Fast and accurate model for circular microstrip antennas on suspended and composite
Nasimuddin, Karu Esselle, and A. K. Verma
Abstract—We present a fast and accurate closed-form model for interactive
computer-aided design and optimization of circular microstrip
antennas on suspended or composite substrates. The model facilitates the
computation of the resonance frequency,input impedance and bandwidth.
We compare the results obtained with the proposed model with those from
commercial software (2D-Ensemble and 3D-Microwave Studio),pr eviously
published experimental results and previously obtained theoretical
results using another full-wave method. The proposed model shows better
agreement with experimental results as compared to the commercial
two-dimensional and three-dimensional software. Although all theoretical
results show reasonable agreement among themselves,the proposed model
is at least one thousand times faster than full-wave software.
