Chart of Common Frequency Bands. Basically the frequency bands each range over from the lowest frequency to 10 times the lowest frequency. Antenna engineers further divide the bands into things like "X-band" and "Ku-band". That is the basics of frequency.

Frequency range. Antennas have different frequencies they are tuned for, in addition to the bandwidth or range or frequencies they can cover. Horn antennas and similar designs have a relatively narrow bandwidth while others such as a log periodic in comparison are very wide.
The frequency range or bandwidth over which an antenna functions well can be very wide (as in a log-periodic antenna) or narrow (as in a small loop antenna); outside this range the antenna impedance becomes a poor match to the transmission line and transmitter (or receiver).
The bandwidth of an antenna is the frequency range over which the antenna radiates. The bandwidth can be defined in different ways; this page presents an introduction to antenna bandwidth. Polarization of Waves. All electromagnetic plane waves have an associated polarization.
When selecting an antenna, the range of frequencies that will be transmitted or received as well as their bandwidth should be considered. Some antennas are designed to operate over a narrow range of frequencies while other antennas are designed to operate over a broader band of frequencies.
Frequency range. Antennas have different frequencies they are tuned for, in addition to the bandwidth or range or frequencies they can cover. Horn antennas and similar designs have a relatively narrow bandwidth while others such as a log periodic in comparison are very wide.
The High Frequency (HF) band is most useful in shortwave radio applications, as well as aviation air-to-ground communications. Dipole antennas, such as the Yagi, quad, and log-periodic antennas, operate within the higher frequencies of the HF band.
