The results presented in this paper show that by employing a combination of metasurface and substrate integrated waveguide (SIW) technologies, we can realize compact low-profile antenna overcomes the drawbacks narrow-bandwidth low-radiation properties encountered terahertz antennas on-chip (AoC). In addition, an effective RF cross-shaped feed structure is used to excite from its underside coupl...

In this paper, a novel perturbation approach for implementing the independently reconfigurable dual-mode dual-band substrate integrated waveguide (SIW) filter is proposed. Dual-frequency manipulation is achieved by adding perturbation via-holes (the first variable) and changing the lengths of the interference slot (the second variable) in each cavity. The independent control of the upper passba...

A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...

in this article, we suggested a novel design of polarization splitter based on coupler waveguide on inp substrate at 1.55mm wavelength. photonic crystal structure is consisted of two dimensional (2d) air holes embedded in inp/ingaasp material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. the photonic band gap (pbg) of this structure is determined using t...

Since the achievable gain of transistors typically falls off as the frequency increases, an equalization filter with positive gain slope is necessary to compensate for the gain roll-off of broadband amplifiers. This paper proposed an novel equalizer structure and design a equalization filter by applying this novel structure and a modified SIW-PBG (Substrate Intergrated Waveguide-Photon BandGap)...

Microstrip lines (MSL) are widely used in microwave systems because of its low cost, light weight, and easy integration with other components. Substrate integrated waveguides (SIW), which inherit the advantages from traditional rectangular waveguides without their bulky configuration, aroused recently in low loss and high power planar applications. This chapter proposed the design and modeling ...

With the increasing demand for high-speed data, rapid deployments of 5G terrestrial heterogeneous wireless networks are expected worldwide in next decade. In such networks, sub-6 GHz macro-cells overlapped by mmWave small-cells being used to cater densely populated regions. As a result, several challenges arise with antenna design technologies at mobile terminal, access points, or backhaul/fron...
