Abstract (in Japanese) (See Japanese page) 
(in English) When the waveguide edge-shunt slot array is arrayed in the direction of waveguide width, compact slot which can be settled on the narrow wall of the waveguide is necessary. Crank shaped slot is a well known compact slot that can be settled on the narrow wall of the waveguide with its length be resonant. However, It cannot achieve sufficient small conductance. Because of this, it is difficult to match the slot to waveguide without matching circuit. In this paper, Z shaped slot partially overlapping the waveguides wall thickness is proposed. It can achieve sufficient small conductance and small cross polarization. As an example, 6-element array using the Z shaped slot is provided. As a result, the band width, which is defined by the reflection coefficient less than -10 dB, of proposed Z shaped slot have achieved 4 times wider than conventional slot. In addition, the cross polarization can be reduced by -8.9 dB.
