“…From the Table 1 it can be observed that the positive uniaxial anisotropy slightly increases the resonant frequency, while the negative uniaxial anisotropy slightly decreases both resonant frequency. 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.…”

“…The results shown in Table 2 for the numerical data presented by [10] and [12] for a rectangular patch antenna with dimensions (1.9 × 2.29) cm 2 and substrate thickness of d = 0.159 cm are compared with our computed results for an equitriangular patch having the same surface of the rectangular patch, so with side length a = 3.17 cm. The obtained results show that when the permittivity along the optical axis ε z is changed and ε x remains constant the resonant frequency changes drastically, on the other hand, a slight shift is observed in the resonant frequency when the permittivity ε x is changed and ε z remains constant, these behaviors agree very well with those obtained by [12], with a light increase in the values compared to the rectangular patch antenna.…”

“…For the resonant patch, entire domain expansion currents lead to fast convergence and can be related to a cavity model type of interpretation [8,9]. The currents can be defined using a sinusoid basis functions defined on the whole domain, without the edge condition, these currents associated with the complete orthogonal modes of the magnetic cavity.…”

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.

“…In this paper we extend our study [2,3] to the case of a superstrate-loaded resistive rectangular microstrip structure, where the superstrate layer loaded on the microstrip structure is often used to protect printed circuit antennas from environmental hazards, or may be naturally formed during flight or severe weather conditions [1,4].…”

The scattering radar cross section (RCS) of a superstrate loaded resistive rectangular microstrip patch which is printed on isotropic or uniaxial anisotropic substrate are investigated, where an accurate design based on the moment method technique in the spectral domain is developed. Entire domain sinusoid basis functions without edge condition and roof top sub-domain basis functions are introduced to expand the unknown current on the metal patches. The integral equation includes a superstrate resistive boundary condition on the surface of the patch and the effects of anisotropic substrate are developed. The necessary terms for representing the surface resistance on the patch were derived and were included in the equation in the form of a resistance matrix. Comparative study between our results and those available in the literature is done and showed a very good agreement.

This paper presents a simple approach for accurate determination of the resonant frequency of an elliptical microstrip patch printed on isotropic or anisotropic substrate materials. In this approach, some modifications are made to account for fringe fields, dispersion effects, and losses by calculating effective dimensions, effective permittivity of anisotropy in the layer, and effective loss tangent, respectively. The theoretical resonant frequency results are in very good agreement with the experimental results reported elsewhere. Numerical results show that the change in the resonant frequency 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.
