Abstract The present invention relates to structure desing of FR trapper. The FR trapper consists of three parts including main transmission line, resonant cavity and coupling mechanism to connect the above said two parts. The main transmission line consists of an inner strip conductor and an outer conductor; the resonant cavity consists of a cylindrical or spiral inner conductor with deep hole, an outer conductor and an adjustable screw; and the coupling mechanism consists of a main transmission line coupling sheet, a resonant cavity coupling sheet and a connecting metal rod in between, or a main transmission line coupling sheet and a metal rod connecting the coupling sheet and spiral inner conductor. The present invention is small, simple, stable and low in cost and is especially suitable for high-power TV emission system.
