In this work, planar circular-polarized (CP) antenna operating at 2.40–2.45 GHz is presented. The developed antenna is suitable for the installation on a Nanosatellite or CubeSat, which are usually considered lightweight satellites (below 10 kg), and used for the different observation purposes. The following requirements for the antenna design are considered: operation in S-band (2–4 GHz), circular polarization, and 10 \(\times \) 10 cm\(^{2}\) ground platform for the antenna installation. Developed patch antenna is theoretically studied using high frequency electromagnetic field simulation software, then it is manufactured, and a set of validation measurements is performed. The radiation characteristics, matching and losses are presented. The simulated and measured results correspond well to each other and fit the requirements. The \(S_{11}\) of the antenna is below \(-6\) dB in the desired frequency range and the simulated axial ratio values vary from 3 to 5.8 dB. The minimum measured axial ratio is 1.5 dB at 2.35 GHz. The results indicate that this antenna could be a good candidate for the installation on a nano-satellite chassis.
