A low-cost and portable one-port vector network analyzer (VNA) which covered operating frequency between 50 MHz to 1 GHz is developed for vector reflection coefficient measurement of the communication devices. A four-port reflectometry technique is implemented in the VNA module design. To collect and analyze data from the VNA, graphical user interface (GUI) is designed using LABVIEW software. In addition, open-short-load calibration technique was programmed in GUI to counterbalance systematic errors of the VNA. The performance of this designed VNA is approximately equivalent to the available commercial VNA.
