| Abstract: | The growing need for compact and more powerful antenna design for CubeSats has led to many creative solutions. To maximize surface area and handle high data rate, this paper discusses the development of reduced weight optically transparent (OT) meshed circularly polarized (CP) antennas designed for X band applications. Two analytical models of such transparent antennas are proposed. These transparent radiating elements are to be placed on the photovoltaic (PV) modules, utilizing the available space without affecting the renewable energy generation for the satellites. The goal is to design a transparent antenna where both radiating as well as reference trace layers are meshed, and quartz‐made transparent dielectric material is used, operating at a frequency around X band with at least 10 dBi antenna gain. Circular polarization is achieved using perturbations, and a CP bandwidth of at least 50 MHz is achieved. This paper explores the effects of changing the mesh wire width on the antenna characterization metrics, comparing results with a solid, nonmeshed antenna. The meshed wire antenna has a reduced overall weight, as a bulk amount of copper is removed when meshed. The optical transparency has been achieved more than 80% for the narrowest width of the mesh, maintaining a 50 MHz CP bandwidth and 10 dBi right hand circular polarization (RHCP) gain. The outcomes of this study have proven to be an efficient, lightweight, and transparent antenna solution by allowing more experimental instruments to be installed on the chassis of nanosatellites.
