Dc short circuited antenna
WebMay 12, 2007 · The Grounding...or more precisely Short Circuit at DC will indicate usually a 5/8 wavelength antenna. Open circuit usually indicates a 1/4 wave antenna. Its all about impedance matching. A 1/4 wave antenna will present around about 50 or 60 ohms at resonanace so is a reasonable match but the drawback is that the radiation pattern, is … WebThe reflection from a short-circuited line can be described in similar terms to that from an open-circuited line. Just as in the open circuit case where the current must be zero at the end of the line, in the short circuit case the voltage must be zero since there can be no volts across a short circuit.
