ABSTRACT:
A multi-band antenna for enabling an electronic device (such as a laptop computer) to operate in two frequency bands comprises an insulative substrate (30), a conductive element disposed on the substrate, and a feeder cable (40). The conductive element and the feeder cable form a planar inverted-F antenna (10, 23, 21, 25, 24, 11) operating in a lower frequency band and a planar loop antenna (10, 23, 22, 24, 11) operating in a higher frequency band.
