- waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)
- horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide

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.
What are the uses of pyramidal horn antenna?
AnswerGAND MARAOpyramidal horn are antennas in which the walls of the rectangular wave guide are flarredin both e-plane & h-plane directions.applications:---> when there is a high gain requirement.--> when there is high directionality requirement.
What was the abeng made from?
a cow horn
When was the shoe horn invented?
1903
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.
Which antenna is best guided by waveguide?
horn
Which antenna is best excited by a wave guide?
Horn Antenna is best exited by waveguide
What are the practical applications of horn antenna?
microwave. it couples the waveguide to open space.
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.
What do you call a bug with a horn on top of its head?
An insects horn is called an antenna.

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.
Difference between gsm antenna and microwave antenna?
In GSM mainly using Panel type antennas but in the case of Microwave Antenna using Horn antennas. Microwave anteenas propogate signal straghtly. So line of sight (LOS) is main issue in the case of Microwave antenna, it means that both antennas must be allign in face to face. Microwave antennas are using for link between BTS but GSM antennas are directly link with customers. Antenna Gain also very much difference both cases. JPS o,[.[;.;[.]/]/ pppppppppppppppp
What are the disadvantages of horn ANTENNA?
Directional diagram width depends on the physical size of antenna. In order to get beam radiation antennas are made with a long horn. It's better when it is in proportion to an aperture square, i.e. of a peak cross-section LH or LE, and a directional diagram width is in inverse proportion to LH or LE in the first power.Therefore in order to make a directional diagram N times narrower the aperture width must be broadened by N times and the horn must be lengthened by N2 times. The horn must be excessively lengthened to get a higher gain which is very inconvenient. In this case mirrors and lenses are used in the horn aperture.Use of a horn as an irradiator of a parabolic antenna presents a whole new device which is distinguished for its narrow directional diagram and low level of side lobes.

Can a compression driver be used without a horn?
Yes. You can run one 'bare'. It will afffect response and efficiency. Some drivers can be found that spec traditional horns and also wave guides, which are not horns in the traditional sense. Do note, without the loading expected from the horn / waveguide, you will need to take care in input levels at low frequecies for the driver.
