Embodiment 2
[0036] Such as Figure 8 As shown, the main difference between the printed antenna of this embodiment and Embodiment 1 is that the overall structure of the first radiation unit 3 in this embodiment is an approximately rectangular structure.
Embodiment 3
[0038] Such as Figure 9 As shown, the main difference between the printed antenna of this embodiment and Embodiment 1 is that the overall structure of the first radiating unit 3 and the second radiating unit 4 in this embodiment is an approximately elliptical structure.
[0039] The same simulation test as in the first embodiment is carried out on the printed antennas of the second and third embodiments, and the test results are roughly the same as those of the first embodiment.

Description
technical field [0001] The invention relates to the technical field of printed antennas, in particular to a high-gain printed antenna. Background technique [0002] With the development of wireless communication technology, users can use wireless communication to transmit information without being restricted by terrain, and antennas are one of the important components in the field of wireless communication. Traditional antennas are dipole antennas, helical antennas, Yagi antennas occupy quite large volumes, which are no longer in line with current trends and trends. Therefore, in recent years, the industry has applied the principle of Pinghe antennas to design smaller and thinner printed antennas. The antennas are small in size and low in cost, and can be Applied in various fields. [0003] With the improvement of the integration of electronic equipment, communication equipment has higher and higher requirements for antennas. In the past, the gain of the printed broadband ...
