Danger microstrip patch antenna for fixed satellite applications

摘要

This paper proposes the rare innovative design and a brief discuddion on results of a dual band danger microstrip patch antenna that can be employed for multiple space applications. The design symbolizes the danger indication normally viewed on road sites mostly on electric poles. A 80 mm × 105 mm FR4 epoxy substrate with a relative permittivity of 4.4 and a thickness of 1.6 mm is used. In addition to being a part of the design, the circular slots also offer a reduction in the area occupied by the patch. The probe feeding technique has been utilized. HFSS v-15 software is used for simulation. The designed antenna has a peak gain of 1.6 dBi at 2.7 GHz with a bandwidth of 12 MHz that may be used in earth exploration satellites, radio astronomy, space research and aviation purpose. Additionally, a maximum gain of 4.9dBiat 4.57 GHz with a bandwidth of 4.61 MHz is obtained that can be used in fixed satellite applications.
