Axial ratio is defined as the ratio of the major to the minor axis of the polarization ellipse. 1.Ex andEy are orthogonal complex-valued field components. If either is zero, HFSS treats the field as linearly polarized. However, if neitherEx andEy is zero: 2. Compute circular componentsE-...
各位大佬,我想问一下..各位大佬,我想问一下关于轴比的单位,我看一般用dB(Axial Ratio Value),我用的是min(dB(AxialRatio Value)),这样从实际准确性上来说妥不妥当?
From the measured results, the proposed array can give an axial ratio of lower than 1 dB and a front-to-back ratio of higher than 12 dB within a 10 dB-return-loss bandwidth of >16%. Simulation results obtained with high frequency structure simulator (HFSS) also agree well with the ...

The proposed antenna presents a dual-band monopole antenna with a wide axial ratio bandwidth, by using the modified ground plane. The tilted inverted L-shaped strip with an angle of α is printed on the FR4-epoxy substrate and is excited by the microstrip feedline. The overall dimension of ...
HORN ANTENNASLOTThis paper presents an improved design and implementation of broadband circularly polarized (CP) antenna that features a broad bandwidth and wide axial ratio (AR) beamwidth. First, the relationship between the three parallel plates (rectangular, semicircular, and semielliptical) and θ...
