摘要： An adaptive antenna apparatus includes antenna elements. One of the antenna elements has an electrical length L1 larger than λ/2, and equal to or smaller than a predetermined upper-limit wavelength, where λ is a wavelength of a radio signal. Another antenna element has an electrical length L2 equal to or larger than a predetermined lower-limit wavelength and equal to or smaller than λ/2. A controller adaptive-controls the adaptive antenna apparatus to form a radiation pattern of the adaptive antenna apparatus including a plurality of nulls substantively in a direction of an interference wave by adjusting at least one of an amplitude and a phase of each radio signal received by the first and second antenna elements.

摘要： In a helical antenna apparatus, a first variable capacitance element is connected between a first helical antenna element and a second helical antenna element, and a second variable capacitance element is connected between a first terminal of a balanced port of a balanced to unbalanced transformer and the first helical antenna element. A third variable capacitance element is connected between a second terminal of the balanced port of the balanced to unbalanced transformer and the second helical antenna element. A detector measures a detection voltage Vd corresponding to a reflected power of a reflected signal reflected from the first and second helical antenna elements when the first and second helical antenna elements are fed with a transmission signal from a radio transmitter, and an adaptive controller adaptively controls respective capacitance values of the first to third variable capacitance elements.

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.

摘要： An adaptive antenna apparatus including a reception adaptive control circuit is provided. The reception adaptive control circuit adaptively controls respective received signals received by a plurality of antenna elements, and outputs the adaptively-controlled received signals as a combined received signal. A demodulator demodulates the combined received signal to a demodulated signal, and demodulates the respective received signals separately received by the respective antenna elements to demodulated signals. A controller compares signal quality of the demodulated signal of the combined received signal with signal qualities of the demodulated signals of the respective received signals separately received by the respective antenna elements, respectively, selects a demodulated signal having the highest signal quality, and controls to receive a received signal including a selected demodulated signal.

摘要： An adaptive antenna apparatus includes two antenna elements and a parasitic element to which a variable reactance element is connected, and selects an adaptive control processing according to detected signal quality. A controller executes a first adaptive control processing for adaptively controlling respective received signals received by the respective antenna elements and outputting the respective received signals after the adaptive control as a combined received signal, and executes a second adaptive control processing for reactance controlling an element value of the variable reactance element. The controller executes the first adaptive control processing. The controller executes a communication processing when the detected signal quality is equal to or larger than a predetermined threshold. The controller executes the second adaptive control processing when the detected signal quality is not equal to or larger than the threshold.

摘要： A small-sized mobile radio has a built-in antenna is high enough to enhance the antenna characteristics. In the mobile radio, a base plate is structured by a section (antenna-housing section) including a supply portion and a short-circuiting portion, for example, of an antenna element which affect the antenna characteristics, and a section (circuit-housing section) which is the rest of the base plate. The antenna-housing section is so positioned so as to keep the built-in antenna high enough, that is, to keep the space between the base plate and the antenna element large enough. On the other hand, the circuit-housing section is positioned toward the back of the cabinet to provide room for a display and a key section.
