Printed circuit board antenna

摘要

The antenna consists of a multilayer printed circuit board (LP) which has at least two interconnected layers (L1...L4). Their surfaces (E1...E5) have conductor tracks applied to them in such a manner that flat coil elements (S1...S5;P1...P5) are produced. The coil elements are embedded, located as far as possible one above the other, inside the multilayer printed circuit board (LP) and are connected together in series with the aid of through-plated holes (D,D1...D4) to form a multilayer antenna (SP;EP). Coil elements (S1...S5) which are separated per layer (L1...L4) and are preferably located concentrically within one another are preferably provided for a transmitting antenna (SP), and coil elements (P1...P5) for a receiving antenna (EP).
