| Popis: | A pattern reconfigurable antenna array with two elements is designed in this paper. The antenna element is made up of a printed Yagi and feed structure with variable phase. By changing the states of diodes in the feed structure of these two elements, the far-field radiation phase of both elements can be changed. That is, the pattern reconfigurable function of the array is realized. In this way, the impedance bandwidth of array is 75.9% (2.7~6.0 GHz), in which the peak gain direction can be switched between -θ, 0 and +θ (θ = 10°~16° at different frequencies). With the simple reconfigurable structure, the peak gain direction can be adjusted according to demands. It can be applied to broadband investigation systems. To verify the feasibility, a prototype is fabricated, measured, and reasonable agreement between the simulated and measured results is obtained. |
