A multi-band antenna for mobile handsets

Conventional microstrip antennas in general have a conducting patch printed on a grounded microwave substrate, and have the attractive features of low profile, light weight, easy fabrication, and conformability to mounting hosts. Microstrip antennas however have a narrow bandwidth, and bandwidth enh...
