1. An electromagnetic antenna comprising:
a channel configured to serve as a waveguide for electromagnetic radiation;
a first and second feed disposed next to each other inside the channel at a first end thereof, the first and second feed being configured to radiate electromagnetic waves into the channel;
an aperture lens disposed inside the channel near a second end thereof opposite to the first end, the aperture lens being configured to output collimated beams;
a first focal lens disposed inside the channel adjacent to an outlet of the first feed, the first focal lens being configured to squint a beam radiated from the first feed toward a center of the aperture lens; and
a second focal lens disposed inside the channel adjacent to an outlet of the second feed, the second focal lens being configured to squint a beam radiated from the second feed toward the center of the aperture lens.
