1. An antenna element comprising:

  • a multi-layer circuit board;

    a linked-ring conductive resonator located on a top layer of the multi-layer circuit board and comprising a plurality of ring elements connected by one or more tuning tabs;

    a first feed line and a second feed line located on a middle layer of the multi-layer circuit board and capacitively coupled to the linked-ring conductive resonator;

    an electromagnetically-shielding ground plane located on a bottom layer of the multi-layer circuit board; and

    a Faraday cage surrounding the linked-ring conductive resonator, the first feed line, and the second feed line and conductively coupled to the electromagnetically-shielding ground plane.
