Abstract

The invention relates to an air variable capacitor including a mobile comb and a fixed comb. Each of the combs include a body and teeth each having an end fixed to the body and free end. The teeth of the mobile and fixed combs being interdigital and an the air-gap of the capacitor is adjustable by the transverse movement of the teeth of the mobile comb. The teeth of the mobile comb have geometric differences between one another, in order to attenuate the transverse resonance modes of the mobile comb.
