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： A transmitting unit of a portable telephone apparatus transmits radio signals by using at least two antennas and simultaneously energizing those antennas with a predetermined amplitude ratio and a predetermined phase difference so that the direction of the main beam of a radiation pattern has a direction substantially opposite to that of the audio radiating direction from a speaker, and so that the mean effective gain is larger than that of when a single antenna is energized. The above energization of at least two antennas is formed only for transmission of telephone speech. A receiving unit of the portable telephone apparatus receives radio signals by using at least two antennas, and selectively receives, by the diversity receiving system, the radio signal having the highest level of those radio signals received by those antennas.
