Several (in some cases many dozen) small antennae are integrated into or over a full body suit or clothing. These antennae preferably include an intra-suit or clothing wired connection to one or more small Ultra-Wide-Band (UWB) radios, e.g., in the 3-10 GHz range. In some cases, each antenna connection includes a variable delay, e.g., a few nanoseconds with picoseconds-scale resolution on the delays, thus allowing for the body-suit ensemble to act as a directional phased-array. One claim recites a radio wearable by a human comprising: a phased-array antenna including a plurality of antennae, the array being configured for wearing over or on a human body, the plurality of antennae provided for spatially positioning in multiple different regions over or on the human body; an RF radio; and a controller configured for: i) determining relative spatial position information for antennae within the phased-array antenna; and ii) using at least the relative spatial position information, controlling the radio to produce a directional UWB beam through the phased-array antenna. Another claim includes an antenna having a plurality of metamaterial elements. Of course, other claims and combinations are provided as well.
