This paper proposes a radiation pattern and frequency reconfigurable antenna using four PIN diodes. The antenna structure is based on the Padovan sequence of nine squares on the patch and four ones on the ground. In this way, the antenna's radiation pattern can be recognized at +52° and 27°. Also, the reconfigurable frequency of the proposed antenna can change from 5 GHz to GHz. The total antenna size is rather small, which is x 35 x mm3 . Besides, the antenna can achieve rather high efficiency and a quite good bandwidth at almost operating bands. |
