摘要： A second slit 117 and a fourth slit 119 provided in a first antenna element 150 and a first slit 116 and a third slit 118 provided in a second antenna element 151 are adjusted such that the mutual coupling between the first antenna element 150 and the second antenna element 151 in the desired frequency band is canceled, and reduces degradation in coupling between antenna elements without connecting the antenna elements through components and the like. With such a configuration, it is possible to achieve high-efficiency loosely coupled MIMO array antennas operating in the same frequency band in a portable wireless terminal.

摘要： A first connection circuit (108) is controlled so as to cancel mutual coupling impedance existing between a first antenna element (106) and a second antenna element (107) at a first frequency band, thereby lessening deterioration of coupling between the antenna elements. A second connection circuit (111) is controlled so as to cancel mutual coupling impedance existing between a first passive element (109) and a second passive element (110) at a second frequency band, thereby lessening deterioration of coupling between the passive elements. By means of the configuration, it is possible to implement a low-coupling antenna that operates at two frequency bands in a wireless mobile terminal.

摘要： A first antenna element is embodied in a blanched structure, and a second antenna element is embodied in a blanched structure. A low coupling circuit for increasing susceptance with an increase in frequency is interposed between the first antenna element and the second antenna element. The first antenna element and the second antenna element exhibit resonance of a Y12 component of an admittance matrix between first and second frequencies and between second and third frequencies. The first branch element and the third branch element assume a value of nearly a quarter of a resonant electrical length of the Y12 component of the admittance matrix between the first and second frequencies. The second branch element and the fourth branch element assume a value of nearly a quarter of the resonant electrical length of the Y12 component of the admittance matrix between the second and third frequencies.

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 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).
