We present a rigorous theoretical framework for designing full-space spatial power dividers using metagratings. In our study, the current restrictions of dividing platforms such as reflection-only performance, operating at normal incidence, and small reflection/refraction angles have been totally relaxed. A modal expansion analysis based on Floquet-Bloch (FB) theorem is established so that disc...

Abstract—A folded printed quadrifilar helical antenna (FPQHA) with an integrated and compact feeding network is proposed. The axial length of the proposed antenna is miniaturized of about 54.7% than the conventional PQHA by folding the helix arms into several elements. A T-junction power divider combining with two Wilkinson power dividers is utilized to feed the antenna. A fabricated prototype ...

Multiplexers and power combiners/dividers are crucial in many applications of electromagnetic waves including microwave terahertz communication. Full-duplex communication requires the separation transmitted received signals; thus, non-reciprocal multiplexers very essential. In this work, we present numerically study a design concept for such circuits from topological cavities. First, quad-port ...

A unequal Wilkinson power divider based on asymmetrical coupled line section is presented in this paper. The proposed unequal Wilkinson power divider topology uses asymmetrical coupled-line section and two transmission-line transformers. For simplification, a section asymmetrical coupled line is applied to obtain front compact matching structure. For generalization, three ports terminated imped...

This paper presents a monolithically integrated broadband lumped-element Wilkinson power divider centered at 20 GHz, which was designed and fabricated to uniformly distribute power to arrays of Josephson junctions (JJs) for superconducting voltage standards. This solution achieves a fourfold decrease in chip area, and a twofold increase in bandwidth (BW) when compared to the previous narrowband...

In this paper, new single/double-layer N-way Wilkinson power dividers (WPDs) were designed by using slow-wave structures such as narrow-slit-loaded and meandered transmission lines. For size reduction, the slit-loaded lines used instead of quarter-wavelength a conventional WPD. Based on proposed approaches, two-, four-, eight-way designed, simulated, fabricated. The fabricated 2-, 4-, 8-way cir...

1. Introduction Microstrip structures are very popular choices both for circuits and antennas. Wilkinson power dividers in microstrip form are indispensable components for printed antenna array feeding networks. In principle, low loss specialized microwave sub-strates are used for best results. However, since substrate cost is the dominant factor for microstrip passive circuits [1], there is a ...

This paper presents analysis and design of a dual band Wilkinson power divider for wireless applications. The design is accomplished by transforming the lengths and impedances of the quarter wavelength sections of the conventional Wilkinson power divider into dual band T-shaped sections. Simple design equations for the basic geometry are given. The designed dual band Wilkinson power divider str...
