Wifi antenna shield

Shielding protects against both leakage and absorption of stray radiation of electrical noise by cables. While insulation protects antenna cables from physical damage due to the forces of impact or compression, it is shielding which deflects the environmental challenges of EMI electromagnetic interference.

Where there are appliances with heavy transference of charge, like transformers for example , high levels of EMI radiation should be expected. No shield protection within cabling is impenetrable, but the aim is to sufficiently dampen attenuate the noise, such that it doesn't interfere with the signal carried.

Shielding methods vary. Increased shielding is called for in especially noisy environments challenged with many sources of high load interference and the converse is expected in lesser noisy locations. Shielding reduces flexibility and increases the diameter of cables. This becomes an issue in tight spaces, such as device cases and enclosures.

Cable shielding comes at budgetary cost, so a carefully calculated trade-off should be considered. Too bad the forum won't provide bookmark and I just have to reply in order to keep it in my list of posts. Thanks CrossRoads! It's good to know there is such option. I am working on a project that will likely have one wifi hotspot and several arduinos with wifi shields. I could give this a try. I got cold feet on making the changes to the board as I only have one which I need and can't chance messing up, however this document pertains to the possibility of adding a connector for an external antenna :.

Could anyone advise if this is possible, and how exactly I could do it? Thank you for the quick reply. This is the antenna I want to connect to it : Part No. Badges: Odd question for you. I'm replacing the antena in a nvidia shield as an experimant, as was wonder if you know what type of connecter is used on the cable to the pcb.

I dont want to desoder the exsisting antenna if i can help it as they are calabrated. Fix Your Stuff Community Store. Difficulty Moderate. Steps 6. Time Required 30 seconds. Sections 2. Flags 1. Better Introduction Improve this guide by completing or revising its introduction.
