Based on the concept of slow wave propagation, a dual-layer electromagnetic band gap (EBG) mushroom structure is used to reduce the area of a patch multi-antenna sub-system. While the inner layer aids in the antenna miniaturization, the more compact upper layer helps in further reduction of the mutual coupling between the miniaturized patch antennas which is otherwise not possible for a single-layer EBG. Simulation is also performed for the mutual coupling and radiation characteristics of the multi-antenna structure for different inter-element separations which are experimentally verified.
基于慢波传播的概念,采用双层电磁带隙蘑菇结构来减小贴片多天线子系统的面积。虽然内层有助于天线小型化,但更紧凑的上层有助于进一步减少小型化贴片天线之间的相互耦合,这对于单层EBG来说是不可能的。对不同单元间距下多天线结构的相互耦合和辐射特性进行了仿真,并进行了实验验证。

In this work we introduce a novel near-field focusing plate able to provide sub-wavelength focusing in both directions, parallel to the plate, as well as for both polarizations of the illuminating plane wave at microwave frequencies. Two similar designs are proposed: the first one is made of a thick metallic plate, whereas the second one is made of a thin copper plate fabricated on top of a Rogers 5880 dielectric substrate. The focusing behavior of these structures is analyzed with Ansys HFSS and CST Microwave Studio full-wave simulators.

In this paper, a new wireless sensing mechanism is proposed based on the integration of a cavity resonator and a slot antenna. A compact structure can be achieved since this integration eliminates additional volume of the antenna and transition structure between the resonator and antenna. A resonator/antenna is demonstrated to verify the proposed technique. The resonator/antenna size is 14 by 13 by 3 mm. The resonant frequency of the resonator, i.e. 10.13 GHz, can be wirelessly detected at distances up to 55 mm. This approach can be useful in high-temperature wireless sensing applications where only passive sensors can survive.
本文提出了一种基于空腔谐振器和缝隙天线集成的新型无线传感机构。由于这种集成消除了天线的额外体积以及谐振器和天线之间的过渡结构,因此可以实现紧凑的结构。一个谐振器/天线演示验证了所提出的技术。谐振器/天线尺寸为14 × 13 × 3毫米。谐振器的谐振频率,即10.13 GHz,可以在55毫米的距离内进行无线检测。这种方法在只有无源传感器才能生存的高温无线传感应用中非常有用。

Fast geometric parameter sweep of FEM models via a nonlinear BT-POD model reduction 基于非线性BT-POD模型约简的有限元模型几何参数快速扫描
Pub Date : 2011-07-03 DOI: 10.1109/APS.2011.5997024
Wei Wang, M. Vouvakis
A finite element method (FEM) model-order reduction (MOR) methodology for the fast parametric sweep of geometrical features is presented. The proposed method first linearizes the otherwise non-linear FEM matrix dependence with respect to the geometry variation, and then uses a uniformly sampled balanced truncation proper orthogonal decomposition (BT-POD) reduction algorithm to expediently sweep over the parametric geometry space. The approach avoids slow re-meshing and full matrix reassembly by using mesh morphing approaches. Moreover, BT-POD is known to provide close to optimal size reduced problems using only a small number of samples, thus minimizing the the number of full-model solutions. Numerical results on two large-scale filter design examples are used to study the accuracy and efficiency of the proposed method.
提出了一种用于几何特征参数快速扫描的有限元模型降阶方法。该方法首先将几何变化对非线性有限元矩阵的依赖线性化,然后使用均匀采样平衡截断适当正交分解(BT-POD)约简算法方便地扫描参数几何空间。该方法通过使用网格变形方法避免了缓慢的重网格和全矩阵重组。此外,已知BT-POD仅使用少量样本就能提供接近最优的缩小尺寸问题,从而最大限度地减少了全模型解决方案的数量。通过两个大型滤波器设计算例,验证了该方法的精度和效率。

In this contribution we introduce an approach to improve the remote sensing techniques of vegetation masses by considering the detection and analysis of the Brillouin precursor in a signal propagated through two different dispersive vegetation media for the frequency band under 3.5GHz. We compare the results due to three different propagated pulses: rectangular, Gaussian and inverted double ramp pulse.

Sub-array design diagnostics for the development of large uniform arrays 大型均匀阵列开发的子阵列设计诊断
Pub Date : 2011-07-03 DOI: 10.1109/APS.2011.5996431
T. Brockett, Y. Rahmat-Samii
The use of sub-arrays has been a popular approach in the design of large array antennas. Using sub-arrays simplifies the array design by allowing the designer to concentrate on the smaller sub-array and repeating it throughout the rest of the array. Anomalous grating lobes have been shown to appear in large uniform arrays caused by systematic errors in the design of sub-array. Thus, it is important for the sub-array designer to be able to diagnose errors in the sub-array design before incorporating it into the larger array. This paper will categorize and demonstrate specific sub-array pattern distortions that can cause grating lobes to appear in uniform arrays. In addition, a design example will present how recognition of the aforementioned distortions can be used to diagnose and prevent the appearance of grating lobes. This will be done by showing the design process of a 1×16 linear array design that uses four 1×4 sub-arrays. Its design progress will include analytical, full-wave simulation, and measurement parts.
使用子阵列已经成为设计大型阵列天线的一种流行方法。使用子阵列简化了阵列设计,允许设计人员专注于较小的子阵列,并在阵列的其余部分重复它。由于子阵设计中的系统误差,在大型均匀阵中会出现异常的光栅瓣。因此,对于子阵列设计者来说,在将子阵列设计纳入更大的阵列之前,能够诊断出子阵列设计中的错误是很重要的。本文将分类并演示可能导致均匀阵列中出现光栅瓣的特定子阵列方向图畸变。此外,一个设计实例将介绍如何识别上述畸变可以用来诊断和防止光栅瓣的出现。这将通过展示使用四个1×4子阵列的1×16线性阵列设计的设计过程来实现。它的设计过程将包括分析、全波模拟和测量部分。

Various types of internal antennas suitable for digital TV receiver have been investigated. These include rectangular plate loop structure, 1/2λ monopole, and L-dipole. Evaluations of the internal antennas were done, numerically and experimentally, to obtain some electrical properties such as S11, VSWR, gain and radiation pattern. All the fabricated antennas are incorporated inside the TV receiver body. This allows more flexible, moveable, compact, and inexpensive construction of digital TV in the future.

As a planar-type wideband antenna being useful for UWB radio systems, the authors have previously proposed a leaf-shaped bowtie antenna. In this paper, we present a design of a leaf-shaped bowtie antenna in which a periodic patch-loaded grounded slab is used in order to realize a unidirectional beam over a wide frequency range while maintaining a low-profile configuration. In order to demonstrate effective performance of the presented configuration, fundamental characteristics of the antenna are investigated and revealed by the finite-difference time domain (FDTD) analysis and measurements.

A comparison of geometrically bound random arrays in euclidean space 欧几里得空间中几何约束随机数组的比较

Geometrically bound linear, planar, and volumetric random array topologies are analyzed through a probabilistic approach to study the topological impact on beam pattern. The analysis assumes randomly distributed elements with uniform distribution to evaluate the statistically averaged beam pattern for linear, planar (square and circular), and volumetric (cubical, cylindrical, and spherical) geometries used to bound the array. Results show that many simple geometries share analytical similarities due to symmetry. Numerical results of the average beam pattern show good agreement to analytical solution and are shown for comparison.
