In this paper, a wideband 3 dB hybrid 180° rat-race coupler is introduced in the printed ridge
gap waveguide technology. It has simultaneous wide matching and isolation bandwidth with …

In this article, a tri‐band 180‐degree directional coupler with spurious suppression is
proposed. This coupler is realized using the extended π‐shaped Microstrip operating at 3 …

Разработан компактный трехшлейфный мост с использованием микрополосковых
ячеек, установленных вместо традиционных четвертьволновых отрезков. С помощью …

Данная книга посвящена исследованиям, связанным с процессом миниатюризации
делителей мощности. В работе приведено сравнительное описание компактных …

Working at millimeter waves (MMW) has gained massive attention for wireless
communications and imaging systems. For imaging systems, MMW can be used for security …

Taking CSRR (Complementary split ring resonator) and OCSRR (Open complementary split
ring resonator) for inspiration, this thesis attempts to design a resonator for low frequency …

This paper presents the design for a rat-race coupler and design equations for THz band
applications is presented. The S-parameter of proposed structure is calculated. The design …
