Radial line slot array antenna

A log-periodic antenna having a layer of dielectric media interposed between a microstrip log-periodic portion and a slot log-periodic portion where an array of two or more log-periodic antennas that may be placed about vehicles, such as …

Design of Ka Band Downlink Radial Line Slot Array Antenna ... A Radial Line Slot Antenna (RLSA) is a novel planar array. This paper discusses the key design of RLSA, that is, the suppression of reflection in the antenna and the slot coupling control. Design of a slot-coupled radial line helical array antenna ... An eight-ring radial helical array antenna based on a novel slot-coupled structure is designed and simulated. The novel coupling structure has the advantages of high power-handling capacity and excellent coupling ability. The simulation results of the array antenna agree well with theoretical calculations, and the aperture efficiency is about 78.1% when the beam is in the normal direction.
