Triangular wave-shaped direction-selectable signal detection sampler

The utility model discloses a triangular wave-shaped direction-selectable signal detection sampler, which belongs to the technical field of radio and microwave, and comprises a main line, an auxiliary line and a microwave dielectric plate, according to the utility model, through the interspersed design of the zigzag structures between the main line and the auxiliary line, the plurality of capacitors are bridged between the main line and the auxiliary line from the angle of an equivalent circuit, the potentials at the two ends of each capacitor are the same in an even-mode transmission state, no current passes through the capacitors, no influence is caused on transmission signals, and it can be seen that no current passes through the capacitors. Under the condition of odd mode transmission, signals at the two ends of each capacitor are equal in size and opposite in phase, each capacitor can be equivalent to series connection of two same capacitors, meanwhile, a series connection common connection point of the
