Abstract
An antenna includes a substrate, a radiation portion, and a signal feed-in portion. The radiation portion includes a first radiation unit and a second radiation unit. The first radiation unit and the second radiation unit are disposed on the same surface of the substrate. The signal feed-in portion is disposed on the first radiation unit. The second radiation unit and the first radiation unit have the same shape and are symmetrical in position, and the second radiation unit is connected to the first radiation unit, such that the first radiation unit and the second radiation unit form a closed loop. Thus, the impedance is improved and a wider bandwidth is achieved.
Claims17
An antenna, comprising:
- a substrate, having a surface;
- a radiation portions, comprising:
- a first radiation unit, disposed on the surface;
- and
- a second radiation unit, disposed on the surface to serve as a ground unit, wherein the second radiation unit and the first radiation unit have a same shape and are symmetrical in position, and the second radiation unit is connected to the first radiation unit, such that the first radiation unit and the second radiation unit form a closed loop;
- and
- a signal feed-in portion, disposed on the first radiation unit, for feeding in/out a signal.
An antenna, comprising:
- a substrate, having a first surface and a second surface, wherein the first surface has a first circuit, and the second surface has a second circuit overlapping the first circuit;
- a main signal feed-in portion, disposed on the first circuit and the second circuit, for feeding in/out a signal;
- a plurality of radiation portions, each comprising:
- a first radiation unit, disposed on the first surface and electrically connected to the first circuit;
- and
- a second radiation unit, disposed on the first surface to serve as a ground unit, wherein the second radiation unit and the first radiation unit have a same shape and are symmetrical in position, and the second radiation unit is connected to the first radiation unit, such that the first radiation unit and the second radiation unit form a closed loop;
- and
- a plurality of sub-signal feed-in portions, disposed on the second circuit and the first radiation unit, for feeding in/out the signal.
