waveguides are used instead of coax because at the high microwave frequencies coax would radiate the signal right through its shield.
waveguides do not replace antennas.
3 types: 1.electromagentic waveguides 2.optical waveguides 3.acoustic waveguides
thats a hard question
It is a waveguide that is circular. Circular waveguides have modes that are described in terms of Bessel functions instead of the sines/cosines used for rectangular waveguides. The disadvantage is that the two lowest modes have cutoff frequencies spaced by less than an octave. Circular waveguides are used for rotating joints, for example in radar. The H01 mode in circular waveguide was used as a low-loss mode for transmitting signals over distance, but this technique has been replaced by fibre-optic cables.
Circular waveguides are commonly used in various applications such as microwave communication systems, radar systems, and satellite communications. They are also used in medical imaging technologies like MRI machines and in industrial applications for non-destructive testing using electromagnetic waves. Circular waveguides are preferred over rectangular waveguides in high-frequency applications due to their ability to carry higher power levels with lower losses.
Because frogs do not have antennas
three basic types of antennas are: omnidirectional; semidirectional and highly directional antennas. typically when you purchase wireless access point and wireless NIC it has attached 2.14dbi omnidirectional antennas
Cisco antennas are used to stream internet signals to locations that would be difficult to route cables to. The internet signals used by Cisco antennas are between a 2.4-5 GHz range.
A microwave detector, also known as a microwave sensor or microwave receiver, is used to detect microwaves. These detectors typically consist of various components such as antennas, waveguides, diodes, and amplifiers that together can sense and measure microwave radiation.
Yes.
Digital antennas usually cost around $40. However you can find cheaper digital antennas that are used.
