FIELD: control-measuring equipment engineering, possible use for controlling defects in structures made of reinforced concrete. ^ SUBSTANCE: in UHF flaw detector receiving and transmitting antennas are made in form of two pairs of stripe resonators positioned on one substrate, and positioned on one axis. Stripe resonators in each pair via transformers are connected respectively to input and output clamps. The latter are positioned on different sides of axis of stripe resonators. ^ EFFECT: increased sensitivity. ^ 1 dwg |
