An S-Band Micro-Strip Patch Array Antenna for Nano-Satellite Applications

It's the generation of tiny satellites which basically needs all its components to be miniature. The product proposed here is one such component, a microstrip patch antenna array operating at 2.2GHz and 2.45GHz S-band frequencies. This real-time project work deals with a rectangular patch antenna operating at S-band frequencies which is mainly focused to be applicable for the NIUSAT, which is a nano satellite. The proposed S-Band Patch antenna is being designed and simulated using ADS software. Obtaining optimum bandwidth efficiency by choosing suitable size without affecting any other parameters of the antenna is the challenge taken over in this project. The low profile, less weight patch antenna has two antenna elements of physical dimension 37x27x1.25mm separated by 10mm. The substrate material being used is Alumina with dielectric constant 9.6. This antenna is designed to be used for TTC and payload downlink purposes. The designed patch array antenna meets all the parametric needs for a Polar orbiting satellite at Low Earth Orbit (LEO) region.
