Multiband Antenna and Multiband Antenna Configuration Method

摘要

A multiband antenna configuration method for configuring a multiband antenna to transmit and receive radio signals of a plurality of frequency bands includes determining a distance between a magnetic conductor reflector and a first radiation portion, calculating a first and second reflection phase value at the first and second center frequency of a first and second frequency band according to a configuration requirement corresponding to the distance, determining a length and width of the multiband antenna, adjusting materials and geometric features of the magnetic conductor reflector to change a curve representing relationship between reflection phases of the magnetic conductor reflector and frequencies and to make the first reflection phase corresponding to the first center frequency and the second reflection phase corresponding to the second center frequency equal to a first reflection phase value and second reflection phase value, and determining the materials and geometric features according to the curve.
