Abstract
Disclosed is a small, lightweight antenna having a relatively high gain, particularly suited for use with a portable radio device such as a bidirectional pager. In an exemplary embodiment, the antenna includes a loaded monopole radiator and a ground radiator. The loaded monopole radiator includes first and second conductors on a printed circuit substrate, where the first conductor has a given length oriented in a horizontal direction. The second conductor has a meander line shape and is oriented in a vertical direction. The ground radiator includes separately a first ground and a second ground at a lower portion of the printed circuit substrate, where the first and second grounds are symmetrical with respect to the second conductor.

A small antenna for a portable radio device, comprising:
- a loaded monopole radiator including a first conductor on a printed circuit substrate, said first conductor having a given length oriented in a horizontal direction, and a second conductor having a meander line shape and oriented in a vertical direction;
- and
- a ground radiator including separately a first ground and a second ground at a lower portion of said printed circuit substrate, said first and second grounds being symmetrical with respect to said second conductor.
An antenna, comprising:
- a loaded monopole radiator including first and second conductors on a printed circuit substrate, said first conductor having a given length oriented in a first direction, said second conductor having a meander line shape and oriented in a second direction perpendicular to said first direction;
- and
- a ground radiator including a first radiating portion disposed on a first side of said second conductor, and a second radiating portion disposed on a second side of said second conductor, said first and second radiating portions being connected to each other.
