A new type of broadband circularly polarized leaky-wave antenna (LWA) with high-gain based on a corrugated substrate integrated waveguide (CSIW) structure is proposed and investigated. The CSIW that employs open-circuit stubs to replace metallic vias has the advantages low-cost easy fabrication as compared conventional waveguides. Each unit-cell LWA consists two quarter-wavelength microstrip lines half-mode cell three stubs. Two M-shaped slots etched enables generation (CP) radiation. full...
A broadband metasurface with phase and amplitude modulation is proposed in this paper. The unit comprises four distinct quarter-round patches variable resistors that effectively reflect absorb electromagnetic waves through the manipulation of resistor values. Amplitude control are achieved by adjusting resistance values these resistors. When utilized as an absorber, absorption rate exceeds 90%. As a 1-bit element, it achieves 180° response within ultra-wideband operating range 14.3-28.7 GHz....
This paper presents a reflectarray (RA) unit with gain filtering characteristic based on 1-bit magnetoelectric (ME) dipole. The reflection element comprises pair of ME dipole, ground plane and feeding arm.

A double layer printed compact UWB monopole antenna with modified patches is proposed in this paper. Slots and shorted strip line are used to increase the bandwidth of antenna. At first, order bandwidth, two U-shaped slots a narrow slit etched on top patch, added between bottom patch ground. Therefore, above designs can make characteristic wideband that simulated S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> (-10 dB) 2.5 GHz...
Power dividers and phase shifters play important roles in microwave systems such as base stations, radars other mobile devices. With the development of various wireless communication systems, working bandwidth for many terminal devices will be more multi-band or broadband. The RF circuits power shifters, therefore, should designed broadband to meet systems. This cause some problems design shifters.In circular polarization antenna application a feeding network can provide 90 deg realize good...
A novel large phase-delay transmission line based on dual printed circuit boards (PCBs) for substrate integrated waveguide (SIW) is proposed. Rectangular slots and metallic vias are used to enhance the phase delay feature. The simulated results show difference of proposed phase-delayed SIW with PCBs -577° at concerned frequency 12 GHz. characteristic design has been analyzed through simulations compared both micro-strip single-layer which using same definite physical length. that performance...
Power divider and attenuator as key electrical devices play an important role in radio frequency testing for measuring circuits or protecting instruments. However, most of the power dividers attenuators currently used are discrete, combination these will affect test accuracy due to impedance mismatch. In this paper, we propose a new based on combined Wilkinson structure, which can realize multidirection distribution attenuation at different positions. The circuit structure is mainly composed...
We propose a co-coaxial coupling structure to realize power transmission in double-layer or multilayer rectangular SIWs at any direction. The proposed is formed coaxial by adding metallic via and etching circular ring slot on the section of each SIW layer. shared can support TEM mode for between different layers. take as an example simulate its S-parameters from top layer bottom when wave propagation directions (△θ) are designed 0° (parallel), 90° 135° with...
