According to the circuit theory, the electrode structure of the probe is designed. The unpackaged size of the fabricated probe is as small as 60× 6 × 0.5 （mm）. The measured results show that the half wavelength voltage is 7.7 V, the ±5 dB baseband range is 3 GHz, and the minimum detectable field is lower than 90 dB.μV/m （bandwidth 100 Hz）. Therefore it can be used in the electromagnetic compatibility （EMC） measurements. OCIS codes： 130.3120, 130.6010, 230.4110.展开更多
