Abstract:
1. An apparatus, comprising: at least one electrically insulative substrate; and a first plurality of antennas distributed along at least a portion of the at least one insulative substrate, each antenna comprising a plurality of elongated segments and a plurality of jog segments electrically coupled in series to one another, each jog segment coupling successive elongated segments to one another and being oriented at an angle relative to elongated axes of the two corresponding successive elongated segments, and the elongated and jog segments of each antenna carried on at least two different layers of the insulative substrate and electrically connected through at least one via, and where the elongated and jog segments of each antenna on a first layer are laterally spaced apart from one another with respect to a longitudinal axis of the segments to form gaps between successively adjacent ones of the elongated and jog segments on the first layer, and the elongated and jog segments of each antenna on at least a second layer laterally spaced apart from one another to form gaps between successively adjacent ones of the elongated and jog segments on the second layer, the elongated and jog segments on the second layer located directly below the gaps formed between the successively adjacent ones of the elongated and jog segments on the first layer, and where a number of jog segments on the first layer overlap with a number of jog segments on the second layer and the only overlap of segments on the first and second layers is at these number of jog segments and at the at least one via.
