Abstract :

The sinuous antennas have a numerous applications in military and civil systems such as direction finding systems and reflector feeds due to their superior broadband characteristics and simultaneous polarization capability. In this paper, design, construction and measurements of planar sinuous antennas are investigated for 1–5 GHz frequency range. Feeding sections of this antenna are realized by using microstrip tapered baluns. With an increase in the application of UHF frequency usage in the spacecraft sphere, it is required to extend feed capability in the lower operating frequency range of facility. In view of this, it was proposed to design and develop an UWB antenna operating in the frequency band from 200 MHz - 1 GHz so that facility measurement capabilities can be extended.In this paper, design aspects of antenna, feeding network, fabrication, pattern and gain measurement procedure are discussed. Comparison of simulated & measured pattern and gain values shows good match between them. Key words: Sinuous antenna; Microstrip tapered balun; Dualv Polarization, Advanced Design System, High frequency Structural Simulator, Radar Cross Section
