		In the preferred embodiment, the microstrip and coplanar waveguide are made of 2 micrometer thick gold with a 10 nm thick titanium adhesion layer by electron-beam evaporation and lift-off etching processing.
		For the latter case, the 50-ohm coplanar waveguide is transformed to the 50-ohm microstrip line by direct connection of the central line of coplanar waveguide to microstrip line.
		Coplanar phase shifters made from conventional tunable materials are extremely lossy, and useless for phased array antennas at K and Ka bands.

	Defining a Coplanar Port
		It is similar to a differential port, but coplanar ports are applied to objects on slot layers (that is, where slots are used in the design).
		Coplanar ports should be used in situations where an electric field is likely to build up between two ports.
		Note Port numbers for coplanar ports are treated in the following manner: on the layout, you will continue to see the port numbers (instance names) that were assigned to each port when they were added to the layout.

		Thresholds were lower with the coplanar than with the non-coplanar reference surface.
		We investigated whether coplanar judgments worsened when the ratio cue was made ambiguous.
		Observers judged whether the test surface was closer or farther away than the extended surface of the reference (i.e., coplanar).

		A third coplanar waveguide electrode 82-3 has a shape symmetric to the first coplanar waveguide electrode 82-1, and separated apart from the second coplanar waveguide electrode 82-2 by a distance the same as the distance between the first and second coplanar waveguide electrodes 82-1 and 82-2.
		Similarly, a sixth coplanar waveguide electrode 82-6 has a shape symmetric to the third coplanar waveguide electrode 82-3 and separated apart from the fifth coplanar waveguide electrode 82-5 the same as the distance between the second and third coplanar waveguide electrodes 82-2 and 82-3.
		The second and the fifth coplanar waveguide electrodes are connected to the first and the third, and to the fourth and the sixth, coplanar waveguide electrodes respectively, through terminating resistors.

	Coplanar Waveguide- Microwave Encyclopedia - Microwaves101.com
		"Classic" coplanar waveguide (CPW) is formed from a conductor separated from a pair of groundplanes, all on the same plane, atop a dielectric medium.
		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).
		The advantages of coplanar waveguide are that active devices can be mounted on top of the circuit, like on microstrip.

		Any transmission line with three coplanar conductors, where the center conductor is fed 180 degrees out of phase with the two outer conductors, can be considered a coplanar waveguide line.
		Grounded Coplanar: The bottom of the substrate has a metal ground plane which is electrically connected to the two outer conductors.
		Floating Coplanar: Use push-pull ports because the metal on the bottom of the substrate is not connected to the two outer conductors.

	2000 WL 1123260
		Regalo also contends that the legs of the accused device do not pivot about their pivot connection into and out of the plane defined by each hinged member of the central hub to a compact non-coplanar configuration, but, rather, the leg pairs remain in the same plane as the hinged members.
		Thus, Regalo's concern that the term "radially" has no meaning unless the "coplanar" and "noncoplanar" language of Claim 1 is interpreted to include the legs with respect to the hub is unfounded.
		Therefore, this Court concludes that Regalo's attempt to read into the claim language the requirement that the "coplanar" and "non-coplanar" language references the position of the legs with respect to the hub is unsupported by the patent itself.

		If a coplanar point is assigned to the wrong facet, qh_check_maxout may reach a local maximum instead of locating all coplanar facets.

		This change has the effect of doubling the perceived coplanar signal strength: for example what was 100 ppm (parts per million) signal will now become 200 ppm.
		If the secondary from the earth is S from the coplanar Tx, then the response from the vertical coaxial Tx will be S/2.
		However, by geophysical theory, the absolute response of a layered halfspace to a horizontal coplanar coil is only twice that of a vertical coaxial coil transmitting the same field.

	Finite Ground Coplanar (FGC) Waveguide Evaluated for Communication Circuits
		Traditionally, radiofrequency and wireless circuits have employed a microstrip or coplanar waveguide to interconnect the various electrical elements that comprise a circuit.
		Although a coplanar waveguide (CPW) is widely viewed as better than a microstrip for most applications, it too has problems.
		All these results indicate that the FGC waveguide is a better transmission line than the coplanar waveguide and the microstrip for radiofrequency and wireless circuits.

		The clear positive correlations between concentrations of total PCBs and each of the three coplanar PCBs obtained in all mammals analysed suggest that the sources of coplanar PCB contamination to the environment are mainly commercial PCB preparations.
		Comparison of the composition of three toxic coplanar PCBs in commercial PCB mixtur es and in the various animals indicates the relative metabolisability of these congeners as follows: 3.3',4.4',-T4CB>3.3',4.4',5-P5CB>3.3',4.4',5.5'-H6CB.

	Characteristic impedance of coplanar strips (differential pair without ground)
		The Coplanar Strips model does not appear directly in the Si6000b, however there is a very simple adjustment you can make to one of the standard structures in the Si6000b to enable you to predict the finished impedance.
		Simply select the "Differential surface coplanar waveguide" (the one without a lower ground plane) and set the "D" dimension so it is 20 x the "S" dimension.
		This way the adjacent coplanar grounds will be far enough away to have negligible influence.

		The Z0 of a coplanar waveguide transmission line is determined by the distributed inductance and the distributed capacitance from the strip to the adjacent groundplane (through both the dielectric and air gap in the vicinity of the slots).
		Coplanar waveguide can be used to mount components in series and shunt without drilling and plated through holes.
		The circuit is built on a coplanar line 0.050” wide with 0.010” slots, cut using a jeweler’s saw at an angle with a brass strip as a guide.

		All these triangles are coplanar however, and the face still remains rectangular at the edges.
		This isn't for visual LOD, this is simply to try and remove unnecessary triangles from within a coplanar face and the face remains exactly the same shape.

	Coplanar - Wikipedia, the free encyclopedia
		A set of points is said to be coplanar if and only if they lie on the same geometric plane.
		Other points can be shown to be coplanar by determining that the scalar product of a vector that is normal to the plane and a vector from any point on the plane to the point being tested is 0.

		The definition in our Geometry book for intersecting lines states that two intersecting lines must be coplanar, but we can't understand why they couldn't lie in more than one plane and still intersect one another.
		Since two points on each line are in that plane, both entire lines must lie in that plane.
		Two lines that are not coplanar can be pictured as the center line of a road and the center line of another road that passes above the first on a bridge.
