Abstract

To ensure communication performance of an antenna with a reduced antenna size, while maintaining operation performance of a touch pad. Disclosed is a touch pad antenna device (100), which is provided along with a capacitance type touch pad (10) mounted in an electronic apparatus (1), and which communicates with an external apparatus by means of electromagnetic field signals. The touch pad antenna device is provided with an antenna coil (102) wherein conducting wires (102a) facing each other in the width direction with an opening (103) therebetween are provided by being wound such that the conducting wires are close to each other, said antenna coil being inductively coupled to the external apparatus, and the antenna coil is provided along an outer end (38a) of a sheet-like electrode section (38) that constitutes the touch pad.

Description

technical field [0001] The present invention relates to an antenna device for a touch panel in which a capacitive touch panel mounted on electronic equipment such as a notebook computer and an RFID antenna are integrated, and electronic equipment incorporating the antenna device for a touch panel. This application claims priority based on Japanese Patent Application No. Japanese Patent Application No. 2015-024201 for which it applied in Japan on February 10, 2015, and takes in this application by referring to this application. Background technique [0002] In recent years, technology has been developed to equip electronic devices such as notebook computers with antenna functions such as RFID (radiofrequency identification) to enable communication with external devices such as smartphones. However, in notebook computers that are being reduced in size and thickness, the casings are often made of metal, which shields radio waves, making it difficult to ensure the communication ...
