“…The expression mentioned in ref. gives a good approximation between equivalent SIW width “ A e ” and equivalent dielectric filled rectangular waveguide width “ A r ” as a function of via spacing and diameter:

A_{normale} = A_{normalr} - 1.08 \frac{D^{2}}{P} + 0.1 \frac{D^{2}}{A_{normalr}}

High‐performance, wideband three‐stage power splitters based on substrate integrated waveguide (SIW) are presented. Broadband‐tapered microstrip transitions are used for feeding the SIW structures, which provide 7.5 GHz bandwidth from 21.5 to 29 GHz with return loss below −20 dB. In addition, various T junctions are tuned, not only to provide broadband performance up to mm‐wave frequencies but also offer low‐phase and amplitude imbalance when cascaded in multistage 1 × 8 splitters. 1 × 4 and 1 × 2‐T junctions are adjusted through parametric analysis to provide wide bandwidth of 3.5 GHz at 24.5 GHz and −15 dB reflection coefficient. The optimal microstrip transitions and T junctions are used to design a broadband, eight‐way power splitter with 15 dB return loss from 23.0 to 26.4 GHz and phase and amplitude imbalance of ±2.5° and ±0.8° dB, respectively. Furthermore, optimum positions of all inductive posts in terms of guided wavelength are also provided for assisting the direct design of mm‐wave, high‐performance power splitters.

“…Unfortunately, waveguide‐based devices are difficult to integrate with planar circuits which are commonly used now‐a‐days. However, during the last decade, substrate integrated waveguides (SIW) have emerged as a low‐cost planar alternative for conventional waveguides and can be easily integrated with planar circuits …”

In this article, empirical design formulae for a unit cell of series‐fed substrate integrated waveguide power divider for a wide range of power division ratio from 1:1 to 1:40 are presented. These formulae are determined through extensive simulations carried out in Ansys HFSS. The physical dimensions of the power divider for any given power division ratio can be directly determined through the design formulae presented in the article. A simple design procedure is discussed and verified with the help of experimental and simulation results. For experimental verification, a power divider is designed to operate in X band, and its prototype is developed on RT Duroid 5880, the measured results for this power divider are in close agreement with simulated as well as predicted results. Also, for validating the design procedure over a wide range of frequencies, many power dividers are designed with different power division ratios, different operating frequencies and different cut‐off frequencies of TE10 mode. The cut‐off frequency (fc) of TE10 mode is varied from 15 to 25 GHz, and the operating frequency is adjusted in between 1.2fc and 1.8fc. That is, 18–40 GHz, which is suitable for many microwave and millimeter wave applications. The obtained results are very close to the desired power division ratios.

“…One approach to the problem is to use planer antennas, which are light weight, planar, compact, and inexpensive. Recently, there has been growing interest in SIW-based antennas [5][6][7]. SIW structure preserves the advantages of metallic waveguides, namely high Q-factor (low loss) and high powerhandling capability with self-consistent electromagnetic shielding.…”

“…Because of its advanced features related to loss and narrow-beam waveguide slot array antennas are very attractive for satellites communication applications. The SIW slot antennas in the literature employ planar SIW structures [6,7,[10][11][12]. Both longitudinal slot [10] and transverse slot [13] on the broad wall of an SIW can be used as radiating element of a linearly polarized SIW slot array.…”

Abstract-This paper presents the design and fabrication of an antenna based on Substrate Integrated Waveguide (SIW) for intersatellite crosslinks in C-band. The entire antenna consists of two elements of SIW slots array that is fed by a hybrid 3 dB directional coupler. The entire SIW slots array antenna is circularly polarized (CP), and each element has four longitudinal slots. The element's effective field matching is realized with a microstrip to SIW transition. The antenna design has been evaluated with its return loss, gain plot, and radiation pattern characteristics to validate the fabricated antenna. The fabricated prototype antenna radiates a left-handed circularly polarized (LHCP) electromagnetic wave with the peak gain of 5 dB and offers approximately 2% AR bandwidth around 5 GHz.
