An antenna system comprising a first multi-layer Printed Circuit Board having multiple antenna elements disposed thereon, at least a second multi-layer PCB, which is mounted below the first multi-layer PCB, and which comprises electronic components for processing Radio Frequency signals received by the antenna elements; and multiple RF transitions, which are mounted between the first and second multi-layer PCBs and are operative to transfer the RF signals from the first multi-layer PCB for processing by the electronic components in the second multi-layer PCB.

Flat mobile antenna system

An antenna has stacked grounded metal plates with openings () and antenna layers () with feed lines (B,B), situated between grounded metal plates. The openings in the grounded metal plates are arranged as matrix of columns and rows. The ends of the feed lines (D,D) are aligned with the plate's openings (A) in order to form radiating elements. The plate () is placed below the bottom grounded plate (). The three-plate stack is arranged as two antenna packages (Apand Ap). These packages include also a layer () comprising active devises for initial amplification of the received signal, which are connected to the groups of radiating elements (D,D,A) through coaxial transitions (). As well as a combiner block () is connected to the active layer (). The antenna layers () are arranged in subarrays and the antenna output is connected by a transition () to a standard twin Low Noise Block.
