Abstract

There have recently been extensive studies of small‐size microstrip antennas. Some of these small antennas maintain gains of 5–6 dBi, whereas others have gains of 0–1.5 dBi. One important antenna parameter is the radiation efficiency. There have been very few studies on this parameter for small microstrip antennas. This letter presents measurements of several of these structures introduced earlier, with the use of the Wheeler cap method. The highest efficiency measured was about 96%. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 33: 112–113, 2002; Published online in Wiley InterScience (www.interscience.wiley.com).

A rigorous analysis of printed circuits and antennas requires a great computational e!ort, due to the necessity of an accurate modelling of large metallic structures, including radiating patches and feeding lines. The computational e!ort increases if we have to deal with radiation phenomena in larg
