Here is an idea for a dipole antenna! DIY Dipole antenna! By 100sideprojects, August 9, 2017 in Do It Yourself.
A typical CubeSat can only transfer 1.8 MB of data per day (combined uplink and downlink). Highly detailed satellite images are approximately 3 GB per square mile. That would take over FOUR YEARS to transmit one square mile! The small overlay size would allow the transmission of up to 66 different regional annotations in a single day. SURO-LC deploys a formation of nine spacecraft in a low relative-drift Lissajous orbit at SEL2, 1.5 million km from earth in a radio clean environment. Eight spherically distributed Cubesat daughters, equipped with 3 orthogonal dipole antennas, form a distributed interferometric radio telescope.
CubeSats are used for space research, but their low-rate communication capability limits functionality. As greater payload and instrumentation functions are sought, increased data rate is needed. Since most CubeSats currently transmit at a 437 MHz frequency, several directional antenna types were studied for a 2.45 GHz, larger bandwidth transmission.

Nov 26, 2020 · These antenna types, usually parabolic dishes or helical-wire, trade wide-directivity for high-gain which is why they have to track the satellite accurately. A simple fixed dipole or monopole is nearly omnidirectional but has very little gain. It is the output power when a signal is concentrated into a smaller area by the Antenna. The EIRP can take into account the losses in transmission line, connectors and includes the gain of the antenna. It is represented in dB. Enter the transmitted power, cable loss and antenna gain to calculate the EIRP (Effective Isotropic Radiated Power).

Many CubeSats settle for simple dipole antennas communicating in the S-band. While easy to implement, these simplistic satellite communications arrays limit the maximum data transfer to no more than 2 – 5 Mbps. For future CubeSat applications (formations of satellites, interplanetary missions), the communications system must be more advanced. DAVE is a 1U CubeSat spacecraft, measuring approximately 10x10x11cm.
