“…So RF-MEMS actuators with novel SIW technology are good candidates to be replaced with solid phase shifters and microstrips, respectively. They provide advantages of fast actuation and integrated fabrication coupled with attractive options for low-cost high-frequency systems [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Reconfigurable RF-MEMS antennas were first introduced in 1998 by E. Brown and have been studied by several research groups with emphasizing in reconfigurability of aperture and microstrip antennas [12][13][14].…”

Abstract-In this article, a novel compact reconfigurable antenna based on substrate integrated waveguide (SIW) technology is introduced. The geometry of the proposed antennas is symmetric with respect to the horizontal center line. The electrical shape of the antenna is composed of double H-plane SIW based horn antennas and radio frequency micro electro mechanical system (RF-MEMS) actuators. The RF-MEMS actuators are integrated in the planar structure of the antenna for reconfiguring the radiation pattern by adding nulls to the pattern. The proper activation/deactivation of the switches alters the modes distributed in the structure and changes the radiation pattern. When different combinations of switches are on or off, the radiation patterns have 2, 4, 6, 8, . . . nulls with nearly similar operating frequencies. The attained peak gain of the proposed antenna is higher than 5 dB at any point on the far field radiation pattern except at the null positions. The design procedure and closed form formulation are provided for analytical determination of the antenna parameters. Moreover, the designed antenna with an overall dimensions of only 63.6 × 50 mm 2 is fabricated and excited through standard SMA connector and compared with the simulated results. The measured results show that the antenna can clearly alters its beams using the switching components. The proposed antenna retains advantages of low cost, low cross-polarized radiation, and easy integration of configuration.

“…In fact, a considerable number of SIW based devices designed using commercial codes, like HFSS (Ansys HFSS), have been presented over the years. Filters [2-4, 23, 24], power dividers [5][6][7], antennas [8,9,25] and other devices have been successfully designed and realized. However, more effective analysis methods can be devised implementing techniques that, even less general than the one used in commercial codes, are more efficient in terms of both CPU time and occupied memory.…”

Abstract-In this paper, a full-wave analysis technique of lossy substrate integrated waveguides, based on the dyadic Green's function of the parallel plate waveguide, is presented. The field inside the waveguide is expressed in terms of cylindrical vector wave-functions and the finite conductivity of the top and of the bottom plates, and of the metallic vias are taken into account. Losses into the dielectric substrate are also included. Coaxial ports are considered as sources and self and mutual admittances are evaluated. Cases of practical structure taken from literature are presented showing a very good agreement with the most used commercial software.

“…Especially the massively coupled multiple vias behave like efficient radiators, thereby introducing significant electromagnetic interference (EMI), crosstalk and radiation loss [1]. Because of the limited number of ports of network analyzer, the hardware measurement and calibration of the complete network is difficult [2].…”

Abstract-A 3D full-wave approach, based on the Foldy-Lax multiple scattering equations, is successfully extended to model massivelycoupled multiple vias using differential signaling and shared antipad in high speed vertical interconnects. For the first time, this method has been used and tested on via-pair with shared antipad in multilayered structure. The magnetic frill current source on the port is calculated by using the finite difference method. Banded matrix iterative method is applied to accelerate the finite difference calculation. Numerical example of 15 signal via-pairs and 20 ground shielding vias in 6-layer board demonstrates that this approach is able to model the via-pair with shared antipad and to include all the coupling effects among multiple vias. The electrical performances of different signal driving schemes are provided and discussed. The coupling crosstalk on various via-pairs is compared. The improvement of signal integrity is shown by using differential signaling and shared antipad for via-pair in multilayered structure. The results are compared with HFSS and SIwave in accuracy and CPU. The CPU using Foldy-Lax approach is three orders of magnitude faster than using HFSS, and two orders of magnitude faster than using SIwave. The accuracy of Foldy-Lax is within 2% difference from HFSS up to 20 GHz, and outperforms SIwave in accuracy.
