Tutorial Workshop at Bangkok on August 7, 2012

The day before TJMW2012 (2012 Thailand-Japan Micro Wave), AP tutorial workshop, entitled "Fundamentals of antenna measurement technique", will be held at the same venue. It is sponsored and organized by the technical committee on antennas and propagation, IEICE, Japan.

Date & Time

9:30am to 12:00am (noon) on August 7, 2012.

Venue

Chulalongkorn University, Bangkok, Thailand

Title

Fundamentals of antenna measurement technique

Speaker

Dr. Nozomu Ishii
Niigata University, Japan

Abstract

With the advent of the vector network analyzer, the accuracy of the input impedance measurement of small antennas has been improved. However, the characteristics of the small antennas are still sensitive to the surrounding environment, it is necessary to pay sufficient attention to the measurement even if the performance of the instrument were improved. In this tutorial workshop, first, the importance of understanding the basics required in the measurement of the small antennas, identifying the error factors and the uncertainty are described. Second, the precautions on the handling of the cables and connectors used from the VHF/UHF band to the microwave band are enumerated. The technique of the input impedance measurement of the antenna using the vector network analyzer, including the electrical length compensation, is overviewed. Finally, the radiation pattern measurement of the antenna and corresponding error factors are discussed.
