A multiple loop antenna particularly suitable for use with an electronic article surveillance security system for detecting the presence of a resonant tag employs first and second shielded twisted loops lying in a common plane and having portions thereof interleaved with each other. The loops are electrically coupled to each other and to a common transmitter or receiver. The loops may be fabricated from coaxial cable to achieve the shielding function at low cost while providing design flexibility.
