Outdoor application and knowledge of WiFi antenna
Author:
The antenna equipment has high reliability, extremely low repair rate, and almost no protection cost; it is suitable for outdoor harsh environments and can complete non-line-of-sight transmission.
The guarantee of the built-in antenna performance has strict structural requirements. The basic requirements are as follows, otherwise the antenna performance will be greatly affected. The specific impact depends on the type of antenna. It is generally believed that the PIFA antenna is large in size and good in performance; the sliding cover machine must be designed with this kind of antenna.
The specific requirements are as follows: 1 The height of PIFA should be no less than 6; the nnetr of LCM should be laid out on the keyboard surface of the motherboard; 3 the width of the antenna should be no less than 0; 4 the impedance of the lead from the RF test port to the antenna feed point should be kept at 0 ohm ; The components near the PIFA antenna should be shielded as much as possible; 6 The pad of the feed point should not be less than *3; 7 The pad of the feed point should be on the top * side; 8 If the layout of the test socket is difficult, you can also put it In the antenna area; 9 Some positioning holes can be properly opened in the antenna area. 10 There should be no large metal objects such as motors, SPEAKE, ECEIVE, etc. within 7 mm of the built-in antenna
