摘要: A multi-directional resonant-type electromagnetic wave absorber includes: at least one ground layer; a first dielectric layer and a second dielectric layer respectively formed on different outer surfaces of the ground layer; a first resistive pattern layer formed on an outer surface of the first dielectric layer; and a second resistive pattern layer formed on an outer surface of the second dielectric layer. Herein, the electromagnetic absorption performance is adjusted by changing one or more of thicknesses, permittivities, and permeabilities of the dielectric layers, thicknesses of the resistive pattern layers, and a reflection coefficient of the ground layer.

摘要: An internal antenna for use in a mobile handset is formed of a single conductive plate. The internal antenna includes a first meander-shaped portion having one or more slots, including a first bent portion bent downward at a side edge of the first meander-shaped portion; a second meander-shaped portion having one or more slots, including a second bent portion bent downward at an end of the second meander-shaped portion; and a common portion physically connected to the first and the second meander-shaped portion. The first meander-shaped portion together with the common portion forms a first radiating element and the second meander-shaped portion together with the common portion forms a second radiating element, the first radiating element having a first resonant frequency and the second radiating element having a second resonant frequency.
