Planar antenna
First Claim
1. A planar antenna disposed on a substrate comprising a first surface and a second surface, the planar antenna comprising:
- a feeding portion laid on the first surface for feeding signals to the antenna;
a radiating body laid on the first surface for transmitting and receiving radio frequency (RF) signals, the radiating body comprising a meandering first radiating portion extending away from the feeding portion and a second radiating portion extending away from the feeding portion next to the first radiating portion, the first radiating portion comprising an open end disposed at an extending end thereof to point toward the second radiating portion and a connecting portion disposed at another end thereof, the second radiating portion comprising a free end disposed at an extending end of the second radiating portion to point toward the first meandering radiating portion and an end connected to the connecting portion, a first gap formed between the open end of the first radiating portion and the free end of the second radiating portion, and the open end, the first gap and the free end being aligned with one another; and
a first metallic ground plane, laid on the second surface of the substrate, the first ground plane electrically connected to the second radiating portion through a via.

Abstract
A planar antenna (20) includes a radiating body (21), a feeding portion (22), and a first metallic ground plane (24). The radiating body includes a first radiating portion (212) extending away from the feeding portion and a second radiating portion (214) extending away from the feeding portion next to the first radiating portion. The first radiating portion includes an open end (2122) disposed at an extending end of the first radiating portion to point toward the second radiating portion, and a connecting portion (2124). The second radiating portion includes a free end (2144) disposed at an extending end of the second radiating portion to point toward the first radiating portion, and an end (2146) connected to the connecting portion. A first gap (26) is formed between the open end and the free end. The open end, the first gap and the free end are aligned with one another.
