Parametric Study and Temperature Sensitivity of Microstrip Antennas Using an Improved Linear Transmission Line Model

Sarath Babu and Girish Kumar, Senior Member, IEEE

Page 221.

Abstract:

An improved linear transmission line (LTL) model has been developed after incorporating several modifications in the reported linear transmission line model for analyzing arbitrarily shaped microstrip antennas (MSA's), which should be symmetrical with respect to the feed axis. Simulations have been carried out for rectangular, circular, and equilateral triangular MSA's and the results are in good agreement with reported results. A parametric study for these MSA's has also been performed. A study of the temperature sensitivity for rectangular MSA's for different types of substrates has been carried out. An MSA utilizing a substrate with a lower dielectric constant and thermal coefficient is less sensitive to temperature variations.
