Daniel W. S. Tam Inventions, Patents and Patent Applications - Justia . . . Abstract: Methods and systems for determining insertion loss for a mast clamp current probe (MCCP) coupled to a monopole antenna are disclosed An exemplary method includes determining a first power radiated by the monopole antenna across a first range of frequencies while driving the monopole antenna using a base-feed arrangement to produce a
A transmit mast-clamp current probe for shipboard HF communications Abstract: The mast-clamp current probe (MCCP) concept uses the ship superstructure as an antenna and couples the signal from the superstructure to the communications system This concept has been successfully implemented for the high frequency (HF) receive side of the communication system

Abstract: Methods and systems for determining insertion loss for a mast clamp current probe (MCCP) coupled to a monopole antenna are disclosed An exemplary method includes determining a first power radiated by the monopole antenna across a first range of frequencies while driving the monopole antenna using a base-feed arrangement to produce a
Electrically small plate antenna that operates at HF The mast-clamp current probe (MCCP) antenna is a ferrite-core current probe device which is designed to couple to existing ship structures, especially the mast, to form an antenna to receive radio frequencies (RF) in the HF (2-30 MHz) frequency range
Correlation between transfer impedance and insertion loss of current probes Abstract: Transfer impedance and insertion loss are two important performance parameters of current probes In this paper the relationship between them is discussed and analyzed First the analysis is carried out from the aspect of their definitions
Bulk Current Injection Probe Test Procedure - EMC FastPass Injection Current Probes are used to inductively couple large RF currents into conductors passing through their aperture The conductors are signal, control and power circuits of equipment under test for conducted susceptibility or immunity
Using the RF Current Probe - Com-Power Current probes are invaluable for measuring high‐frequency common‐mode (CM) currents flowing on wires or cables Experience has proven that poorly terminated (bonded or filtered) cable shields are the number one cause for radiated emissions failures during EMC compliance testing
Bulk Current Injection Testing - A. H. Systems An injection current probe is characterized by its insertion loss (dB) The insertion loss describes the inefficiency of the clamp relative to direct injection into a 50ohm circuit See Figures 1
