Abstract:

Tapered slot antennas (TSAs) have seen considerable application in the millimeter-wave portion of the spectrum. Desirable characteristics of TSAs include symmetric E- and H-plane antenna patterns, and broad non-resonant bandwidths. We investigate extension of TSA operation toward higher frequencies in the thermal infrared (IR), using a metal-oxide-metal diode as the detector. Several different infrared TSA design forms are fabricated using electron-beam lithography and specially developed thin-film processes. The angular antenna patterns of TSA-coupled diodes are measured at 10.6 micrometer wa

Abstract:

The aim of this study is to investigate the effects of changes in the physical parameters of tapered slot antennas (TSA) on their radiation characteristics and also to explore the possibility of reconfiguration in the radiation pattern of TSA by switching between two different types of tapering. There are mainly three physical parameters that affect the radiation pattern of TSAs. These are antenna length, aperture width and the ground extension. After designing a wideband microstrip line to slot line transition, the effect of antenna parameter variations on the beamwidth and sidelobe level of

Abstract:

A simple and novel solution is proposed to overcome the main beam splitting of the tapered slot antenna (TSA) fabricated on a thick substrate with high dielectric constant. It utilised arrays of metal strip gratings to reduce the undesirable surface waves. Measured result of a 10lambda0 long 35GHz linear taper slot antenna (LTSA), shows a dramatic improvement in the radiation pattern and a measured front-to-back ratio of 20dB for both the planes. Further analysis shows that the metal strip gratings help to improve the directivity and return loss of shorter LTSAs. Comparing with a basic LTSA wi

Although the antenna, used either for a single element or for 5 x 5 multibeam array elements, had the gain loss which was estimated as about one quarter of the total radiated power, due to cross-polarized radiation, the antenna yielded wide bandwidth, high gain, and high aperture efficiency. A new method to calculate the directivity and efficiency was developed, which is based on integration of co- and cross-polarized patterns in three planes. The directivity and effi
