Kama Huang - 《IEEE Transactions on Antennas & Propagation》 被引量: 32发表: 2010年 MICROSTRIP ANTENNA AND ARRAY ANTENNA USING THE SAME PROBLEM TO BE SOLVED: To provide a microstrip array antenna less susceptible to loss of an electrical connection between radiation antenna elements and a feeding...
Figure 2ashows the radiation pattern of a basic dipole. Its figure 8 pattern causes most power to be radiated broadside from the antenna element and also some in other directions, except in those directions at the ends of the antenna elements. By using multiple antennas in an array, the radi...
Directivity is a useful metric when comparing antennas as it defines the ability to focus radiated energy. Gain has the same pattern of directivity, but gain includes the antenna losses. Prad is the total power radiated, Pin is the input power to the antenna, and k accounts for losses in ...
One of the challenges in effectively implementing an advanced precoding scheme to a large-scale array antenna is how to reduce the mutual coupling among antenna elements. In this paper, a new concept that is called array-antenna decoupling surface (ADS) for reducing the mutual coupling between ...
c= conformalArraycreates a conformal antenna array using the default antenna elements and element positions. The default elements are a center-feddipoleobject resonating around 700 MHz and a center-fedbowtieTriangularobject resonating around 403 MHz when isolated. The antennas are spaced 0.15m apart ...
Phased Array Antennas 来自 IEEEXplore 喜欢 0 阅读量: 96 作者: C Blake 摘要: The theory of array antenna design has matured such that the tools are now available to design elements with predictable performance and to verify this performance with high confidence. The antenna feed is of equal ...
如果无线系统采用 N >1 个传感器(换能元件、接收器、天线等(transducing elements, receivers, antennas, etc)阵列,这些传感器分布在三维实空间中,具有共同的参考点(共同原点),则该系统称为阵列系统(array system)。 Monostatic Antenna Array Radar 考虑一个单基地雷达(monostatic radar),其天线阵列由 N 个元素组成...
Instead, current phased array antennas comprise antenna elements having identical radio frequency (RF) signals except for relative phase, which is limited to 0 to 2π radians. That is, relative time delays are limited to one period of the radio frequency being used. Nevertheless, some time-...
