Modelling of Slot Coupled, A Circular Microstrip Patch Antenna Elements
Abstract:The work described in this report has been done at ATR Optical and Radio Communications
Laboratories during my stay as a visiting researcher from December 1990 to April 1992. The research topic is related to the development of an active phased array antenna
for mobile communications at Ka- or Ku-frequency band.
An analysis method for slot coupled, circular microstrip patch antenna elements is proposed.
The method is well suited for CAD applications due to its low computational
requirements. Chapter 1 contains a brief introduction. A detailed description of the
theory developed is given in chapter 2. In Chapter 3 various results are discussed. The
comparison of measurements and calculated results gives an impression of the efficiency
of the method derived.
The author would like to thank Dr. Y. Furuhama, President of ATR Optical and Radio
Communications Research Laboratory and Dr. M. Fujise, Head of Radio Communications
Department, who provided the opportunity and the encouragement to carry out this work.
I am also grateful to the members of the antenna group for their valuable suggestions and
their constructive criticisms.
