<P>PROBLEM TO BE SOLVED: To provide a microwave antenna where spurious radiation and crosstalk or coupling do not occur. <P>SOLUTION: A radiator array 40 having a plurality of columns 42 of radiator patches 43 is arranged on an upper face of a substrate 22. An input feed line and a power distribution network are disposed on a bottom face of the substrate 22. The power distribution network includes a plurality of ends, each of which is adapted to electrically connect to an end 50 of the related column 42 of the radiator array 40 through a veer so formed as to penetrate the substrate 22. A conductive layer 64 is installed on a part of the upper face of the substrate 22. Thereby, the conductive layer 64 covers the power distribution network and shields the power distribution network from the radiator array 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
