Abstract: With a power supply provided for a smart antenna, whether the antenna is connected is determined according to whether the power supply is connected. When it is determined that the smart antenna is not connected, power supply to units related only to controlling of the smart antenna is stopped, whereby power saving is realized. Further, user's setting for discriminating kinds of antennas becomes unnecessary and, when a smart antenna is not connected, power supply for the same can be prevented.

Abstract: The antenna apparatus includes first to fourth antenna elements successively arranged at regular angular intervals around the central point on the same plane and respectively having first to fourth feed points, and a phase shifter delaying the phase of the received electric wave approximately by 90 degrees. The unidirectivity of the antenna apparatus is controlled in four directions of 0 degree, 90 degrees, 180 degrees and 270 degrees by selectively connecting the first to fourth feed points, the phase shifter and a television receiver. Therefore, multipath interference in these directions can be suppressed.

Abstract: A variable directivity antenna (2) has directivity direction angularly variable stepwise about itself. A tuner (8) selects a desired one from high frequency signals received at the antenna (2). The tuner (8) detects the level of the received signal and supplies it to a control unit (10). The control unit (10) searches for received signal levels, equal to or higher than a threshold level, of the received signal received in plural states in which the directivity of the antenna (2) is placed in different ones of directivity directions, and detects a slope of the received signal levels within a frequency range of the received signal. The control unit (10) employs the searched directivity direction for the smallest one of the detected slopes as the direction to which the antenna (2) is directed to receive the signal.

Abstract: A variable directivity antenna (2) has directivity direction variable stepwise along the circumference of a circle centered about it. A tuner (8) selects a desired one from high frequency signals received at the antenna (2). The tuner (8) detects the level of the received signal and supplies it to a control unit (10). The control unit (10) searches for reception signal levels, equal to or higher than a threshold level, of the received signal received in antenna states in which the directivity of the antenna (2) is placed in different ones of directivity directions, and detects a signal-to-noise ratio of the signal received from directions adjacent to each of the searched directivity directions corresponding to the searched signal levels. The control unit (10) employs the searched directivity direction for the highest signal-to-noise ratio as the direction to which the antenna (2) is directed to receive the signal.

Abstract: A radiator includes two dipole elements as plate-shaped conductors. The radiator further includes two conductive line portions provided on opposite sides of a prescribed axis, sandwiching both of the two dipole elements, each having one end connected to one dipole element and the other end connected to the other dipole element. The two conductive line portions are formed to conform to the shapes of the dipole elements. As the conductive line portions having such shapes are connected to the dipole elements, better characteristics can be attained over wide frequency range and the size can be made smaller than the conventional radiator. Thus, an antenna having smaller size and improved characteristics can be provided.
