Three methods of determining an antenna's efficiency are compared to measure the efficiency of three different antennas (two monopole antennas with attenuator and surface mount resistor, and modified folded monopole patch antenna). The purpose of this paper is to show that how the antenna efficiency can be measured accurately and comparable in reverberation chamber, traditional Wheeler Cap method and simulation from EDA tool.

Performance comparison of serial and corporate feeding networks in a rectangular Microstrip patch antenna array Soh, Ping Jack; Azremi, Abdullah Al Hadi; Dayang Khadijah, Hamzah; Rosemizi, Abd. Rahim; Mohd Taufik, Jusoh (Kolej Universiti Teknologi Tun Hussein Onn, 2006-12-19)One of the important aspects of a microstrip patch antenna array is the availability of the two feeding networks applicable to them, which are the serial and corporate feeding. A good impedance matching and optimal radiation ...
