摘要： An antenna is provided which can reconcile a low antenna resonance frequency and broadband frequency characteristics, while attaining stable impedance characteristics and enhanced design flexibility. A conductive plate is coupled to a conductive base plate via a first metal lead. A voltage is applied to the conductive plate from a supply point via a second metal lead. A conductive wall is electrically coupled to the conductive plate at one end thereof. An electromagnetic field coupling adjustment plate is electrically coupled to the other end of the conductive wall. The electromagnetic field coupling adjustment plate is disposed so as to leave a predetermined interspace between itself and the conductive base plate, thereby creating a capacitor in conjunction with the conductive base plate. The conductive wall and the electromagnetic field coupling adjustment plate are disposed so as to maximize a path length from a shot-circuiting portion (at which the conductive plate is coupled to the first metal lead) to an open end of the electromagnetic field coupling adjustment plate. Preferably, a current path extending from a supply portion (at which the conductive plate is coupled to the second metal lead) to the short-circuiting portion has a length equal to a ½ wavelength for a desired resonance frequency.

One end of a linear conductor 21 is connected perpendicularly to the center of the disk-shaped conductor 22, and the outer edge of the disk-shaped conductor 22 is connected to the inner edge of the ring-shaped conductor 24 via an anti-resonance circuit 23. Moreover, the outer edge of the ring-shaped conductor 24 is connected to the inner edge of the ring-shaped conductor 26 via an anti-resonance circuit 25. Due to the anti-resonance circuits 23 and 25, electrical blocking can be attained, so that an electromagnetic wave of a first frequency f1 is excited by the system extending from the linear conductor 21 to the disk-shaped conductor 22, an electromagnetic wave of a second frequency f2 is excited by the system extending from the linear conductor 21 to the ring-shaped conductor 24, and an electromagnetic wave of a third frequency f3 is excited by the system extending from the linear conductor 21 to the ring-shaped conductor 26. Thus, a small monopole antenna can be attained that has a simple structure and can be operated at a plurality of frequencies.

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.
