“…We thus show that pseudopotentials enable one to predict the performance of finite dipole arrays using information from infinite dipole arrays. Note that, due to our use of pseudopotentials, the present work differs from works by others [1], [8], [15]- [17], [19], [20], [22], [23], [50]- [55], who also use infinite arrays to analyze finite arrays. We indicate that our approach is not limited to dipole arrays by briefly comparing pseudopotential results to certain results [56] for parallel-plate waveguide arrays.…”

The results obtained by modeling an infinite linear array of electrically short dipoles by an array of pseudopotentials (the pseudopotential is a quantum-mechanical analog of the dipole) can be used for the analysis of finite linear dipole arrays. This idea is utilized to investigate properties of finite arrays such as resonances, grating lobes, and end effects. For a wide range of parameter values, it is found that the pseudopotentials can quantitatively describe all aforementioned properties of the actual finite array. Certain extensions to waveguide arrays are discussed.

“…Beyond that, the gain can only be increased by increasing the diameter [18]. The same phenomenon is seen in array antenna elements such as the BoR-element [27], which also becomes more efficient when made longer, but it is ultimately limited by the area occupied in the xy-plane. In addition to the above, it is also important to compare the available gain for a fixed diameter when considering sparse arrays consisting of multiple lenses.…”

Abstract-This paper presents a study of planar silicon lens antennas with up to three steppedimpedance matching regions. The effective permittivity of the matching regions is tailor-made by etching periodic holes in the silicon substrate. The optimal thickness and permittivity of the matching regions were determined by numerical optimization to obtain the maximum wideband aperture efficiency and smallest side-lobes. We introduce a new geometry for the matching regions, referred to as shifted matching regions. The simulation results indicate that using three shifted matching regions results in twice as large aperture efficiency as compared to using three conventional concentric matching regions. By increasing the number of matching regions from one to three, the band-averaged gain is increased by 0.3 dB when using concentric matching regions, and by 3.7 dB when using shifted matching regions, which illustrates the advantage of the proposed shifted matching region design.

This article presents a wideband wide‐angle tapered slot array (TSA) antenna with no grating lobes in the 6–18 GHz band and the required scan range (azimuth angle ≤ |42.5°|, elevation angle ≤ |22.5°|). The unit element in the array antenna is a modified type of the existing TSA elements. We studied the various parameters for the proposed structure to investigate their effect. A single antenna and an 8 × 8 array antenna with the proposed structure were designed and fabricated. The validity of the proposed structure and design procedure has been verified by the agreement between the simulated and measured results.
