A new design of wideband branch-line coupler (BLC) using T-shape with open stub
microstrip line is proposed. The branch line coupler is integrated with low and high …

A wideband 90° microstrip hybrid coupler with a bandwidth of 84.3% is proposed. The
hybrid coupler consists of a two-section coupled-line power divider and a 90° phase shifter …

This paper presents a novel wide-band filtering three-port coupler with inherent DC-blocking
function, which is simply comprised of a power divider with wideband filtering function and a …

This article presents a transmit/receive switch that utilizes a broadband microstripline hybrid
coupler. The proposed switch is suitable for application in both 3T and 7T magnetic …

The paper presents a new design of a compact branch-line coupler (BLC) operating at 3.5
GHz, that is suitable for 5G applications. In order to miniaturize the proposed coupler, two …

A suitable method is introduced to improve the isolation of slot‐coupled directional couplers.
The proposed coupler consists of two trapezoidal‐shaped patches that are coupled through …

This paper presents a wide-band quadrature modulator's design, simulation, and
performance evaluation using a 90°-hybrid coupler. Three different center frequencies of 3.0 …

ABSTRACT A compact ultra‐wideband three‐port quadrature hybrid based on a coupled‐
line 90° phase shifter and a Wilkinson power divider is proposed. The circuit configuration …
