The size of satellites are becoming smaller in the progressing years due to the evolution of new technology and applications. In this scenario, miniaturized, low-weight, low-profile, robust antennas are essentially required such that they should be in the order of size of compact satellites with high reliability and less bulk. Employability of the lower-frequency UHF/VHF antennas for establishing communication is limited due to their large size. Moreover, monopole and 3D antennas are also not qualified for small satellite applications, owing to their complex operation and high possibility of failure. In such systems, planar compact antennas are immensely required so that it can be accommodated on a planar surface in the satellite systems. Metamaterial antennas are best possible solutions to be deployed effectively in small satellites as they offer planar configuration and compactness simultaneously. CPW technology facilitates to keep the signal line/patch/radiators and ground planes aside on the same plane instead of having the ground plane on the other plane. Hence, this technology provides another design freedom to antenna engineers to design the antenna entirely in the same plane. This chapter focuses on designing two different CPW-fed-based antennas based on metamaterials to showcase their suitability in the S-band and C-band small satellite applications. In the first work, an epsilon-negative transmission line (ENG-TL)–based antenna using two split-ring resonators is presented so as to work in the dual bands covering S-band. In another work, a novel antenna based on amalgamation of CPW-fed and backed ground plane is presented to achieve exceptional miniaturization.
