Abstract
This paper discusses a proposed antenna that can simultaneously reconfigure three different antenna properties. Those properties are radiation pattern, Half-Power Beamwidth (HPBW), and multibeam reconfiguration in the azimuth plane. To make all this feasible, a new unconventional Single Pole Six Throw (SP6T) switching network has been designed and analyzed. To introduce the reconfigurability, five switchable open stub lines are inserted into the switching network. It makes it feasible to drive the input power to the desired number of output ports by providing the impedance matching at power splitting points. At last, six curved printed dipole (CPD) antennas have been designed with the switching network. This antenna can be switched in 13 different cases. Among all, it produces six narrow beams, three wide beams, three dual beams, and one triple beam in the azimuth plane with an equal interval of angles. The measured result agrees with the simulation outcomes. The average gain in single wide and single narrow beams is 3.8 dBi and 4.8 dBi, respectively.
