A 2.4 GHz cross rhombic antenna for a cube satellite application

Abstract

We present design and construction results of a 2.4 Ghz cross rhombic antenna to be used in a cubesat. Computational design agrees with experimental results after its construction. cross rhombic antenna is a novel planar structure of our own design, presenting circular polarization and medium gain; it is built over a RF60A substrate with εr=6.15, decreasing its size to fit the required dimensions of satellite. A special characteristic of this design is the enhancing of operational bandwidth using a technique we have been studying, related to softening the structures with sharp edges. Results show applicability and success of our technique. © 2014 Jorge Sosa-Pedroza et al.
