Some fancy antennas do not require that you add a ground plane.
Gps antenna metal sheet or not.
Ism gps bt stamp metal ethertronics antenna specifications gps single band antenna ethertronics produces a wide variety of standard and custom antennas to meet user needs.
Pin 1 50ω transmission line pin 3 pin 2 r1 r2 r3 r4 through hole through hole antenna outline vias.
Low band main antenna implementation.
Route through a 3 4 inch drilled hole into the building.
Transmitter with internal antenna.
The gps antenna was integrated into the top metal frame above the watch lower metal frame and utilized the system ground which was encircled by the said lower frame as part of the loop resonant path.
This mount is suggested only if you used a heavy enough gauge sheet metal for the ground plane the thin hardware store variety aluminum will buckle and throw the antenna off its vertical axis.
2 4 ghz wifi sheet metal antenna sz0401c.
Route through a 5 8 inch drilled hole into the building.
3mm at the bottom and 3 4mm on the sides at the farthest point antenna pattern made with lds and covered with visual painting.
Placement of the gps antenna is crucial to the quality of the data recorded.
Antenna solution for full metal mobile device chassis metal box construction.
If there is no flat metal surface to mount the antenna you can create a ground plane by putting a 12 22cm diameter metal sheet directly below the antenna about 1 2 the signals wavelength which gives 1 4 wavelength per side.
Assemble and mount the gps receiver unit to either the inside of a window not low e glass or to an outside pole or rooftop.
Do not mount the antenna close to the edge of the roof as reflections from the ground may interfere with the signals.
Transmitter with external antenna.
The best solution is to have a dome or even hemispherical radome made from the best thin dielectric.
A gps antenna needs to operate with signals from as low as 10 degrees above the horizon 80 degrees from normal incidence and at this angle even a thin sheet of plastic has a significant effect.
Antennas are located around the device with minimal ground clearance ground clearance.
