关于蝶形宽带微带天线的设计
索引:蝶形宽带微带天线. 设计方案 排列效率
摘要:现在提出一种基于绝缘体衬底的有限长度的宽带微带天线的设计方法。这种方法快速、对计算精度要求较低,是建立在一蝶形天线进行二等分而形成的两个梯形天线的 。首先设计出单边的梯形部分,然后制作出相同的另一部分并在其顶点处将其连接。与理论计算相比在X波段上实验测量表现得很好。其有效带宽达到10.6%
(One approach to an antenna book starts with a discussion of how antennas radiate. Beginning with Maxwell’s equations, we derive electromagnetic waves. After that lengthy discussion, which contains a lot of mathematics, we discuss how these waves excite currents on conductors. The second half of the story is that currents radiate and produce electromagnetic waves. You may already have studied that subject, or if you wish to further your background, consult books on electromagnetics.The study of electromagnetics gives insight into the mathematics describing antenna radiation and provides the rigor to prevent mistakes. We skip the discussion of those equations and move directly to practical aspects.)

walsh-decoding-with-hamming-distance
Aim: do walsh coding with hamming distance.To compare WALSH decoding for synchronous CDMA with decoding using hamming distance.
a) System should be supplied with correct/ corrupted version (one/ two bit) of transmitted walsh code(s)
b) System should also have table for correct codes(walsh codes)
c) System should ab able to deocde the same using hamming distance property.
d) Copmare resutls for corrupted code(s) to check the efficacy of WALSH decoding technique (as in above experiment) compared to hamming distance decoding.
