    摘要: The present invention concerns a system of receiving signals comprising a retransmission base to amplify signals captured at a point in a domestic environment and retransmit them at the same frequency to digital receivers of the said domestic environment. According to the invention, the retransmission base amplifies and retransmits up to N DVB-T channels the positions of which can be anywhere in the receive band and are chosen dynamically by the system users. Means are provided in the system to share the system's amplification resources between the system's various digital receivers.

    摘要: The present invention relates to a compact planar antenna containing, on a substrate featuring at least one ground plane, a radiating slot forming at least one folded strand with parallel strand parts. The antenna contains at least one means of phase inversion between two successive strand parts, the means of phase inversion being positioned on the strand in such a manner that the field components of the parallel strand parts are added together. The use of phase inversion means makes it possible to reduce the dimensions of the antenna, facilitating its integration on a card.
