Abstract :
A Yagi loop antenna, which is built on an origami spring structure, is presented here. The Yagi loop array can be compressed to 5 cm length by a servo motor which can reduce nearly 70% of the volume of the array. The antenna´s body is 20.5 cm long when it is expanded to the working state. The physical parameters of the antenna such as loop´s radius and distances between loops are analyzed. The antenna is designed to work at 1.31 GHz. A directional realized gain of 10.4 dBi is observed. The measurements agree well with the designed simulation model.
