ABSTRACT:
A printed monopole antenna is disclosed including a first printed circuit board having a first side and a second side, a first monopole radiating element in the form of a conductive trace formed on a side of the first printed circuit board, and a second monopole radiating element in the form of a conductive trace positioned adjacent the first monopole radiating element, wherein the first monopole radiating element is resonant within a first frequency band and the second monopole radiating element is resonant within a second frequency band. In order for the first and second radiating elements to be resonant within different frequency bands, the conductive traces for each have different electrical lengths. No direct electrical connection exists between the monopole radiating elements, but the second radiating element dominates at a frequency in which the second radiating element is approximately a half-wavelength so that coupling with the first radiating element occurs. The first and second monopole radiating elements are formed on the same side of the first printed circuit board, separate sides of the first printed circuit board, or on separate printed circuit boards.
