An antenna for a convenient and economical installation in a small volume within a computer or other electronic equipment. The microstrip antenna includes a ground plane, a radiating patch, and a dielectric layer separating them. A partially short-circuited edge has a plurality of short-circuited sections formed thereon. A microstrip feed line is formed on the partially short-circuited edge, positioned between a first short-circuited section and a second short-circuited section. Preferably, a rectangular ring is formed in the radiating patch, offset so that it is closer to the partially short-circuited edge than to the radiating edge opposite thereto. The microstrip feed line provides an economical connection to a circuit board, and allows positioning the antenna so that the ground plane faces adjacent metal surfaces or circuits. |
