Abstract (en)
[origin: WO9424723A1] A small microstrip antenna (200) useful in portable electronic devices including pagers, telephones, and portable computers. The microstrip antenna (200) includes a ground plane layer (212), a dielectric layer (214), and a radiating patch (216) with a rectangular ring (250) formed therein. The radiating patch (216) is short circuited to the ground plane layer (212) along a shorted edge (222). The ring (250) may be positioned offset so that it is closer to the short circuited edge (222) than to the radiating edge (220). The antenna can fit within a standard PCMCIA slot in portable computers. The small size of the antenna allows orientation within a housing to optimize the radiation from the antenna. The antenna is useful in stand alone computers.
