ことを特徴とするスロツトアレイ空中線。 In slot array antennas used as broadside arrays with linear array and planar array configurations, this antenna is divided into equal areas and 2N (N is an integer) small antennas are used to eliminate reflections over a wide range of frequencies. 2N -1 pairs of small antennas separated by a distance of 1/4 wavelength for each of the N frequencies in the band, and between the small antennas and the small antennas are installed at different positions in the direction of radio wave radiation. A slot array antenna characterized in that a radio wave absorber is attached to the side wall of the small antenna formed in the slot array antenna.
