PROJECT TITLE :

Parametric analysis of extended hemispherical dielectric lenses fed by a broadband connected array of leaky-wave slots

ABSTRACT:

In this study, the authors examine the properties of a broadband array of leaky-wave slots located within the focal plane of an extended hemispherical dielectric lens, to get many independent beams for imaging applications. The array performance is investigated over a four:one band. Parametric analyses are performed by varying the extension length of the lens and also the off-axis distance of the feed point. The results of those analyses offer helpful guidelines for the lens design. A spectral domain approach is used to characterise the field generated by the array, whereas a numerically economical physical optics algorithm is employed for the analysis of the lens. Simulations performed with Pc Simulation Technology Microwave Studio are used for the validation of the combined analysis ways.
