“…These results are logical comparing with those of reference [10] for a rectangular patch antenna having the same parameters (patch surface and substrate thickness) using the moment method. Noting that, both rectangular and triangular microstrip antennas have generally the same behaviour and radiation characteristics [11], with some differences on the values of the resonant frequency, this must be improved in the following section.…”

Abstract-Using a new combined approach, the effect of the uniaxial anisotropic dielectrics on the resonant frequency and radiation field of an equitriangular patch antenna is presented in this paper. The problem is analysed in the spectral domain using the moment method and an electric field integral equation combined with a mathematical approach. However, the dyadic Green's functions corresponding to the proposed structure are separately developed and the Fourier transform of the basis current components are calculated mathematically using "the reference element" method. Numerical results show that the change in the resonant frequency and the radiation patterns of the antenna is due primarily to a small disturbance of the substrate's nature. Then the effect of the uniaxial anisotropic materials is a significant parameter and most essential on the microstrip antenna characterization.

A new method based on the adaptive neuro-fuzzy inference system (ANFIS) for calculating the resonant frequency of the equilateral triangular microstrip patch antenna is presented. The ANFIS has the advantages of the expert knowledge of the fuzzy inference system and the learning capability of neural networks. A hybrid-learning algorithm, which combines the least-square method and the backpropagation algorithm, is used to identify the parameters of ANFIS. The results of the new method show better agreement with the experimental results, as compared to the results of previous methods available in the literature.

“…Among all triangular geometry only equilateral shape has been widely investigated by the researchers [1][2][3][4][5][6][7][8][9][10][11][12]. Other geometry like right angle isosceles triangular patch antenna (RAITPA) is least investigated till now.…”

a fast and accurate CAD model based on cavity model analysis has been proposed to predict the input impedance and bandwidth of a tunable right angle isosceles triangular patch antenna (RAITPA).The effect of suspended substrate on the input impedance and bandwidth has been thoroughly investigated. The accuracy of the present model is computed against the HFSS simulated results. The present model shows very good agreement with the simulated results. For designing the MIC on semiconductor materials with ε r ≥ 10, this model will be widely applicable.
