Abstract
A microstrip antenna structure ( ) for used in broadband, multi-frequency range applications includes a dipole antenna ( ) comprising two dipole elements ( ), a dielectric substrate ( ) on which the dipole elements are symmetrically disposed, and a feeding system ( ) connected with the dipole antenna. Each dipole element comprises a triangular patch ( or ) and a V-shaped tentacle patch ( or ) extending from the triangular patch. The two dipole elements together form a butterfly structure antenna. This butterfly structure allows the dipole antenna to operate efficiently in a broadband range in the 2.4-2.5 GHz, 5.15-5.35 GHz and 5.45-5.75 GHz frequency bands.
