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.

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.

摘要： An array antenna apparatus includes a first feeding element having a first feed point, a second feeding element having a second feed point, and a first parasitic element electrically connected to the respective first and second feeding elements. In a first frequency band, respective resonances in the feeding elements occur independent of each other, by eliminating electromagnetic mutual coupling between the feeding elements, and exciting the first feeding element through the first feed point as well as exciting the second feeding element through the second feed point. In a second frequency band lower than the first frequency band, a loop antenna having a certain electrical length is formed by the first and second feeding elements and the first parasitic element, and a resonance of the loop antenna substantially occurs by exciting the first feeding element through the first feed point.
