The left and right sides of these two pads are perfectly symmetrical and do not distinguish between positive and negative and left and right.

Three matching devices together form π-type matching network for the impedance matching of A3216H2G50M200-03 patch antenna. The specific device values of these matching devices need to be obtained after antenna impedance matching and debugging. The device values shown above are the values of our test circuit board and can be used as reference values. If you do not have high requirements for antenna performance, you can also directly use the above reference values. The line width should match the 50 ohm characteristic impedance according to the PCB material and thickness design. It is recommended to place the antenna on the edge or corner of the board, do not place the antenna in the middle of the board and do not allow the antenna to be surrounded by conductors. Gaps are needed near the antenna area of the board. As shown above, the blank area on the board (the white area) is the gap area of the antenna. The so-called A3216H2G50M200- Guangdong Dongyou Technology Co., Ltd 03 clearance area refers to the area that cannot be paved and wired except for the antenna pad and antenna signal wiring. The clearance treatment of this area should be for all layers of the PCB board, not just the surface layer. The headroom area of the antenna should be as large as possible, and the antenna should be placed as close as possible to the edge of the board, so that the antenna body is far away from the board, and the larger the headroom means the better the antenna efficiency and gain performance. In the structure of the whole machine, it is recommended that there should be no conductor in the overhead area above or below the direction of overlooking the PCB, otherwise the antenna performance will be affected. The non-clearance area needs to be paved, and the ground should be increased as much as possible through the hole connection between the layers. A3216H2G50M200- Guangdong Dongyou Technology Co., Ltd 03 The equipment used for antenna matching debugging is the network analyzer. If you are an antenna professional technician, you can perform antenna matching debugging with the network analyzer that comes with you. If you do not have the relevant technology, please contact us and we can provide it for your product Professional antenna impedance debugging services. Antenna matching debugging needs to provide the entire product (no need to open it). Note that antenna impedance matching debugging mentioned here has nothing to do with RF line impedance control. Rf line impedance control is only for RF line wiring in paved areas, where the matched antenna impedance is the antenna. Please do not confuse the two. 2. The performance parameters of antenna matching after debugging are shown in the figure below: S11 Log Mag: A3216H2G50M200-03 Guangdong Dongyou Technology Co.,Ltd S11 Smith R+jx: A3216H2G50M200- Guangdong Dongyou Technology Co., Ltd 03 S11SWR: A3216H2G50M200- Guangdong Dongyou Technology Co., Ltd 03 Efficiency Peak Gain Directivity 2400MHz 55.21% 1.45 dBi 5.32 dBi 2450MHz 66.45% 2.71 dBi 5.21 dBi 2500MHz 57.53% 1.98 dBi 5.29 dBi A3216H2G50M200- Guangdong Dongyou Technology Co., Ltd 03 3, reliability and test conditions Items requirement TEST CONDITION Weldability test 1.
