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： There is provide a mobile radio apparatus capable of suppressing a mismatching loss, and increasing a transmission/reception sensitivity by means of instantly and adaptively matching the impedance between the antenna and the transmission/reception circuit whatever situation a mobile radio apparatus, such as a mobile phone or the like, may be. In a mobile radio apparatus (1), when starting control of the matching circuit (102), a control section (105) evaluates an initial chromosome stored in a storage section (106), and if there is an initial chromosome for providing an impedance matching, controls the matching circuit (102) so as to have a load value corresponding to this initial chromosome. If there is no initial chromosome for providing the impedance matching, the control section (105) evolves the initial chromosome with a genetic algorithm, derives a chromosome for providing the impedance matching, and controls the matching circuit (102) so as to have a load value corresponding to the derived chromosome.

摘要： A top conductor 11, a ground conductor 12, and side conductors 13 form an antenna box having two openings 22 and 23. Antenna elements 14 and 15 are placed inside of the antenna box, and are connected to power supply points 16 and 17, respectively. A power supply control circuit 20 has a switching function of connecting either one of the power supply points 16 and 17, to an external connecting terminal 21. Depending on the antenna element 14 or 15 being operated, the antenna has a directivity biased to a desired direction. The power supply control circuit 20 may have a signal combining/separating function, a phase shifter 26, or an amplitude adjusting circuit 27. With this, it is possible to provide a small, slim antenna capable of biasing the directivity to a desired direction and controlling the directivity even after installation.

摘要： Four antenna units arranged adjacent to each other are respectively connected to switches, and are connected to load impedance elements via the switches, or connected to an output terminal and a comparator via a switch. Another ends of the load impedance elements are grounded. The comparator judges which antenna unit receives a radio signal having the maximum signal level among the antenna units. A controller controls the switches and the switch so that the antenna unit that receives the radio communication signal having the maximum signal level is connected to the output terminal and the other antenna units are connected to the load impedance elements.
