Abstract
An antenna comprising: (a) a conductive ground plane; and (b) a rod shaped monopole element having a conductive surface, oriented out from the ground plane and having a length selected for a first radio frequency band, the monopole element having a current suppressing element conductively attached and surrounding the surface of the monopole element at a location on the monopole element determined by a second frequency band higher than the first frequency band. The rod-shaped monopole element has a relatively wide cross-section such that the antenna is operable over relatively wide ranges of frequencies in one or both of the frequency bands. The antenna is for operation in the 2.4 GHz and the 5 GHz bands as used in the IEEE 802.11standards.
