Abstract :
A dual band 802.11a/b antenna system fabricated on two separate artificial magnetic conductor (AMC) substrates is described. This low profile antenna, which is 3.4 mm in thickness and 12 mm in width, is mounted onto the metal housing above a laptop screen. In each band, the antenna system has a peak gain at the horizon of at least 2 dBi and has -5 dBi or greater gain over 80% of the horizon azimuth angles.
