A Post-Wall Waveguide Slot Array with a Three-Way Power Divider on a Single-Layer Dielectric Substrate

A Wilkinson power divider with improved bandpass filtering and high isolation performance is proposed. These characteristics are achieved by replacing the quarter-wavelength transmission line in the conventional coupled line Wilkinson power divider with quarter-wavelength side-coupled ring (QSCR). Additional features such as DC blocking between arbitrary two ports, single-layer via-less structure for low-cost fabrication and convenient integration (as only one isolation resistor required) are highlighted. A 2-GHz Wilkinson microstrip power divider with a fractional bandwidth of 4% has been fabricated and experimentally characterized. The consistency between simulated and measured results validates the effectiveness of our proposed design.

Circuit Technology

A novel small-size filtering power divider (PD) featured four-function integration is proposed. These four integrated functions are high-selectivity filtering, inherent DC block, high all-frequency isolation, and high-power applications. Using single-layer planar circuit technology, this proposed PD can be implemented easily. The measured results of a prototype show that it can operate at 2 GHz with a −10 dB matching bandwidth of 6% and all-frequency −15 dB isolation.

Simple Matrix

A new, rigorous, field-based, seminumerical analysis method is presented to obtain the reflection and transmission coefficients of 2D planar periodic structures with arbitrarily shaped metallization patterns for both normal and oblique incidence conditions. It is useful for the analysis, design, and optimization of many single-layer and multilayer planar structures, such as frequency-selective surfaces (FSSs), artificial magnetic conductor (AMC) surfaces, electromagnetic bandgap (EBG) structures, some metamaterials and high-impedance surfaces. In this coupled-field expansion method (CFEM), thex- andy-components of the vector magnetic potential in each homogeneous region in a unit cell are expanded in terms of Bloch-Floquet modes and the solution to the coupled-field problem is formulated. The unique, analytical formulation presented here leads to a linear system with reasonably simple matrix elements. By cascading the matrices representing each interface, multilayer periodic structures are analyzed in a very flexible way. Being field based, CFEM does not require substrate Green's functions to analyze surfaces printed on dielectric substrates. The method was validated by analyzing one single-layer periodic surface (a printed AMC on a dielectric substrate) and one multilayer periodic surface (a circular polarizer) and comparing CFEM results with HFSS results.
