Abstract
An antenna () comprises an input port () for feeding an electrical signal, a radiating element () coupled to the input port that radiates energy of the electrical signal, a second port () coupled to the radiating element, a ground structure () coupled to the radiating element and second port; and a negative slope reactance circuit () characterized by a negative slope of reactance versus frequency, coupled to the second port. The antenna has a wideband frequency range relative to a natural bandwidth of the antenna.
