Similarities
Both antennas and waveguides belong to electromagnetic components.
Antennas and waveguides transmit/received signal by required power and frequency.
Differences
Antennas transmit signals is wireless in a medium normally, however waveguides transmit wireless signals by metal like aluminum, brass and copper.
Antennas can cover various frequency range which is from low and high, but waveguides range is not very broad.
The antenna efficiency can be specified, but wavegiudes gain is defined by the operation mode.
The antenna efficiency and bandwidth are fixed over the specific frequency range, but it also depends on the mode of waveguide.
Antennas are suitable for long distances signal transmission but waveguides are not.
