What is coplanar waveguide feed?

Coplanar waveguide is a type of electrical planar transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. On a smaller scale, coplanar waveguide transmission lines are also built into monolithic microwave integrated circuits.

What is coplanar waveguide fed antenna?

Coplanar waveguide is a kind of planar transmission line structure [8]- [16], whose ground and radiation patch are on the same layer of medium plate. Various types of coplanar waveguide feed antenna have been reported to achieve the goal of multiband, broad band and miniaturization [17] – [23].

What is coplanar antenna?

The coplanar patch antenna consists of a patch surrounded by closely spaced ground conductor and a CPW feed line, which has a similar geometric configuration as the loop slot antenna.

What are the advantages of CPW over microstrip line?

The advantages of coplanar waveguide are that active devices can be mounted on top of the circuit, like on microstrip. More importantly, it can provide extremely high frequency response (100 GHz or more) since connecting to CPW does not entail any parasitic discontinuities in the ground plane.

What is coplanar example?

Points or lines are said to be coplanar if they lie in the same plane. Example 1: The points P , Q , and R lie in the same plane A . They are coplanar .

What is coplanar and non coplanar?

Coplanar and Non Coplanar Points The points that lie on the same plane are called coplanar points and hence the points that do NOT lie on the same plane are called non-coplanar points. We know that two points in 2D can always pass through a line and hence any two points are collinear.

Why is waveguide pressurized?

The environment within a waveguide is under positive pressure. This pressurization serves to ensure that the waveguide leaks out rather than in and prevents vapor, dust and other particulates from entering the waveguide.

How does a stripline work?

A stripline is a type of transmission line based on planar microwave circuitry. It typically consists of a conducting strip surrounded by dielectric material and sandwiched between two conducting ground planes.

What are the applications of a coplanar waveguide resonator?

Coplanar resonators can also be employed as quantum buses to couple multiple qubits to each other. Another application of coplanar waveguides in solid state research is for studies involving magnetic resonance, e.g. for electron spin resonance spectroscopy or for magnonics. Coplanar waveguide resonators have also been employed to characterize

What is the original name for coplanar waveguide?

C.P. Wen explains that his original name for coplanar waveguide was “planar strip line”. A co-worker, Lou Napoli suggested the name coplanar waveguide. Thus with Lou’s suggestion, CPW invented CPW! “Classic” coplanar waveguide (CPW) is formed from a conductor separated from a pair of groundplanes, all on the same plane, atop a dielectric medium.

What is grounded coplanar waveguide (GCPW)?

A variant of coplanar waveguide is formed when a ground plane is provided on the opposite side of the dielectric, which is called finite ground-plane coplanar waveguide (FGCPW), or more simply, grounded coplanar waveguide (GCPW).

What is a 517 μm tall copper coplanar waveguide?

A 517 μm tall copper coplanar waveguide created using LIGA technique. Coplanar waveguide is a type of electrical planar transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals.
