What is microstrip line in microwave?
Microstrip is a type of electrical transmission line which can be fabricated with any technology where a conductor is separated from a ground plane by a dielectric layer known as the substrate. Microstriplines are used to convey microwave-frequency signals.
Why is the microstrip line is preferred for RF microwave circuit board?
Probably the main advantage of microstrip historically is the ability to use just a 2 layer board, with all components mounted on one side. This simplifies both the fabrication and assembly processes and is the lowest cost RF circuit board solution.
How is a microstrip line constructed?
A microstrip transmission line is a “high grade” printed circuit construction, consisting of a track of copper or other conductor on an insulating substrate. There is a “backplane” on the other side of the insulating substrate, formed from a similar conductor.
Where are microstrip lines used?
Microstrip line is used to carry Electro-Magnetic Waves (EM waves) or microwave frequency signals. It consists of 3 layers, conducting strip, dielectric and Ground plane. It is used to design and fabricate RF and microwave components such as directional coupler, power divider/combiner, filter, antenna, MMIC etc.
Which are the types of microstrip lines?

What are the types of transmission lines used in microwave communication?
Microwave Engineering – Transmission Lines
- Two-wire parallel transmission lines.
- Coaxial lines.
- Strip type substrate transmission lines.
- Waveguides.
What are the example of discontinuities in microstrip?
Some of the most common forms of microstrip discontinuities are open ends, gaps, steps in width, right-angled bends, T junctions, and cross junctions.
What is characteristic impedance microwave?
If a uniform lossless transmission line is considered, for a wave travelling in one direction, the ratio of the amplitudes of voltage and current along that line, which has no reflections, is called as Characteristic impedance.
What are the various types of transmission lines?
Types of transmission line include parallel line (ladder line, twisted pair), coaxial cable, and planar transmission lines such as stripline and microstrip. The higher the frequency of electromagnetic waves moving through a given cable or medium, the shorter the wavelength of the waves.
