Improved Model to Compute Resonant Frequency of Right Angle Isosceles Triangular Patch Antenna with and without Suspended Substrate

An improved CAD model based on cavity model analysis has been proposed to compute the resonance frequency of a right angle isosceles triangular patch antenna (45-45-90) with and without suspended substrate. The model is found to be valid for wide range of antenna parameters like patch side length, substrate thickness and dielectric constant. A standard electromagnetic simulator (HFSS) has been ...

Attraction Controls the Entropy of Fluctuations in Isosceles Triangular Networks

We study two-dimensional triangular-network models, which have degenerate ground states composed of straight or randomly-zigzagging stripes and thus sub-extensive residual entropy. We show that attraction is responsible for the inversion of the stable phase by changing the entropy of fluctuations around the ground-state configurations. By using a real-space shell-expansion method, we compute th...
