چکیده
Radiation Characteristics of a circular sector micro strip antenna (CSMA) designed for the 60 GHz millimeter-wave band an application is presented in this paper. The proposed antenna consists of a circular patch with sector slot excited by micro strip feeding 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 been performed for optimizing the different parameters such as slot angle, Feed point etc. for the best possible results. The proposed antenna configuration resulted in a bandwidth of 1.47 GHz covering the frequency range from 59.26 to 60.73 GHz, with a gain of 8.0334 dB at the 60 GHz resonance frequency. The CSMA proposed is characterized by its ease of manufacture, its miniature 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.
