Abstract
A coordinate input device 100 includes a signal generation unit 1, a transmitting antenna unit 2, a receiving antenna 3, and a detection unit 4. The transmitting antenna unit 2 includes a plurality of antennas that transmits an electromagnetic wave W according to an AC signal. The signal generation unit 1 outputs the AC signal SIG to one of the plurality of antennas of the transmitting antenna unit 2. The receiving antenna 3 receives the electromagnetic wave W from the transmitting antenna unit 2. The detection unit 4 obtains an intensity distribution of the electromagnetic wave W corresponding to the positions of a plurality of antennas based on the electromagnetic wave W received by the receiving antenna 3, and detects a detection position according to the position of a peak in the intensity distribution.
