Abstract: The invention provides a multi-band antenna structure for use in a wireless communication system. The antenna structure includes integrated inductive elements and capacitive elements that function as a tuned circuit to allow the antenna structure to operate in multiple frequency ranges. In particular, the capacitive elements electromagnetically couple to the inductive elements. The capacitive elements provide the inductive elements with parallel capacitance at a given set of frequencies, thereby providing the antenna structure with frequency selectivity. At a particular frequency range, the inductive elements act as short circuits, thereby lengthening the radiating elements, which radiate energy at the particular frequency. At another frequency range, the inductive components act as open circuits, virtually shortening the radiating elements in order to radiate the higher frequencies. In this manner, the multi-band antenna structure operates within multiple frequency ranges.

Abstract: The invention provides a multi-layer antenna structure for use in a wireless communication system. The antenna may be integrated within a multi-layer circuit structure such as a multi-layer printed circuit board. The multi-layer antenna structure may include, for example, a radiating component and a conductive strip feed-line that electromagnetically couples to the radiating component to directly feed the radiating component. The conductive strip feed-line may be fabricated to form a balun. The conductive strip feed-line may, for example, form a quarter-wavelength open circuit in order to realize the balun. The balun may perform signal transformations, e.g., unbalanced to balanced, as well as impedance transformations. The radiating component and the conductive strip feed-line forming the balun may be formed on different layers of a multi-layer circuit structure.
