Abstract
There is provided a USB cable antenna which also uses a USB cable as an antenna that receives a high-frequency signal in a desired band, by connecting a metal shield of the USB cable to an ID terminal of a USB connector connected to the USB cable of a predetermined length connected to an information terminal device, connecting a high-frequency cutoff element having a high impedance for the high-frequency signal in the desired band to both ends of a power supply line and a ground line of the USB cable, and connecting a common mode choke having the high impedance for the high-frequency signal in the desired band to both ends of a transmission line of a differential signal of the USB cable.
Claims6
A USB cable antenna suitable for acting as both a USB cable and as an antenna for receiving a high-frequency signal in a desired band, the USB cable antenna comprising:
- a metal shield connected to an identification (ID) terminal of a cable-side USB connector connectable to an information terminal device;
- a high-frequency cutoff elements having a high impedance for the high-frequency signal in the desired band and connected to both ends of a power supply line and a ground line of the USB cable;
- and
- common mode chokes having the high impedance for the high-frequency signal in the desired band and connected to both ends of a transmission line of a differential signal of the USB cable.
