What is a horn antenna?
A horn antenna is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horn antennas are used as antennas at UHF and microwave frequencies that are above 300 MHz.
How horn antenna is fed?
Horn antenna are typically fed by a section of a waveguide, the waveguide itself is often fed with a short dipole.
What do you call a bug with a horn on top of its head?
An insects horn is called an antenna.
Which antenna is best guided by waveguide?
horn
Which antenna is best excited by a wave guide?
Horn Antenna is best exited by waveguide

Effects caused by opening angle of a pyramidal horn antenna?
The opening angle of a pyramidal horn antenna is to match the impedance of the horn antenna to that of free space. With this enlargement of the dimension, the velocity of the wave travelling will decrease. This will increase the guide wavelength, which in turn increases the impedance of the horn. This gives an impedance value closer to that of free space there by giving better power transfer.
Why might a parabolic reflector horn type microwave antenna be preferable to a parabolic dish type microwave antenna?
The reflector horn type antenna has greater "side lobe" rejection, directionality and sensitivity (efficiency) than a dish type.
