摘要： A miniaturized power distributing device with harmonic suppression function and low cost is set in a substrate, and includes first, second, and third metal levels. The first metal level includes a power divider to divide one signal into multiple output signals, or to combine multiple input signals into one output signal. The second metal level includes a filter structure to filter out harmonics. The third metal level is isolated against electromagnetic wave signal leaking from the second metal level. The second metal level is set between the first and third metal levels, dielectric layers are set between the first and second metal levels and between the second and third metal levels.

摘要： A double-frequency antenna structure with a high degree of electrical isolation between long distance and short distance antennas includes a dielectric substrate having at least two corners and a center area. A first set of antenna arrays is positioned at the corners. A second set of antenna arrays is positioned at the center area. At least one first folded isolation plate is mounted on the dielectric substrate, and positioned between the first set of antenna arrays and the second set of antenna arrays. At least one second folded isolation plate each is mounted on one first folded isolation plate.

摘要： A small-scale branch-line coupler suitable for use in mobile devices includes a first, second, third, and fourth ports, respectively acting as input, transmission, coupled, and isolated ports. A first, second, third, and fourth connection parts are connected to the ports and transmission lines. First angular transmission lines are between first and second ports, third angular transmission lines are between third and fourth ports. A third long strip transmission line connects the first port and the fourth port. A fourth long strip transmission line connects the second port and the third port. The branch-line coupler occupies a small area and has high performance.

摘要： A power dividing circuit includes a first transmission sub-circuit having an input port and a first resonant circuit, a second transmission sub-circuit having a second resonant circuit, and a third transmission sub-circuit having a third resonant circuit. A matching element is coupled between the second transmission sub-circuit and the third transmission sub-circuit. An input carrier signal is divided into a first signal to the second transmission sub-circuit and a second signal to the third transmission sub-circuit through the first transmission sub-circuit. The second resonant circuit and the third resonant circuit generate resonant frequency to reduce high frequency harmonics under a specific frequency range in the input carrier signal. A power divider is also provided.
