PURPOSE:To enable to realize the low side lobe characteristics, by reducing the amount of stray coupling, through the fit of shield wall having choke construction between slot elements. CONSTITUTION:The shield wall 6 is provided between slot elements 2, and at least one or more groove 7 are given to the wall 6 and the depth is determined to obtain the operation of choke. With this constitution, the surface current due to stray coupling can be cancelled with the choke operation by the grooves 7. |
