(57) Abstract Microstrip distribution network for suppressing the mode whose on distribution network side of microstrip distribution network is not desirable and the device for the group antenna. This device evades the coupling whose between of the antenna element (120,220,317,520,620) which especially is jointed to microstrip distribution network is not desirable. The wave guide fundamental structure (100,200,300,400) which it pushes out in principle and forms from aluminum in U letter condition paralleling to two path cords (101,201,301,401), making use of the terminal area (111,211,311,411) of two for the ground plane (116,216,316,416) of the microstrip distribution network which parallels to each path cord electric conductivities at least is joint to microstrip distribution network. At least one part of the ground plane and together, the wave guide fundamental structure forms the wave guide structure. Wave guide structure tries to possess the cutoff frequency which is higher than the highest frequency which is used for microstrip distribution network to a necessary size. Because the wave guide structure functioning it does this, as the high-pass filter, is generated desirable mode is suppressed with the group antenna and with the discontinuity of distribution network.
