Dual-band antenna with three resonators
First Claim
1. An antenna comprising:
- a conductive ground plate;
a conductive first plate set above the ground plate, a fixed distance separating the first plate and the ground plate, the first plate comprising;
first, second, and third resonance regions with respective dimensions corresponding to wavelengths of first, second, and third frequencies at which the antenna operates; and
a connection region connected to the first, the second, and the third resonance regions;
a conductive connector having two opposite ends respectively connected to the ground plate and the connection region; and
a signal feeder having two terminals respectively electrically connected to the ground plate and the first plate;
wherein the first, the second, and the third frequencies are different, the first, the second, and the third frequencies respectively corresponding to first, second, and third frequency bands of the antenna, the second frequency being close to the third frequency such that the second frequency band and the third frequency band are partially overlapped to cause the second frequency band and the third frequency band to merge.

Abstract
An antenna comprises a ground plate, a first plate, a connector, and a signal feeder having two terminals respectively electrically connected to the ground plate and the first plate. The first plate is set above the ground plate and comprises first, second, and third resonance regions with respective dimensions corresponding to wavelengths of first, second, and third frequencies at which the antenna operates. A connection region is connected to the first, second, and third resonance regions. The connector has two opposite ends respectively connected to the ground plate and the connection region. The first, second, and third frequencies respectively correspond to first, second, and third frequency bands of the antenna. The second frequency is close to the third frequency such that the second frequency band and the third frequency band are partially overlapped to cause the second frequency band and the third frequency band to merge.
