An apparatus includes a stacked patch radiator having (i) a lower patch and (ii) an upper patch located above and separated from the lower patch. The upper patch includes first and second conductive patches that are separated from one another. The apparatus also includes a heating circuit integrated in the stacked patch radiator. At least a portion of the heating circuit is positioned between the first and second conductive patches of the upper patch. The stacked patch radiator can be configured to radiate at a specified frequency band and can have a thickness that is less than one tenth of wavelengths within the specified frequency band. The upper patch can include conductive vias electrically connecting the conductive patches. The conductive patches and the conductive vias can form an isolation cage configured to reduce a signal loss associated with a presence of at least the portion of the heating circuit between the conductive patches.

A sweatband for a hat, that can be easily inserted and removed, comprising a flexible retaining strip which permanently attached on one end to the inside surface of a hat, with the opposite end of the strip removably attached to the inside surface of the hat by means of a snap fastener, and a tubular sweatband, which, when the snap fastener is disengaged, can be inserted around the retaining strip, and thereby be retained in the hat when the snap fastener is engaged. The sweatband can also be easily removed to be cleaned or replaced by unfastening the removable end of the retaining strip.
