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).

摘要： Disclosed is a portable wireless device which can receive signals at a wideband with good sensitivity, and change a narrowband wherein signals are received with high sensitivity. In this device, a wireless unit (105) demodulates signals received by an antenna (101) or modulates signals to be transmitted by the antenna (101). Matching circuits (103-1 to 103-n) are connected between the antenna (101) and the wireless unit (105) and match impedance so that the impedance of the antenna (101) and the impedance of the wireless unit (105) have a complex conjugate relation. A plurality of these are respectively provided for a plurality of different frequency bands where matching is performed.

摘要： Disclosed is a portable wireless terminal wherein deterioration in antenna performance when placed on a metal desk or other structure can be prevented without sacrificing designability and without increasing the number of components. In this terminal, a hinge part (103) functions as an antenna which resonates at a frequency of a first wireless system (150). A whip antenna (112) faces the surface of a first circuit board (104) that is opposite the surface faced by an input device (115), is disposed substantially parallel to the first circuit board (104), and resonates at a frequency of a second wireless system (160). A second contact spring (110) electrically connects a second wireless circuit (108) to the antenna element of a whip antenna (112) and is disposed perpendicularly to the first circuit board (104). A switch (113) grounds the whip antenna (112) and second contact spring (110) to the first circuit board (104) when the second wireless system (160) is not operating.

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 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.
