Steered Patch arrays with a dielectric lens for collimation are well suited for vehicular applications due to their small form factor and effective sealing ability. In this paper we present an accurate analytical formulation of a patch array radiating in the presence of a hemispherical Dielectric lens based on spherical modal expansion (SME) and experimentally demonstrate an increase in directive...
In this paper, a four element and an eight element Microstrip array antenna with its printed feed network on a monolithic substrate is first analyzed for the predicted radiation patterns and compared with experimental results. The gain enhancement of the Microstrip array with dielectric lens is then studied. The advantage of using dielectric lens is observed to be 4dbi extra gain which translates...
This paper demonstrates collimation property of dielectric lens over a multiband set of small size patch antennas. The lenses provide collimation, wide angle steering and act as rugged radome providing an effective protection for the array. Lens antennas are better suited to an ocean environment and mobile communication applications. The primary radiator which is microstrip patch is designed at S...
In this paper we present an accurate analytical formulation of an electrically small aperture radiating in the presence of a hemispherical dielectric lens based on spherical modal expansion (SME) and experimentally demonstrate an increase in directive gain due to lens collimation. The analysis treats the lens as a scatterer. It utilizes techniques for radial translation and coordinate rotation of...
