Dual-band antenna having high horizontal sensitivity
First Claim
1. A dual-band antenna, comprising:
- a grounded conductor disposed over a support base;
a first radiating conductor plate that is disposed substantially parallel to the grounded conductor;
a first feeding conductor strip extending downward from the first radiating conductor plate;
a connecting conductor strip for connecting the first radiating conductor plate to the grounded conductor; and
a second radiating conductor plate oriented orthogonally to the grounded conductor and disposed between the grounded conductor and the first conductive radiating plate, wherein a lower end of the second radiating conductor plate is linked to a grounded conductor end of the first feeding conductor strip by a second feeding conductor strip.

Abstract
A dual-band antenna is described that includes a grounded conductor over a support base; a first radiating conductor plate that is disposed substantially parallel to the grounded conductor; a feeding conductor strip that extends downward from the first radiating conductor plate; a connecting conductor strip for short-circuiting the first radiating conductor plate to the grounded conductor; a second radiating conductor plate that stands vertically to the grounded conductor below the first radiating conductor plate; and a bridge for linking the lower end of the second radiating conductor plate to the lower end of the feeding conductor strip. Supplying high-frequency power having a first frequency to the lower end of the feeding conductor strip causes the first radiating conductor plate to radiate electromagnetic energy at the first frequency; supplying high-frequency power having a second frequency, which is higher than the first frequency, to the lower end of the feeding conductor strip causes the second radiating conductor plate to radiate electromagnetic energy at the second frequency.
