Abstract :
Wirelesssignal reception at the place affected by distance, topology, environment and weather. To strong the signal that receive so it?s need the antenna. In relation to thisobjective report is to modify a wireless signal booster antenna product that cost is cheap and easy to apply. In this research will explain how to improve the antenna performance USB Wireless Device and how to analyze it. In this test used a USB Wireless device Standard TP-Link TL-WA727N and Flat Panel Antenna assemblies. Device USB Wireless has a speed until 150 Mbps with the wirelessstandard802.11 n and distanceof catching radio signals maximum of only 150 meters depending prohibitive factor, then the USB wireless will be added the flat panel antenna assemblies with dimeter of 32 x 30 cm and the distance catches a radio signal up to 300 meters
