<p><P>PROBLEM TO BE SOLVED: To provide a touch panel that can suppress increase in size, reduce attenuation of radiant electromagnetic waves and produce a sufficient gain, and an input device and electronic apparatus having the same. <P>SOLUTION: Two layers of films 1 and 4 are opposed with a given clearance in between, and transparent electrodes 2 and 3 are formed on the opposed surfaces of the films 1 and 4 respectively. The transparent electrode 2 has a stub 5 for receiving and outputting a given high-frequency wave while ensuring impedance matching. The stub 5 can output a potential difference generated by a user's press. The transparent electrode 3 is grounded via a capacitor C1 for creating a high-frequency low potential. The two layers of transparent electrodes 2 and 3 not only function as resistive films for generating a potential difference from which an input is detected, but also function as micro strip type planar antennas. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
