60 GHz Band Small Aperture Conical Beam Radial Line Slot Antennas
A more beneficial design is that of the radial line slot array (RLSA) type antenna. Advantages of this antenna include its high radiation efficiency, low profile, low cost and rear-mounted feed. The prototype development starts with the selection of the cavity's dielectric material and construction of the coaxial-to-waveguide transition. Radial Microstrip Slotline Feed Network for Circular Mobile ... antenna and a Ka-Band printed dipole [1]. In addition, a L-Band mechanically steered microstrip array [2], a L-Band microstrip phased array tracking antenna for mounting on a car roof [3] and a X-Band radial line slotted waveguide antenna [4] have been demonstrated. In the above electronically scanned printed Radial line s lo t array antenna at 28 GHz with modified ...
This paper discusses how to design a Radial Line Slot Antenna (RLSA) whose waveguide is filled with high loss dielectric materials. We introduce a new design for the aperture slot coupling synthesis to restrain the dielectric losses and improve the antenna gain.
