Note: Only ActiveS(1:1) is displayed and it looks identical to the passive return loss [S(1,1)] from the Passive S-Parameter plot. Since Port 2 is not excited, it couples no energy to Port 1 which leaves Port 1’s self reflection as the only contribution to its Active S-Parameter...
where x are the length, width, and frequency attributes, y is the S11 parameter. For each query, the value θ is computed. Higher priority or preference is given to the point belonging to the training set vicinity of the x, rather than far vicinity points. Based on this, the cost funct...
In the rest of the paper, the single element design of the antenna is studied along with results in the form of a S-parameter, gain verses frequency plot, radiation pattern, and radiation efficiency. Afterwards, the MIMO configuration is analyzed, and comparison is performed between measured ...

The proposed antenna was first tested using a ground signal ground (GSG) probe; the measured return loss and radiation patterns of the fabricated prototype were in good agreement with full-wave simulations. Then, the LWA array was integrated with the photomixer chip using conductive epoxy threads...
3.2. Directive Element The design of the 3D super-directive antenna included multi-objective optimization, finding that the parameter set in Table 4 and Figure 5 brought the desired directivity, Return Loss, and Beamwidth according to the design requirements. Electronics 2022, 11, 2233 Table 4. ...
Then the Γ(φn, fm) matrix is generated by subtracting S-parameter-even from S-parameter-odd, where m and n denote the angular spot of every single spin. Here m = 1, 2, . . . , M and n = 1, 2, . . . , L/2. After collecting the data, the image of the interior of ...
