Correct. They're microwave horn antennas with direct-coupled magnetrons (no waveguide included). Since he has two, they likely came from somebody's local 2-way datacomm app.
(If the two "narrow" sides were parallel instead of just almost, they would be sectoral horns [in an industry that has a very clear definition of the term]).

Sorry guys you are all wrong, I have seen them before, these are electric umbrella dry stands.
My old Whirlpool Microwave doesn't have an antenna........ if I add these will my food re-heat faster?

Correct. It has an unterminated waveguide for broad distribution at close range. You might call it a "nearfield" application...
