摘要： The unbalanced feeding antenna element 201 is fed power from one end and placed on the upper surface of the circuit substrate 103. The passive element 202 has open both ends, is set to a length corresponding to a predetermined frequency, placed in substantially parallel to the unbalanced feeding element 201 placed on the circuit substrate 103 at a distance of approximately 1/10 or less of a wavelength at a frequency used for transmission/reception. This suppresses the antenna current flowing into the circuit substrate 103 to a minimum level and makes radiation from the passive element 202 dominant compared to radiation from the circuit substrate 103. This makes it possible to suppress a reduction in the antenna gain caused by the human body when the user uses the communication terminal apparatus.
