ABSTRACT:
A parasitically coupled, complementary slot dipole antenna element includes a driven, cavity-backed slot antenna element and a parasitic dipole element transverse to the slot of the cavity-backed slot antenna element. The cavity-backed slot and parasitic dipole antenna elements resonate at about the center frequency of the excitation signals supplied to the cavity-backed slot antenna element in order to generate a relatively symmetrical electromagnetic signature and an increased bandwidth.
