Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).

QSN1 Which antenna type would be best for a project requiring a specific frequency? ANS1 Resonant antennas QSN2 How could an antenna be made to coordinate with the needed frequency? ANS2 built or ordered QSN3 What factor would result in a desired feedback independence? ANS3 particular antenna design QSN4 If you were unable to choose the antenna you wanted how could you still achieve this result? ANS4 matching network
