    摘要： The connection circuit 108 reduces degradation in the coupling between the antenna elements by performing adjustment to cancel the mutual coupling between the first antenna element 106 and the second antenna element 107 in a first frequency band. Concurrently, the length 110 of the short side of the first antenna element and the length 109 of the short side of the second antenna element are set to predetermined lengths which are different, thereby reducing the amounts of current which does not contribute to radiation. With such a configuration, it is possible to achieve high-efficiency loosely coupled MIMO array antennas operating in the same frequency in a portable wireless terminal.

    摘要： A controller of a MIMO antenna apparatus calculates a current transmission capacity based on signal levels detected by a signal level detector circuit. The controller calculates an estimated transmission capacity assuming that at least one of antenna elements currently connected to a MIMO modulator and demodulator circuit is changed to a further antenna element not connected to the MIMO modulator and demodulator circuit, based on the detected signal levels and degrees of electromagnetic coupling stored in a degree-of-coupling memory. The controller controls a switch circuit to connect the further antenna element to the MIMO modulator and demodulator circuit when the current transmission capacity becomes lower than the estimated transmission capacity.

    摘要： There is provided a flip portable radio that can be reduced in thickness and size; that requires a broadband characteristic for an antenna; and that can exhibit high communication performance according to various states of usage.A flip portable radio has a matching circuit that feeds power to a metal rotary shaft 14 which makes an upper enclosure 12 and a lower enclosure 11turnable and which matches impedance to 50 ohms at two operation frequencies or more. A diameter L1 of a cross section of a metal rotary shaft 14 is set to about 1/20 or more of a wavelength λ2. An effective length of a metal rotary shaft 14 is set to about λc/4 of a wavelength λc of a center frequency of a high frequency band. The metal rotary shaft 14 is placed at a given interval away from a first circuit board 11A and a second circuit board 12A.
