After numerous antenna analyses ranging from monopoles to dipoles to eggbeater antennas, a crossed-dipole antenna with two elements 33 cm long and 90 degrees out of phase yields the most beneficial gain pattern for transmitting on the 70cm band. The antenna is circularly polarized and offers a near-isotropic gain pattern.
Abstract: In this letter, a new conductive composite tape-spring is proposed for CubeSat deployable antennas that is constructed using a glass fiber reinforced epoxy with an embedded copper alloy conductor. The tape-spring is bistable enabling the antenna to be elastically stable in both the deployed and stowed states. A dipole antenna is designed, simulated, and tested to prove the viability of the electrical properties of this material.
