- Abstract
- In this letter, experimental results are shown for an E-field probe using variable chip resistor values to improve performance. The E-field probe consists of three small orthogonal dipoles with a diode and a lossy transmission line. Since the transmission line does not receive transmitted signals directly or indirectly, a high impedance value of the transmission line is required. To achieve such a high impedance value, chip resistors are inserted in the transmission line. In this letter, variable resistors are used in the transmission line to improve probe performance of such areas as sensitivity and isotropy. Finally, probes with identical and variable resistance values are fabricated, performance levels are measured, and characteristics are compared.
