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 ...
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...
The antenna(s) can be connected to the processor of the input device. Bidirectional communication between the input device and the control device is possible. In the case of unidirectional and/or bidirectional communication between the input device and the control device, a gateway can be (inter...
