CCDC ARL

A patch antenna system and method comprising a base extending in a first plane; at least one patch mounted in a plane substantially parallel to the first plane; spaced from the base by at least one metallic post such that between the base and patch is substantially only gaseous fluid (which may be air). At least one power source may be operatively connected to the at least one patch for generation of electromagnetic waves at a center frequency of approximately 5.8 Gigahertz. The method of neutralizing unattended microwave devices comprises connecting a power source to a patch antenna and operating the patch antenna at a frequency in the range of approximately 3.89 to of 5.85 Gigahertz in the vicinity of a suspected unattended microwave device used to activate an explosive device to thereby jam any communication signal to the unattended microwave device and prevent the activation.
