A small tri-band GPS antenna is proposed as part of an anti-jamming GPS array. A key aspect of the element is its single feed to achieve circular polarization even when integrated in a small array. This is done via a Wilkinson powder divider together with a quarter-wavelength delay line. Different array configurations are studied to minimize coupling. Design procedures are presented along with the measurement validations. © 2008 IEEE.
