An electronic device may include a millimeter wave antenna having a ground plane, resonating element, feed, and parasitic element. The resonating element may include first, second, and third layer of traces that are shorted together. The second traces may be interposed between the first and third traces and the third traces may be interposed between the second traces and the parasitic. The third traces may have a width that is less than the widths of the second and third traces. The third traces and the parasitic may define a constrained volume having an associated cavity resonance that lies outside of a frequency band of interest. If desired, the resonating element may include a single layer of conductive traces having a grid of openings that disrupt impedance in a transverse direction, thereby mitigating the trapping of energy within the frequency band of interest between the resonating element and the parasitic.

Various embodiments that relate to a circular disk configured to radiate a signal. The radiating disk can include edge openings. Within these edge openings power supplies can rest. When the power supplies function, they can cause the circular disk to radiate with either a dipole pattern or a cardioid pattern. A controller can manage how these power supplies function depending on if the dipole pattern or the cardioid pattern is desired.
