S11 (return losses) is another expression for SWR (standing waves ratio) and IMO a better one. It is the ratio of port #1 to port #1, in other words, what comes out of port #1 relative to what you injected in port #1. When you send power to an antenna, some of it is reflected […]
This is an aircraft light I designed a few years back. I decided to make a tutorial for it so others can make and hopefully continue to improve the design. The light is base around CREE’s XM-L or XHP-70 LED. Supply list: CREE X-ML2 or XHP70 mounted on 20mm copper MCPCB. 20x20mm star shaped heat-sink. […]
We designed the new micro AXII for lumenier. A move forward from the current AXII in term of miniaturization at less than half the volume of the original. By far, the smallest 5.8GHz CP antenna available right now. In order to bring the micro AXII, innovations going beyond RF engineering had to be made, such […]
Mishaps. They always happen, no one escape. When your singularity antenna is smashed by an unfortunate event, not all hope is lost! With a 3D printer and basic soldering skills you can salvage your dead antenna and turn it into a “polarizer”. First, tear away the ends caps, then un-solder the network. The elements […]
Above is a radiation pattern from an omni directional antenna (AXII) typically found on aircraft transmitter. The usual dBi unit been replaced by ratio of maximum range. You may ask why we didn’t simply marked in meters or kilometers? Because the ultimate range depends on a lots of others factors than one antenna. However, keeping […]
Thanks to the FPV community’s strong support, we continued R&D work on our ever popular directional CP antenna line on 5.8GHz, namely, the X-air 5.8, X²-air 5.8 and gatling 5.8. The results comes in more available circularity in the 5.8GHz region and even down to 5GHz! Circularity is also further increased at the beam’s edges. […]
Flying a RC airplane over water is a lot of fun, add FPV to it and it become really exciting. A descent water body means plenty of open space to take-off, fly and touch-down. Before starting the FPV water plane adventure there’s a few things to consider. What type of plane? How do you protect […]
We have upgraded to the latest tool in 3D EM (time domain) simulation. Expect even more and faster products development. Our capacity include but not limited to: Wire antennas Micro-strips antennas Micro-strips transmission lines Wave guides Electronic circuits boards Arbitrary 3D structures Broadband/steady-states calculations 2D/3D CAD import/export Also expect studies of many real world cases […]
I am extremely proud to present this whole new CP omni antenna design from TrueRC Canada.
