摘要： A traveling-wave combining array antenna apparatus includes first and second traveling-wave array antennas. The first traveling-wave array antenna has a plurality of antenna elements provided at intervals along a first feeder line, and has a radiating directivity characteristic. The second traveling-wave array antenna has a plurality of antenna elements provided at intervals along a second feeder line, and has a main beam of a half-value width and a radiating directivity characteristic of a side lobe level lower than that of the first traveling-wave array antenna. A transmitting signal is split into two signals, feeding the signals to the first and second traveling-wave array antennas, which are provided so that a variation of main-beam radiating angle of electromagnetic wave of transmitting signal radiated from the first traveling-wave array antenna corresponding to a frequency change, and that of the second traveling-wave array antenna are substantially canceled by each other.

摘要： An antenna device comprising a plurality of directional antennas which are aligned on the same axis in one direction and which are also arranged in a manner that the main radiation directions of the plurality of directional antennas deviate from each other in a direction orthogonal to the direction. Hence, a drop in directivity due to the array factor can be prevented and radiation characteristics in the plane orthogonal to the direction is expanded.
