This paper presents a mechanically reconfigurable reflectarray with height adjustment for phase compensation. We designed, fabricated, and measured a prototype of 11×11 elements with microcontrollers to verify the feasibility of the proposed reflectarray. Simulated results show that the phase curve of the unit has good linearity and exhibit broadband characteristics. The maximum phase shift of the unit reaches about 200° at a center frequency of 16 GHz, which meets the requirement of a reflectarray with 1-bit phase quantization. Experimental results show that the gain of the proposed reflectarray is 17.7 dBi, with beam scanning range of ±50°. The proposed configurations can be used for a low-cost beam scanning antenna in wireless communication.
