As one of the most populous countries in world, China is experiencing significant shifts dietary patterns actively implementing range interventions. </sec> <title>OBJECTIVE</title> This study seeks to provide comprehensive assessment burden explore their trends from 1990 2021. <title>METHODS</title> Data on sex- age- specific burdens...
An ultrawideband omnidirectional patch antenna with vertical polarization and low profile is proposed. It composes of a circular patch, eight short pins ground plane. Two propagation modes TM <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> xmlns:xlink="http://www.w3.org/1999/xlink">02</sub> are produced when the excited by 1-to-8 power divider, while other two additionally embedding ring slots in A slot then loaded to enhance impedance...
A dual-band vertical polarization omnidirectional antenna is proposed with the same three substrates in a low profile. The design configured four horizontal layers, wheel-shaped patch (Patch 1) an outer loop strip on upper of top printed circuit board (PCB) (Sub1), fan-shaped 2) mid PCB (Sub2), four-sector bottom (Sub3), and ground ring slot lower Sub3. layers are central coaxial probe from Sub3 to Patches 1 2, inner posts Patch Sub1, 1. Based new structure, five resonant modes passband one...
In this paper, a novel circularly polarized (CP) leaky-wave antenna with wide bandwidth is presented. The proposed has structure based on microstrip line loaded X-shaped slots. To generate waves, the feeding position of shifted from center X-slot to edge. Then straight feed can form phase difference between two arms without meandering line, increasing radiation efficiency. When 90degrees, radiate orthogonal field within required phases, thus synthesizing circular polarization. have no...
The Ultra-Wideband antenna can effectively improve the system performance, such as range resolution, anti-jamming performance and complex target recognition.It is very important to study UWB antenna.In this paper, discussed studied, influence of size miniaturization on bandwidth analyzed by method feeding shape antenna.The coplanar waveguide feed appropriate topology bandwidth.
