In the present discussion covering the most important types, those aspects which are of particular practical interest to the designer will be covered, emphasising available options and including references to the latest advances in feed design. For the sake of descriptive economy and consistency, it will be assumed, unless otherwise stated, that the ...

Microstrip antennas are inherently narrowband. The typical bandwidth of a microstrip antenna is around 4% to 7%. A considerable number of experimental approaches have been undertaken to develop microstrip antennas that have a broader impedance bandwidth than a single microstrip element achieves without external matching.
