In this paper the printed loop antenna is proposed for high frequency radio frequency identification (HF-RFID) systems (13.56 MHz). The proposed antenna is designed on the printed circuit board (PCB). The antenna structure consists of printed semi-spiral loop with rectangular structure patch at the middle of loop. It can provide the magnetic field distribution to cover the operating area with various directions that can improve the communication performance between reader and various tag orientations. From the measured results the proposed antenna has more efficient than the printed spiral loop antenna

Thesis this has the objective for design build and test ability in the work of set propeller wind generator by divide recording is 3 period in morning noon and evening each phase 1 hour record speed wind value capacity air value and electrical resistance every 10 minute. Of the periment form wind nature source and model with electric fan. The result stud makes to know that propeller at have property that is appropriate area stet experimental at wind speed 2 – 2.5 m/s is propeller make from pipe PVC by propeller has length 1.30 m. the area in front cut a propeller 0.16 m. through a propeller the corner twists in installation propeller
