Modernization of the GPS system that is currently underway will require future GPS antennas to operate at three separate frequency bands centered around 1176 MHz (L 5 band), 1227 MHz (L 2 band), and 1575 MHz (L 1 band). A compact, low‐profile, right‐hand circularly polarized (RHCP), four‐element antenna array of trap‐loaded inverted L elements, capable of providing good gain coverage at all three frequency bands over the required bandwidth, is described in this paper. © 2003 Wiley Periodicals, Inc.
