Summary:A small, high Q loop antenna configured on a printed circuit board as a planar structure receives a radio signal and shields its interior planar area against interfering electric field energy while concentrating therein radio signal magnetic flux. A magnetic pickup loop, coplanar to the antenna loop and magnetically coupled thereto, receives the radio signal power by virtue of its magnetic coupling to the loop antenna. The magnetic pickup loop couples to a receiving device and delivers the radio signal thereto. Illustrated embodiments include loop antennas tunable to a desired resonant frequency.
