COMPACT PLANAR INVERTED F-ANTENNA FOR MULTIBAND COMMUNICATION

摘要

A multi-band antenna for sending/receiving wireless communication signals in a plurality of frequency bands. The multi-band antenna has a feed element for sending/receiving signals associated with the wireless communication signals. A stepped-impedance structure is connected to the feed element. The stepped-impedance structure has a plurality of concatenated stepped-impedance elements with each stepped-impedance element having a predetermined impedance and a predetermined electrical length associated with a resonance mode for sending/receiving wireless communication signals in a respective frequency band of the plurality of frequency bands.
