DefinitionA <LOG PERIODIC ANTENNA> is an <ANTENNA> that is a wideband antenna used in the HF, VHF and UHF bands, made up of a number of dipoles mounted along a straight line
Each dipole is 180 deg. out of phase with the preceding element. The length of the dipoles will vary gradually over the antenna, depending on the frequency band to be covered. In the HF band, wire structures may be used, while antennas for the UHF band may be made in the form of printed circuit boards protected by a glassfibre radome.
