Abstract: This paper proposes a coplanar waveguide with lower ground (CPWG)-fed reconfigurable beam steering antenna using a bended dipole and circular loop combined structure. The radiation patterns of the antenna head towards specific directions when the dipole and loop antenna are combined at a reasonable ratio. The proposed antenna can steer the beam directions by controlling two RF switches (PIN diode). The maximum beam directions are +30°, 0°, and -30° in the azimuth plane, and the overall gains are 4.0-5.4 dBi in the operation bandwidth of 2.39-2.59 GHz. © 2012 Taylor & Francis.
