Ultrathin and Compact Broadband Printed Monopole Antenna with Steady Radiation Pattern for SHF Satellite Communication
This paper presents a numerical analysis of an ultrathin and broadband printed monopole antenna for SHF satellite communication applications including VSAT. The antenna is designed by engraving a jigsaw puzzle with a 50 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\Omega$</tex> microstrip feed line on a 1 mm thick FR4 substrate terminated by a partial ground plane. The proposed antenna has a low profile of O. <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$5\lambda_{0}\times 0.325\lambda_{0}\times 0.025\lambda_{0} (20 \times 13\times 1mm^{3})$</tex> at the center frequency of 7.5 GHz. The numerical analysis of the antenna achieves a bandwidth of 5. 55 GHz and a fractional bandwidth of 74.15%, efficiently covering the frequency range from 4.71 GHz to 10.26 GHz, making it suitable for SHF satellite communication applications. The antenna delivers an average gain of2. 9 dBi and an efficiency greater than 90% with a steady omnidirectional radiation pattern within the operating range.
