of multiple different antennas in a single device can affect the size of the device.

Therefore, the creator of this case came to this creation after observing the above-mentioned deficiencies.
