摘要： In an apparatus for measuring a specific absorption rate (SAR) for use in a radio apparatus, a first near magnetic field of a radio wave radiated from a reference radio apparatus is measured in free space, and an SAR of the radio wave radiated from the reference radio apparatus by using a predetermined phantom according to a predetermined measurement method. A transformation factor α is calculated by dividing the measured SAR by a square value of the measured first near magnetic field, and a second near magnetic field of a radio wave radiated from a radio apparatus to be measured is measured in free space. Then an SAR of the radio wave radiated from the radio apparatus to be measured is estimated and calculated by multiplying a square value of the measured second near magnetic field by the calculated transformation factor α.

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： A mobile wireless apparatus wherein matching circuits can be independently designed, while the increase in the circuit scale can be suppressed and the cost can be reduced. In this apparatus, a filter (102) suppresses a frequency band (f2-f3) of signals received by an antenna element (101). A filter (105) suppresses a frequency band (f1) of the signals received by the antenna element (101). A wireless unit (104) acquires data that is obtained by demodulating the signals obtained by suppressing the frequency band (f2-f3) and superimposing the demodulated signals on the signals of the frequency band (f1). A wireless unit (107) acquires data that is obtained by demodulating the signals obtained by suppressing the frequency band (f1) and superimposing the demodulated signals on the signals of the frequency band (f2-f3). A matching circuit (103), which is connected between the filter (102) and the wireless unit (104), matches the impedances of the filter (102) and wireless unit (104). A matching circuit (106), which is connected between the filter (105) and the wireless unit (107), matches the impedances of the filter (105) and wireless unit (107).
