Cubesat whip antennas function as resonant monopole antennas deployed via spring mechanisms.
The retrieved literature mentions CubeSat whip and monopole antennas and discusses deployment approaches, but no single source fully establishes both resonant monopole functionality and spring-based deployment mechanisms together.

A Survey on CubeSat Missions and Their Antenna Designs. 2022. https://doi.org/10.3390/electronics11132021
CubeSats are a class of miniaturized satellites that have become increasingly popular in academia and among hobbyists due to their short development time and low fabrication cost. Their compact size, lightweight characteristics, and ability to form a swarm enables them to communicate directly with one another to inspire new ideas on space exploration, space-based measurements, and implementation of the latest technology. CubeSat missions require specific antenna designs in order to achieve optimal performance and ensure mission success. Over the past two decades, a plethora of antenna designs have been proposed and implemented on CubeSat missions. Several challenges arise when designing CubeSat antennas such as gain, polarization, frequency selection, pointing accuracy, coverage, and deployment mechanisms. While these challenges are strongly related to the restrictions posed by the CubeSat standards, recently, researchers have turned their attention from the reliable and proven whip antenna to more sophisticated antenna designs such as antenna arrays to allow for higher gain and reconfigurable and steerable radiation patterns. This paper provides a comprehensive survey of the antennas used in 120 CubeSat missions from 2003 to 2022 as well as a collection of single-element antennas and antenna arrays that have been proposed in the literature. In addition, we propose a pictorial representation of how to select an antenna for different types of CubeSat missions. To this end, this paper aims is to serve both as an introductory guide on CubeSats antennas for CubeSat enthusiasts and a state of the art for CubeSat designers in this ever-growing field.

Three systems are compared: A standard system with separate transmit/receive dipoles, a dual-band dipole for both transmit and receive and a dual-band monopole, which uses the body of 1U cubesat (10 × 10 × 10cm) as a “groundplane”. Additionally it is demonstrated that with appropriate feed the dipole might be used in monopole configuration in case of deployment system malfunction.

Design, Analysis and Testing of Monopole Antenna Deployment Mechanism for BIRDS-2 CubeSat Applications. 2019. https://doi.org/10.1088/1742-6596/1152/1/012007
This paper presents an approach to design a feasible and reliable monopole antennae deployment mechanism for CubeSat applications. Nano-satellite has faced problems in designing antennae deployment system due to space and deployment mechanism constraints. In BIRDS-2 CubeSat, the nichrome wire burning release mechanism was used when activated, it will be heated up and thermally cut through fishing line, allowing the two monopole antennas to be deployed on +Y board and at +Z axis direction of the satellite. These antennae involved amateur radio frequencies in UHF and VHF bands due to its low cost and high accessibility by the end users. The UHF frequency band was used for command uplink, mission, telemetry, and CW beacon downlink whilst the VHF frequency band was used specifically for APRS-DP/S&F-RDC mission for both uplink and downlink. In order to achieve the effectiveness of the BIRDS-2 CubeSat communication system agreed with the link budget estimation, the dimensions of antennae on the CubeSat structure depend on the required gain and operating frequency. The paper discusses detailed results of mechanical and electrical interfaces of the two monopole antennas deployment mechanism with the satellite body and the nichrome wire burning release mechanism analysis. The tests results of the mechanism were analyzed particularly on the deployment time and the nichrome wire temperature differences.
Microwave Patch Antenna Placement on 6U CubeSat. 2024. https://doi.org/10.23919/ICEP61562.2024.10535673
Kyushu Institute of Technology (Kyutech) is developing a 6U CubeSat that is named “VERTECS” (Visible Extragalactic background RadiaTion Exploration by CubeSat). This is an astronomical CubeSat designed to reveal star formation history by observing visible extragalactic background light [1] and the first satellite for Kyutech to rely on not UHF (around 400 MHz) but only microwave (>1 GHz) to communicate between the satellite and ground station. Microstrip patch antennas are adopted on this CubeSat due to desired characteristics such as low profile, lightweight, and non-deployable structure. However due to the performance of the microstrip patch antenna is limited such as directional radiation pattern and narrow operational bandwidth, the placement of the antenna on CubeSat is more critical compared to that of the conventional antenna for UHF communication, such as dipole and monopole antenna. In this paper, we describe choosing the antenna placement while considering antenna performance, including the coupling of transmission and reception antenna.
