Abstract:
An antenna for transmitting and receiving electromagnetic energy, said antenna comprising:a longitudinally extending housing having a first end and a second end, and defining an interior therebetween; a dielectric material configured with a slot therein and disposed at least partially within said interior of said longitudinally extending housing such that said longitudinally extending housing and said dielectric material form a dielectric-filled waveguide; and an element feed disposed at least partially within said interior of said longitudinally extending housing and surrounded at least partially by said dielectric material, comprising: a first transition from a first section of a microstrip transmission line not disposed within said housing to a pseudo-stripline transmission line, wherein said pseudo-stripline transmission line comprises a second section of said microstrip transmission line disposed within a first section of said housing that is not filled with said dielectric material; a second transition from said pseudo-stripline transmission line to a pseudo-slotline transmission line, wherein said pseudo-slotline transmission line comprises a third section of said microstrip transmission line disposed within a second section of said housing that is filled with said dielectric material; and a third transition from said pseudo-slotline transmission line to a first and a second opposing flare extending from said pseudo-slotline transmission line to within said interior of said longitudinally extending housing, wherein said element feed is configured to transfer electromagnetic energy between said antenna and a transmission line.
