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 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.

Abstract: Folded dipole antenna elements (2, 4) are disposed generally in parallel, being spaced by a distance smaller than a half of the wavelength employed. The antenna elements (2, 4) are connected to a combiner (16) via feeders (12, 14) having different lengths. The difference in length between the feeders (12, 14) is such that received signals resulting from a radio wave coming to the antenna elements (2, 4) from the front and received by the antenna elements (12, 14) are in phase with each other at the inputs (16a, 16b) of the combiner (16), whereas received signals resulting from a radio wave coming to the antenna elements (2, 4) from the back and received by the antenna elements (12, 14) are 180° out of phase with each other at the inputs (16a, 16b) of the combiner (16).

Two extension elements (24a, 26a) extend outward from respective ones of opposed outer ends of the dipole antenna (4a). The length of the dipole antenna (4a) is determined to make the multiple frequency band antenna capable of receiving radio waves in the UHF band, and the sum of the lengths of the dipole antenna (4a) and the extension elements (24a, 26a) is determined to make the multiple frequency band antenna capable of receiving radio waves in the VHF band. PIN diodes (28a, 34a) are connected between the respective extension elements (24a, 26a) and the respective outer ends of the dipole antenna (4a).

An antenna device (2b) includes third and fourth dipole antennas (4a, 6a) spaced from each other by the distance and is disposed orthogonal to the antenna device (2a). A first phase adjusting circuit (104a) combines signals from the first and second antennas (4a, 6a) after adjusting their phases, in such a manner that the resultant combined signal selectively assumes a forward directivity state exhibiting a forward directivity and a backward directivity state exhibiting a backward directivity. Similarly, a second phase adjusting circuit (104b) combines signals from the third and fourth antennas (4b, 6b) after adjusting their phases, in such a manner that the resultant combined signal selectively assumes a rightward directivity state exhibiting a rightward directivity and a leftward directivity state exhibiting a leftward directivity.
