Abstract

See full text

A compact flexible high gain antenna is disclosed which includes a co-planar array of at least three substantially parallel main conducting antenna elements, a reflector, a driven element, and a director. Each of these elements may be terminated on the ends by a stub element, and the reflector and the director may include an intermediate meander element. Stub elements capacitively load the antenna, while meander elements inductively load the antenna, and the loading affects the resonant frequency of the antenna. The conducting antenna elements may be affixed to a flexible dielectric substrate and may be bent or curved into different compact shapes, suitable for fitting manufacturing form factors for a handheld RFID reader. The antenna has a high directional gain which results in a longer operating range.
