Abstract
A wideband dual-mode antenna comprising: a dielectric substrate; a conductive layer disposed on a first face of the dielectric substrate; two tapered slots separated from each other by a linear center conductor formed in the conductive layer, wherein the tapered slots narrow to slot-lines terminated by respective baluns at a feed end of the wideband dual-mode antenna; and wherein the two slot-lines follow paths that, at the feed end, transition from being parallel to the center conductor to following meandering paths that curve away from, and then back towards, the center conductor.

A wideband dual-mode antenna comprising:
- a dielectric substrate;
- a conductive layer disposed on a first face of the dielectric substrate;
- two tapered slots separated from each other by a linear center conductor formed in the conductive layer, wherein the tapered slots narrow to slot-lines terminated by respective baluns at a feed end of the wideband dual-mode antenna;
- and
- wherein the two slot-lines follow paths that, at the feed end, transition from being parallel to the center conductor to following meandering paths that curve away from, and then back towards, the center conductor.
A wideband dual-mode antenna comprising:
- a dielectric substrate having first and second faces, wherein the first and second faces are opposite to each other;
- a conductive layer disposed on the first face;
- two tapered slots formed in the conductive layer, wherein each tapered slot tapers from a mouth at an aperture end to a slot-line at a feed end;
- a center conductor formed in the conductive layer separating the two tapered slots;
- two micro-strip conductors disposed on the second face so as to feed the two tapered slots to form tapered slot antennas;
- and
- a conductive isolation boundary disposed on the second face opposite the center conductor and electrically connected to the center conductor through a series of vias in the dielectric substrate.
