Abstract
Small, low cost, notch antennas are provided that can be internally incorporated into the existing structure of wireless communicators, and that are functional in a variety of orientations of the wireless communicator. The notch antenna is preferably formed in the ground plane conductor of a printed circuit board (PCB) that has RF circuitry thereon for receiving and transmitting RF signals. The notch preferably has a configuration that results in electromagnetic waves having a substantially omnidirectional radiation pattern being radiated from the notch when RF signals are applied to the notch. Integrating the antenna function into the same printed circuit board (PCB) on which the transmitter and/or receiver functions are also located eliminates the need for an additional antenna component. However, if necessary, a notch antenna surface component is also provided.
