Abstract
A microstrip antenna located on a substrate with a first surface and a second surface opposite to the first surface includes a feeding portion, a grounding portion, and a radiating portion. The feeding portion is located on the first surface of the substrate to feed electromagnetic signals. The grounding portion is located on the second surface of the substrate. The radiating portion is located on the first surface and includes a first radiating part, a second radiating part, a third radiating part, and a fourth radiating part. Each of the first radiating part, the second radiating part, and the third radiating part is on a rectangle-shaped strip line. The first radiating part is connected to the feeding portion. The fourth radiating part is perpendicularly connected to a second end of the third radiating part.

A microstrip antenna located on a substrate having a first surface and a second surface opposite to the first surface, the microstrip antenna comprising:
- a feeding portion located on the first surface of the substrate, to feed electromagnetic signals;
- a radiating portion located on the first surface of the substrate, to radiate an electromagnetic signal, the radiating portion comprising:
- a first radiating part of rectangular strip with a first end connected to the feeding portion;
- a second radiating part of rectangular strip with a first end connected to a second end of the first radiating part, wherein a width of the second radiating part is greater than that of the first radiating part;
- a third radiating part of rectangular strip with a first end connected to a second end of the second radiating part, wherein a width of the third radiating part is the same as that of the first radiating part, and the first radiating part, the second radiating part, and the third radiating part are arranged in series;
- and
- a fourth radiating part of rectangular strip perpendicularly connected to a second end of the third radiating part, at a substantial center of the fourth radiating part;
- and
- a grounding portion located on the second surface of the substrate and rectangularly shaped.
