    Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basic steps of defining a magnetic frill voltage generator for a dipole antenna, and it also compares the resulting antenna impedance with known results.

  • DDA使用教程

    DDSCAT 7.3 is a freely available open-source Fortran-90 software package applying the “discrete dipole approximation” (DDA) to calculate scattering and absorption of electromagnetic waves by targets with arbitrary geometries and complex refractive index. The targets may be isolated entities (e.g., dust particles), but may also be 1-d or 2-d periodic arrays of “target unit cells”, which can be used to study absorption, scattering, and electric ?elds around arrays of nanostructures.

  • 使用PCB設計天線 對于2.4G天線設計詳細描述

    v> 目前最常見的藍牙天線有偶極天線(dipole antenna),倒 F 型天線(planar inverted F  anternna)、曲流線型天線(meander line antenna)、微小型陶瓷天線(ceramic antenna)、液晶 聚合體天線(lcp)和棒狀天線(2.4G 頻率專用)等。由于這些具有近似全向性的輻射場型 以及結構簡單、制作成本低的優點,所以非常適合嵌入藍牙技術裝置使用。
