Design and Analysis of Compatible Embedded Antenna for Mini Satellites

Abstract

An embedded antenna is a metallic conductor embedded in a dielectric material whose dielectric constant is greater than 1, Ex: Microstrip patch antenna (MPA). In this paper, minisatellite antenna is presented. MPA antennas offer an ideal solution for satellite communication requirements due to their light weight and low profile. The design includes embedded single layer staircase feed, patch with three shapes square, half-bow tie, and full bow tie with defected ground structures (DGS) with FR4 Epoxy substrate thickness 1.59, mm. The proposed antenna achieved sufficient return loss for LEO satellites. The minisatellite aims to acquire data about high voltage discharge phenomena in LEO. This will enhance the understanding of satellite charging, overall reliability etc. The antennas operate at different frequencies in S-band, C-band, and X-band. The tool employed to design and simulate MPA is HFSS version 13.0.
