Abstract
A sensor to detect information on a subject by using an electromagnetic wave includes a transmitting unit having a generating element and a first antenna, a polarization converting unit, and a receiving unit having a second antenna and a detecting device. The generating element generates an electromagnetic wave, and the first antenna emits the electromagnetic wave generated by the generating element as first polarization. The polarization converting unit converts the first polarization into second polarization by changing a polarization direction of the first polarization. The second antenna receives the second polarization, and the detecting device detects the electromagnetic wave received by the second antenna. The transmitting unit and the receiving unit are disposed on the same substrate.
