What is coplanar wave?
Conventional coplanar waveguide (CPW) consists of a single conducting track printed onto a dielectric substrate, together with a pair of return conductors, one to either side of the track. The electromagnetic wave carried by a coplanar waveguide exists partly in the dielectric substrate, and partly in the air above it.
What is CPW antenna?
The CPW is the feeding which side-plane conductor is ground and centre strip carries the signal. The advantage of CPW fed slot antenna is its wide band characteristics. Hence CPW fed slot antenna is most effective and promising antenna for wideband wireless application.
Which is the advantage of CPW fed microstrip antenna?
There are several feeding technique like coaxial probe fed, microstrip line fed, edge fed, inset fed, CPW fed. The CPW is the feeding which side-plane conductor is ground and centre strip carries the signal. The advantage of CPW fed slot antenna is its wide band characteristics.
Which is easier to fabricate microstrip or GCPW?
Obviously, microstrip has an “elegant simplicity” to it, which makes it easier to fabricate and even easier to model via computer than GCPW circuits.
Which is Lossier a microstrip or a CPW circuit?
CPW circuits can be lossier than comparable microstrip circuits, if you need a compact layout. In terms of circuit size, CPW is at a disadvantage versus a stripline of microstrip circuit, because it’s effective dielectric constant is lower (half of the fields are in air).
Are there any disadvantages to using microwaves with CPW?
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. One disadvantage is potentially lousy heat dissipation (this depends on the thickness of the dielectric and whether it makes contact to a heat sink).
