摘要
An antenna consisting of a thin strip bent-wire monopole disposed on an artificial magnetic conductor (AMC) is loaded at the end opposite to the feed point with a distributed or lumped capacitance to achieve an electrically small antenna for use in handheld wireless devices. The capacitive load reduces the length of the antenna to smaller than one-quarter of a wavelength at a given frequency of operation without suffering a substantial loss of efficiency. This results in an easier integration into portable devices, greater radiation efficiency than other loaded antenna approaches and longer battery life in portable devices, and lower cost than use of a chip inductor.
