At the present time, radar in a single shape or one other is probably going to show up in every single place: on the street, on the waterfront, in an underground motor-road. by means of some distance the widest use of radar is made by way of the army and scientists. In all of those fields millions upon millions of radar units are at paintings. a few of them are sufficiently small to be outfitted into spectacles, others weigh 1000s of lots.

Simons Copyright  2001 by John Wiley & Sons, Inc. 1 INTRODUCTION The coplanar waveguide (CPW) proposed by C. P. Wen in 1969 consisted of a dielectric substrate with conductors on the top surface [1]. The conductors formed a center strip separated by a narrow gap from two ground planes on either side. The dimensions of the center strip, the gap, the thickness and permittivity of the dielectric substrate determined the effective dielectric constant ( ), characteristic impedance (Z ) and the attenuation ( ) of the line.
