摘要： The present invention relates to an antenna mainly used in a cellular phone or the like and to a communication terminal using it. It is hence an object thereof to realize an antenna having a high radiation efficiency, a wide adjustable range of the impedance of the antenna, and a capability of matching with an RF circuit by the structure itself without using a matching circuit. The number of structural parameters for adjusting the impedance of the antenna increases. To achieve the object, the antenna in the communication terminal of the present invention has a radiation element wound spirally around an insulating core in the winding direction inverted at an arbitrary position. The antenna is hence capable of adjusting the impedance, and as a result, the number of structural parameters of the antenna increases, and the adjustable range of the impedance of the antenna is expanded.
