A new CAD formulation is proposed to estimate accurate resonant frequency of rectangular microstrip patches having variable aspect ratio. The computed results are verified with several experiments. Compared to earlier ones, the proposed formula shows much closer approximations when compared with the measurements. © 2005 IEEE.

Microstrip radiating structures: Theoretical and experimental investigations executed in recent years at the University of Calcutta

An improved CAD formulation is proposed to determine accurate input impedance of rectangular microstrip patches with variable aspect ratio. This paper demonstrate the effect of aspect ratio of rectangular microstrip patch on its input impedance. The computed results have been verified with our own experiments and simulated data showing very close agreement amongst them. ©2007 IEEE.

CAD of mechanically tunable rectangular microstrip patch with variable aspect ratio

An improved analytical model is presented for calculating the resonant frequency of circular microstrip antennas with and without air gaps. Unlike the previous models, the present one is widely applicable to all patch diameters - from very large to very small compared to the height of the dielectric medium below the patch and also to the substrates covering the entire range of dielectric constants. The computed results for different antenna dimensions and modes of resonance are compared with the experimental values.
