Radial line slot antenna design

Abstract—We describe the design of a radial line slot array antenna with a shaped and focused near field. The antenna is designed in such a way to control the side lobe level and beamwidth of the normal component of the electric field with respect to the radiating aperture. The design procedure consists of two steps. Radial line slot antenna - HUOR OU HOK [0009] This radial line slot antenna has many advantages, and is expected to play an important role as a millimeter wave band antenna for mobile communication, including radio LAN, in the near future. [0010] The name of the radial line slot antenna is often simply referred to as “RLSA”, which stands for Radial Line Slot Antenna.

The required gain is 40 dBi for this design, and the antenna is designed to maximize the gain at the central frequency. Both patterns are obtained with different excitations of the radial line slot antenna (RLSA). Basically, if the slots are placed in concentric rings, when the RLSA is excited in the centre, a conical or difference beam is

the antenna aperture in this case. A radial line slot antenna (RLSA) for surface-wave-coupled plasma (SWP) is a promising candidate to this end. A novel slot arrangement in the aperture, consisting of densely arrayed transverse slots, was fabricated and tested. Radial Microstrip Slotline Feed Network for Circular
