The attenuators are basically passive devices which control power levels in microwave system by absorpsion of the signal. Attenuator which attenuates the RF signal in a waveguide system is referred as waveguide attenuator. There are two main types fixed and variable. They are achieved by insertion ...
The sweep speed refers to the time the vector network analyzer (VNA) requires to finish one sweep of the source signal and get all the selected data in a chosen frequency range. It is usually specified in terms of time per data point and the time required for a sweep is called cycle ti...
The idea of ports can be (and is) extended to waveguide devices, but a port can no longer be defined in terms of circuit poles because in waveguides the electromagnetic waves are not guided by electrical conductors. They are, instead guided by the walls of the waveguide. Thus, the concept...

conventions, microwave ovens at home or in restaurants operate at frequencies ofabout 2.45 GHz, i.e. λ = 12. 23 cm. Figure 1 depicts a typical microwave oven (many details can be found in [1–3]). Microwaves are generated in a magnetron which feeds via a waveguide into the cooking ...
of the waveguide. Thus, the concept of a circuit conductor pole does not exist in this format. Ports in waveguides consist of an aperture or break in the waveguide through which the electromagnetic waves can pass. The bounded plane through which the wave passes is the definition of the port...

A horn antenna mainly includes a flaring metal waveguide formed as a horn to direct radio waves within a beam. These antennas are used at microwave & UHF frequencies > 300 MHz. These antennas have a high gain of a directional radiation pattern that ranges from 10 to 20dB, in some cases,...
