Ahh, the good old quarter wave ground plane! This calculator can be used to design a Quarter Wave Ground Plane antenna, with radials. The radiating element is a quarter wave (λ/4) and the radials are 12% longer. There are usually four radials, three being a minimum, but you could ...
antenna. However, it can also be provided that at least one antenna is provided for one direction (from the input device to the control device and vice versa) and that different antennas are used for the two directions. The antenna(s) can be connected to the processor of the input device...
A land-based Global Navigation Satellite System (GNSS) product had two circular PCBs, each having a bottom layer dedicated to a solid 0V plane. One PCB carried the GNSSantenna/receivermodule on its top side, and the other carried the rest of the digital circuit on its top side. These...
