Abstract:
Disclosed are multi-band trace antennas and circuit boards including a multi-band trace antenna for the transmission and/or reception of information in a wireless communication system. The circuit board is configurable to include a multi-band trace antenna. Additionally, the circuit board can comprise a feed point adjacent an edge of the circuit board, the feed point being connected to a pair of closely coupled traces of unequal length, a first of the traces extending away from the feed point along the edge of the circuit board, and a second of the traces extending away from the feed point inboard of the first antenna trace, the circuit board comprises a ground plane coplanar with the traces, an edge of the ground plane extending alongside and closely coupled with the second of the traces to cause an area of the ground place adjacent the edge to radiate at a selected lower operational frequency of the antenna, wherein an edge of a longer of the pair of closely coupled traces is indented to vary a width of the trace at a plurality of points along its length and to increase radiation of the shorter of the pair of closely coupled traces at a selected higher operational frequency of the antenna.
