Printed antenna having electrical length greater than physic al length

摘要

A printed antenna (10) is disclosed including a printed circuit board (12) of a specified length and width having a first side (14) and a second side. A radiating element in the form of a conductive trace (18) is formed on one of the printed circuit board sides, with the conductive trace having a physical length from a first end to a second end where an electrical length of the conductive trace is greater than the physical length thereof. The conductive trace has at least a portion with a non-linear pattern (26), which preferably is in the form of a repeating crank or square wave pattern.
