Summary:
An antenna composed of two leaf-like bent conducting strips, designated as the BeToL, has been investigated in [1]. This antenna is excited from the bottom end of one leaf strip, with the other leaf strip shorted to the ground plane and acting as a parasitic element. Investigation shows that the BeToL exhibits a unidirectional radiation beam. An extended version of the BeToL is found in [2], where the number of bent leaves is increased to four and the antenna is designated as the BeFoL. The BeFoL is used as an element in a mobile communication array antenna. The radiation characteristics for the BeFoL array antenna are analyzed and discussed in detail in [2]. This paper is a sequel to [2], presenting a novel design for a reconfigurable antenna [3]-[6]. First, a BeFoL with a conducting ground plane of infinite extent is briefly summarized. Second, the radiation characteristics for a BeFoL with a finite-size ground plane are analyzed. Lastly, the finiteground plane is bent and the beam direction from the BeFoL with the bent ground plane is discussed.
