Abstract: An antenna array that utilizes ground guard rings and metamaterial structures is disclosed. In certain embodiments, the antenna array is constructed from a plurality of antenna unit cells, wherein each antenna unit cell is identical. The antenna unit cell comprises a top surface, that contains a patch antenna and a ground guard ring. A reactive impedance surface (RIS) layer is disposed beneath the top surface and contains the metamaterial structures. The metamaterial structures are configured to present an inductance to the patch antennas, thereby allowing the patch antennas to be smaller than would otherwise be possible. In some embodiments, the metamaterial structures comprise hollow square frames. An antenna array constructed using this antenna unit cell has less coupling than conventional antenna arrays, which results in better performance. Furthermore, this new antenna array also requires less space than conventional antenna arrays.

Abstract: An electromagnetic pulse detector in an integrated circuit includes one or more peak hold circuits coupled to one or more traces in the integrated circuit and configured to asynchronously detect voltage spike(s) on the one or more traces and store voltage value(s) corresponding to the voltage spike(s). One or more comparator circuits are coupled to the peak hold circuits to compare the voltage values corresponding to the voltage spikes to one or more threshold voltage values. Storage locations are coupled to the comparator circuits to store indications of the voltage spike(s) being greater than the threshold voltage value to thereby indicate detection of an electromagnetic pulse.
