摘要： A small-sized wireless device has a whip antenna and a receiver for receiving a call. The whip antenna is provided at the upper side of the rear face of the small-sized wireless device body to improve the antenna performance in a state where a person holds the body to communicate. A rib is provided at a portion of the rear face of the small-sized wireless device body in order to prevent the degradation of the antenna characteristics of the whip antenna at the time of placing the small-sized wireless device body on a metal plate and the like. According to such an arrangement, good sensitivity of the whip antenna can be obtained even when the small-sized wireless device body is placed on a metal plate.

摘要： An antenna matching apparatus capable of eliminating impedance mismatching produced when the antenna element is placed close to the human body in a short time and reducing power loss due to impedance mismatching. This apparatus connects variable capacitance capacitors VC1 and VC2 for impedance adjustment to transmission antenna element TA1, connects variable capacitance capacitors VC3 and VC4 to reception antenna element RA1 respectively, provides beforehand capacitance values of respective variable capacitance capacitors which are impedance matched in a table in a one-to-one correspondence with the distances between the antenna elements and human body and stores the table in storage section (106). The apparatus completes adaptive control processing for any one of transmission antenna element TA1 and reception antenna element RA1, reads other capacitance values corresponding to the capacitance value at that moment from the table and performs adaptive control processing on other antenna elements using the read values as initial values.

摘要： In the adaptive control apparatus, a computation unit computes weighting coefficients, using a first adaptive control method in a proportion α of a first computation amount, where the first adaptive control method has a first convergence rate and a first convergence error. Further, a computation unit computes weighting coefficients from initial values of the weighting coefficients computed by the computation unit, using a second adaptive control method in a proportion (1−α) of a second computation amount, where the second adaptive control method has a second convergence rate slower than the first convergence rate and a second convergence error smaller than the first convergence error. A controller controls determination of a ratio α/(1-α) based on a moving speed of a mobile unit, and controls the computation units to perform computing processes.
