ABSTRACT:
A meander inductor is disclosed, the inductor is disposed on a substrate or embedded therein. The meander inductor includes a conductive layer composed of a plurality of sinusoidal coils with different amplitudes and in series connection to each other, wherein the sinusoidal coils with different amplitudes are laid out according to a periphery outline. The profile of the meander inductor is designed according to an outer frame range available for accommodating the meander inductor and is formed by coils with different amplitudes. Therefore, under a same area condition, the present invention enables the Q factor and the resonant frequency fr of the novel inductor to be advanced, and further expands the applicable range of the inductor.
