Description
Technical Field
The invention relates to a 5G medium-frequency small-size PCB antenna, in particular to a 2G, 3G and 4G compatible 5G medium-frequency small-size PCB antenna.
Background
Worldwide, mobile communication is rapidly transitioning from the second generation (2G), the third generation (3G), to the fourth generation (4G). The development of 4G communication is on the move and is rapidly being applied to various communication fields, such as internet of vehicles, internet of things, etc. Meanwhile, the fifth generation communication (5G) is now a research hotspot, and the middle frequency band of 5G, namely 3.4-3.6GHz and 4.8-5.0GHz, has just been determined by the china industry and informatization department. In response to the development of fifth generation communication (5G), related devices requiring 5G communication, a 5G antenna is now an important point of development.
At present, the industry does not have small-size PCB antennas compatible with the frequency bands of 2G, 3G, 4G and 5G at the same time, namely small-size PCB antennas with the frequency coverage of 824-960MHz/1710-2690MHz/3.4-3.6GHz/4.8-5.0 GHz.
Disclosure of Invention
The invention aims to provide a 2G, 3G and 4G compatible 5G medium-frequency small-size PCB antenna.
The invention adopts the following technical scheme:
the utility model provides a compatible 2G, 3G and 4G's 5G medium frequency small-size PCB antenna, includes FR4 double-sided copper-clad PCB board (dielectric constant is 4.4, dielectric loss is 0.02), double-sided copper-clad PCB board thickness is 1 millimeter, and length is 104 millimeters, and width is 8 to 13 millimeters.
The one-sided copper-clad area of the double-sided copper-clad PCB comprises a first part of an antenna radiator 1, a radiator 2, an antenna ground and an inductor, wherein a gap with the width of 1 millimeter is formed on the antenna ground.
The other side of the double-sided copper-clad PCB comprises a second part of the antenna radiator 1, a feed microstrip line and a capacitor.
The first part and the second part of the antenna radiator 1 are directly connected through a via.
And the feed microstrip line is connected with the other side of the double-sided copper-clad PCB through a via hole.
The performance of the low frequency part of the antenna, i.e. the 824-960MHz band, is determined by the antenna radiator 1 and the antenna ground, like a dipole antenna. The radiator 2 mainly determines 1710-2690MHz band performance, while the second harmonic of the low frequency also contributes to high frequency performance. The series lumped parameter inductor is mainly used for improving the standing wave ratio of high frequency. And the slot is for generating resonance in the 4.8-5.0GHz band. The feed microstrip line is used for feeding the slot and adjusts the matching of the antenna through the length and the width of the tail part of the feed microstrip line. The capacitor is used for isolating the 4.8-5.0GHz frequency band from other frequency bands so as not to influence each other.
The antennas cover the 2G, 3G and 4G frequency bands, i.e., 824-960MHz/1710-2690MHz, while covering the 5G mid-band, i.e., 3.4-3.6MHz and 4.8-5.0GHz. So the antenna supports 4G and 5G frequency bands on the basis of supporting traditional 2G and 3G communication.
Fig. 2 is a simulated antenna return loss plot. It can be seen from fig. 3 that the return loss is substantially less than-5 dB in the low frequency band and less than-6 dB in the 1710-2690MHz frequency band. The return loss of the frequency bands of 3.4-3.6GHz and 4.8-5.0GHz is less than-9 dB.
FIG. 3 is a voltage standing wave ratio diagram of an antenna, the voltage standing wave ratio being less than 4.0 in the 824-960MHz band, and less than 3.0 in the 1710-2690MHz band; the voltage standing wave ratio of 3.4-3.6GHz and 4.8-5.0 frequency bands is less than 2.0.
Fig. 4-7 are 3D gain radiation patterns for the antenna at 900MHz, 2.0GHz, 3.5GHz and 4.9GHz frequencies, respectively. It can be seen from the figure that the antenna has better performance at both low and high frequencies.
The beneficial effects of the invention are as follows:
1. the antenna is a 5G medium-frequency antenna, and meanwhile, 2G, 3G and 4G frequency bands are considered.
2. The antenna has good radiation performance, the gain of the antenna is more than 1dBi at low frequency (824-960 MHz), the gain of the antenna is more than 2.0dBi at high frequency 1710-2690MHz, and the gain of the antenna is more than 2.0dBi at 5G frequency band.
3. The antenna size is small, and the antenna size is 104 mm in length, 1 mm in thickness and 13 mm in width.
