Na njedebe nke ọnwa Febụwarị, Raytheon ekpughere ihe ngosi radar mgbochi mgbochi ụgbọ elu Patriot nke nwere antenna nyocha izizi na-arụ ọrụ (AFAR) nwere modul transceiver nke ejiri teknụzụ gallium nitride (GaN). Nke a bụ nzọụkwụ na-esote maka mmepe nke ọdụ ụgbọ elu nke nwere antennas GaN AESA nwere ike ilele anya n'ime radius 360 °, nke ụlọ ọrụ Poland tụpụtara, n'etiti ihe ndị ọzọ, dịka akụkụ nke ngwa Patriot NG na-ekwe nkwa.
N'oge oyi gara aga, Raytheon bipụtara foto mbụ nke ihe nlereanya nke antenna radar Fire Control Patriot NG. N'oge okpomọkụ nke 2015, ndị nta akụkọ Polish nwekwara ohere ịmụta banyere nke a.

Radar ndị dị na mgbagwoju anya nwere antenna passive (PESA) na modul transceiver mere site na iji teknụzụ gallium sulfide (GaS). Antenna na-arụ ọrụ na-enye gị ohere ijikwa ike, ọdịdị na ọnọdụ nke radieshon radieshon. Mgbakwunye nke antenna abụọ dị otú ahụ a na-agbanye n'elu akpa ngwá ọrụ radar kwesịrị inye nchọpụta gburugburu gburugburu, ya mere onye ọ bụla kwesịrị inwe mpaghara nlele opekata mpe 120 Celsius (o doro anya na antennas akụkụ nwere nlele nke 150 °).
