The at least one controllable resonating capacitor determines a resonance frequency of the antenna device. An object of the invention is to provide a compact antenna device which can obtain a desired matching characteristic without using a separate matching circuit which limits miniaturization of the antenna system as a whole and forms a factor of limiting the efficiency of the antenna and raising cost when the antenna is incorporated into the terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Compact antenna device","description":"The present invention relates to an antenna device including an integrated matching circuit being implemented by at least one controllable capacitor for a number of frequencies.
