Abstract
Provided is a highly convenient and downsizable terminal device, which realizes, even when more than two contactless information communication units, each utilizing a different frequency band, are mounted on a single IC tag, good communication in each of the different frequency bands. The terminal device has two contactless information communication parts (circuit units, such as an inlay, inlet, chip or the like), which utilizes different frequency bands (for example, the HF band and the UHF band, which is higher than the HF band) performs transmission and reception of signals with two antennae being electric-field-coupled to each other.
Claims16
A contactless information communication terminal device that performs transmission and reception of a signal in a contactless manner with a plurality of communication devices that use different frequencies when performing transmission, comprising:
- a base material;
- a first antenna that is formed on the base material and that transmits and receives a first signal having a first frequency;
- a first processing circuit that is connected to the first antenna and that, when the first signal is received by the first antenna, performs a predetermined first process based on the first signal and that outputs a signal corresponding to the processed results, as a first processed signal, to the first antenna;
- a second antenna that is formed on the base material and that transmits and receives a second signal having a second frequency, which is different from the first frequency;
- and
- a second processing circuit that is connected to the second antenna and that, when the second signal is received by the second antenna, performs a predetermined second process based on the second signal and that outputs a signal corresponding to the processed results, as a second processed signal, to the second antenna, wherein
- the first antenna and the second antenna are isolated from each other and establish electric-field coupling with each other,
- a part of the first antenna and the second antenna are separated with a space therebetween and formed on a first surface of the base material,
- another part of the first antenna is formed on a second surface different from the first surface, and
- the another part of the first antenna and the second antenna establish electric-field coupling via the base material.
