Broadband lightning protection device for high frequency lines has waveguide divided into two sections with reduced characteristic impedance compared to connected HF line by stub line

摘要

The device (1) has a waveguide (5) and a stub conductor (8) branching off from the waveguide and connected to earth potential at the end remote from the branching point (9). The waveguide is thereby divided into two sections with reduced characteristic impedance compared to the connected HF line and the characteristic impedance of the stub line is increased relative to that of the HF line.
