The present invention is directed to a fuze application capable of GPS
(Global Positioning System) and proximity radar functionality by
co-locating a proximity radar antenna with a GPS DRA (Dielectric
Resonator Antenna) fuze. The GPS DRA fuze has a HE.sub.11.delta. mode
structure resulting in an E-field null at the center. The monopole
proximity radar antenna is mounted in the E-field null center and is thus
electrically isolated from the GPS DRA fuze. The high dielectric constant
permits the GPS DRA fuze to operate in the L1 frequency and the
electrically shortened proximity radar antenna to resonate in the C-Band
within a small form factor. The GPS DRA fuze maintains a forward-looking
CP (circular polarization) pattern while proximity antenna maintains a
desirable monopole pattern. Nesting allows mounting of both GPS and
proximity radar antennas on the fuze nose while reducing the total space
occupied.
