Radio antenna for mobile communications transmitter has active vertical rectangular radiating surface held on earthed spacers and has high-frequency connector extending toward circuit board

摘要

The mobile communications transmitter radio antenna is mounted on a rectangular circuit board (BD2) near one corner. It has an active vertical rectangular radiating surface (VP1) held on earthed spacers. It extends parallel to the long sides of the circuit board and has a high-frequency connector extending toward circuit board. An antenna volume (EV2) surrounds the radiating surface.
