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.
