A design of radial line slot array antennas using the specification of panel antennas

Abstract RLSA antennas were suggested by several researches as Wi-Fi antennas in addition to panel antennas. [...]this paper researched the possibility of this suggestion. The effect of small number of slots is the capability of slots to radiate power into space is linearly reduced, so that increasing reflected power at the perimeter of RLSA antennas, thus lead to the increase of reflection coefficients. The material and the values of all feeder structure parameters are listed in Tables 3 and 4, respectively. f. Drawing the antenna: Since the structure of RLSA antenna is complex with hundreds of slots, so it is time consuming to draw this antenna manually in microwave simulation software. [...]in order to speed the drawing process, we develop a VBA (Visual Basic Applications) program.
