ABSTRACT
Radiation Characteristics of a circular sector micro strip antenna (CSMA) designed for the 60 GHz millimeter-wave bandan application is presented in this paper. The proposedantenna consists of a circular patch with sector slot excited by micro stripfeeding technique.Substrate material chosen here is the Kapton which is a polyimide used in high performance flexible printed circuit and thermal blankets on satellites, and various space instruments.Parametric studies have beenperformed for optimizing the different parameters such as slot angle, Feed point etc. for the best possibleresults. The proposed antenna configuration resulted in abandwidth of 1.47 GHz covering the frequency rangefrom 59.26 to 60.73 GHz, with a gain of 8.0334 dB at the60 GHz resonance frequency.The CSMAproposed is characterized by its ease of manufacture, itsminiature dimensions and its simple design. The presence of slot makes impedance variations along the circumference so that the antenna can be fed using a micro strip line.
