An approximate complex image green's function for a truncated dielectric substrate

Symposium on Antenna Technology and Applied Electromagnetics [ANTEM 1994], 1994

In MIC's and printed antennas the dielectric substrates always have finite extent. Rigorous analysis of the truncation effects requires the solution of an integral equation with MoM. This is usually numerically intense especially for 3-D structures. In this paper the truncation effects are incorporated directly in an approximate Green's function. The Characteristic Green's Function (CGF) technique is combined with the ...

  • An approximate complex image green's function for a truncated dielectric substrate

    In MIC's and printed antennas the dielectric substrates always have finite extent. Rigorous analysis of the truncation effects requires the solution of an integral equation with MoM. This is usually numerically intense especially for 3-D structures. In this paper the truncation effects are incorporated directly in an approximate Green's function. The Characteristic Green's Function (CGF) technique is combined with the complex images method to derive the Green's function. The derived Green's function exhibits excellent agreement with the available rigorous MoM solution of the problem.

  • Designing of Smart Antenna for improved directivity and gain at terahertz frequency range

    In the present scenario the challenge is to transmit the data at rate 10 gigabits per second for the terahertz frequency regime. One prominent technique that can proffer solution for the efficient transmission at this frequency wideband is Smart Antenna. This research work proposed and examined smart antennas also known as adaptive array antennas at terahertz frequency range. The prototype antenna is suitably operating in the range of 300 GHz to 3 THz for wireless local area network applications that uses high-frequency radio waves. The antenna has been put together on a Rogers RT Duroid dielectric substrate of Svensson/Djordjevic loss type with dielectric permittivity of εr= 2.33, loss factor/tangent (tan δ) of 1.2 * 10-3, relative permeability (μr) = 1 and the thickness of h = 0.80 mm. Rogers RT Duroid dielectric substrate has been taken as our substrate due to the low dielectric loss which make it suitable for high-frequency laminate over the FR-4 substrate. The antenna receives input power and radiated power at 15.55 Watts in a specific direction, focusing the desired signals from where they come forth allowing for increased radiation efficiency of 100% and mitigate interfering signals from unwanted sources. The antenna has a peak directivity of 17.6 dB, this made it possible for the maximum power transfer. The simulated results are shown in Fig. 1 to Fig. 3. The sum of the far fields E radiated from the array is equation where Eiis the far field of the ith antenna given as: equation.

  • Efficient Analysis of Substrate Integrated Waveguide Devices Using Hybrid Mode Matching Between Cylindrical and Guided Modes

    In this paper, a new method to efficiently analyze substrate integrated waveguide (SIW) based devices with multiple accessing ports is presented. The problem is considered as a 2-D electromagnetic problem assuming no field variation normal to the dielectric substrate. The incident and scattered fields from each circular cylinder are expanded with cylindrical modes, and the fields in the waveguide ports are expanded using progressive and regressive modal summations. The addition theorems of Bessel and Hankel functions are used to analyze the full-wave behavior of the SIW device. In order to extract the circuital parameters, the hybrid mode-matching between guided and cylindrical modes is done by projecting continuity equations in a circular boundary containing the whole SIW structure over the inner modes of each region. Applying this new technique, it is possible to analyze multiple port devices by solving a set of integrals that can be easily approached analytically or by using the inverse fast Fourier transform, avoiding the use of non efficient numerical methods. It is shown that the new method runs faster than commercial software packages and other techniques recently published.

  • Compressed Dipoles Resonating at Higher Order Modes With Enhanced Directivity

    A compressed dipole operating at higher order modes is proposed and investigated for the enhancement of boresight directivity. Compared with conventional dipoles in free space, the length of the proposed dipole is compressed although the currents on the compressed dipole still sinusoidally distribute. The traces of calculated compressed dipole's directivity against compressibility show that the directivity of a compressed dipole operating at higher resonant modes is larger than conventional dipoles for the well selected compressibility. This paper shows that printing the dipole onto a piece of dielectric substrate can achieve the desired compressibility. The relationship between the compressibility and relative permittivity of the dielectric slab provides the guidance to realize the selected compressibility. As an example, a thin linear compressed dipole resonating at the third mode is designed, fabricated, and measured to validate the method. The measured broadside gain of the proposed compressed dipole reaches up to 4.6 dBi, 75% or 2.45 dBi higher than a conventional dipole.

  • Electromagnetic Analysis for Inhomogeneous Interconnect and Packaging Structures Based on Volume-Surface Integral Equations

    Electromagnetic analysis for interconnect and packaging structures usually relies on the solutions of surface integral equations (SIEs) in integral equation solvers. Though the SIEs are necessary for the conductors in the structures, one has to assume a homogeneity of material for each layer of a substrate if SIEs are used for the substrate. When the inhomogeneity of materials in the substrate has to be taken into account, then volume integral equations (VIEs) are indispensable. In this paper, we consider the inhomogeneous materials of substrate and replace the SIEs with the VIEs to form volume-surface integral equations (VSIEs) for the entire structures. Also, the use of VIEs could alleviate low-frequency effects, remove the need of selecting a basis function for magnetic current, and facilitate geometric discretization in some scenarios. The VSIEs are solved with the method of moments by using the Rao-Wilton-Glisson basis function to represent the surface current on the conductors and Schaubert-Wilton-Glisson basis function to expand the volume current inside the substrate. To avoid the inconvenience of charge density in the traditional implementation of the VIEs, we suggest that the dyadic Green's function be kept in its original form without moving the gradient operator onto the basis and testing functions. Numerical examples are presented to demonstrate the effectiveness of the approach.
