Abstract: Described herein are systems for radio-frequency (RF) localization. The systems developed by the inventors are designed to improve the accuracy of RF localization to millimeter and sub-millimeter ranges, and additionally, are designed to do so while also limiting manufacturing costs. The RF localization systems developed by the inventors leverage the relatively low costs associated with the manufacturing of printed circuit board assemblies (PCBAs). Manufacturing RF localization devices using PCBAs poses a number of challenges, including large minimum feature size and the presence of surface waves. Described herein are techniques for addressing challenges arising in connection with RF localization devices fabricated using PCBAs. One technique involves the use of slot-fed antennas, which makes the device efficient notwithstanding the large minimum feature size. Another technique involves the use of frequency selective surfaces for suppressing surface waves.
