ABSTRACT
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 (L5 band), 1227 MHz (L2 band), and 1575 MHz (L1 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.
