M. Kara, EFFECTIVE PERMITTIVITY OF RECTANGULAR MICROSTRIP ANTENNA ELEMENTS WITH VARIOUS THICKNESSES OF SUBSTRATES, Microwave and optical technology letters, 10(4), 1995, pp. 244-247
A new expression has been developed for calculating the effective perm
ittivity of rectangular microstrip antenna elements with various thick
nesses of substrates. This technique is original, simple, and easily a
daptable to a wide variety of dielectric materials, scalable over wide
frequency ranges, and included in a CAD system. The results obtained
from this technique confirm those calculated form formulas reported el
sewhere. (C) 1995 John Wiley & Sons, Inc.
