|Image of the End-loaded dipole antenna.|
The end-loaded dipole is an electrically short antenna having a total length < λ/4. It's performance is comparable with a normal dipole having an increased impedance bandwidth. Although electrically small antennas usually have high Q's and therefore narrow impedance bandwidths (1/Q) end or top-loading lowers the Q and thus increases the bandwidth. End-loaded dipole antennas are popular for long range communication in LF, VLF and VHF bands.
