2017 IEEE AP-S Student Design Contest: Cubesat Antenna

Travel to the 2017 IEEE AP-S USNC-URSI and win up to US $1,500!

Join the 8th IEEE Antennas and Propagation Society (AP-S) Antenna Design Contest! Design and build an antenna for a cubesat that enables high-performance communications with a ground station. The top 6 teams will receive up to US $2,500 in travel funds to attend the IEEE Antennas and Propagation Symposium in San Diego, California, July 9–15, 2017 to demonstrate their working systems. From these 6 teams, 1st, 2nd and 3rd place winners will be announced at the 2017 IEEE AP-S Awards Banquet at the conference and will receive cash awards of US$1,500, $750 and $250, respectively. Final reports will have the opportunity to be considered for publication in the IEEE AP Magazine. Important deadlines are November 28, 2016 and March 31, 2017.

Goal

Design and build a cubesat antenna for enabling high-performance communications with a ground station.

Specifications

  • The frequency range(s) covered by the antenna must utilize commonly used cubesat frequencies such as the VHF (145 MHz), UHF (440 MHz), S-band (2.2 GHz), X-band (8 GHz) and Ku-band (11.2 GHz). Higher frequency bands will not be considered. Wideband and/or multi-band designs are considered advantageous.
  • The antenna must be circularly-polarized (right-hand or left-hand CP) with an axial ratio as close to 1 as possible.
  • The antenna must be compatible with a 3U cubesat form factor (30cm × 10cm × 10cm). Antennas must reside within 5 cm of the exterior surface.
  • Deployable antennas are permissible so long as they obey the constraint above. If stowed within the satellite, the antenna must not occupy more than 50% of the interior volume of the cubesat.
  • The antenna should either maximize link gain or efficiently illuminate a wide coverage area from a 500 km low earth orbit (LEO) cubesat with a low transmit power (≤5 W). Examples include:
    • High gain patterns bearing in mind the need for beam steering at very high gain levels
    • Wide-coverage (isoflux patterns)
  • Teams will be required to demonstrate the following in their reports and final demonstrations:
    • An experimental model of an antenna on a suitable 3U cubesat mock-up (“tin-sat”)
    • Predictions and measurements of the antenna characteristics (gain pattern, input reflection coefficient with respect to 50 Ω) confirming the desired performance when mounted on the cubesat.
  • Merit will be assigned to designs based on the following criteria, equally weighted:
    • Creativity and justification of the design in relation to the specified usage scenario
    • Antenna performance in terms of bandwidth, pattern, and efficiency
    • Quality of the experimental model and results
  • Existing licensed software at the university (e.g., electromagnetic simulation software) or free software may be used. Any other commercial software used for the project should be included in the budget. The total production cost for the entire system must be less than US$1,500.

Eligibility

The team should consist of 2 to 5 students, with at least 50% being undergraduate students. For a 5-year Bachelor-cum-Master degree program, students in years 1 to 3 are considered undergraduates. Each team should be advised by a professional mentor who is a member of the IEEE AP-S, but the work needs to be done primarily by the students. No student or mentor should be involved in more than one team.

How to Submit Materials

Send all questions and materials to designcontest@ieeeaps.org with the subject line “2017 IEEE AP-S Design Contest.” Messages without this subject line may not be received. All submitted materials must be in PDF format according to the guidelines above.

The Application and Review Process

  1. All applicants must submit a preliminary design by November 28, 2016. It must include:
    1. A proposal limited to two pages and in 12-pt Times New Roman font that includes
      1. A detailed description of the link scenario being considered by the design.
      2. A detailed description of the system to be built.
      3. A bill of materials (up to US $1,500).
    2. A letter from a professional mentor, such as a professor or engineer in industry indicating agreement to supervise the project (the students being mainly responsible for doing the work). The mentor must be an AP-S member (please provide IEEE membership number) and must verify that all team members are graduate or undergraduate students at a university, college, or technical school. The proposal and letter must be integrated into a single PDF file named TeamName.pdf.
  2. The college of reviewers will assess each preliminary design based on likelihood of achieving the design goal and specifications, creativity, and quality of written materials. Six semi-finalist teams will be selected by December 19, 2016 and will receive US$1,500 each to build and test their designs.
  3. Each of the six semi-finalist teams must submit their final design by March 31, 2017 in the form of a video demonstration of the working system (≤ 5 minutes), and a final report (≤ 8 pages) in PDF format (≤ 5 MB file size). Submission instructions for the video demonstration will be provided later (some videos from previous contests are available on YouTube – search for “AP-S Student Design Contest”). The report should follow the two-column format of the IEEE Transactions on Antennas and Propagation and include:
    1. A detailed description of the use scenario envisions and corresponding design goals
    2. A list of parts and materials required, including where to obtain them and costs.
    3. Photos of the final system (including a scale to show how large it is).
    4. Measurements obtained using the system for the specified test scenarios.
    5. Biographies (100 words or less each) and photos of all design team members.
  4. Several Design Contest Judges will be appointed to assess each semi-finalist’s design based on achieved performance, creativity, completeness of the description, functionality of the system as determined by the video, and quality of written materials. Six finalist teams will be selected by April 28, 2017 to receive stipends of up to US$2,500 per team to travel to and attend the IEEE AP-S Symposium. The stipend is intended to cover equipment shipping costs and all expenses for one team representative; however, it may be divided among multiple team members.
  5. The finalists will be expected to demonstrate their working systems during the Symposium and attend the Awards Banquet. Two banquet tickets will be reimbursed per team, for one team member and the team mentor. Each team should bring all necessary equipment for the demonstration. The received power will be measured for the test scenarios using the same experimental setup. The Design Contest Judges will assess the final demonstrations and take into account the final reports to select the 1st, 2nd, and 3rd prize winners, who will receive certificates and cash prizes of US$1,500, $750 and $250, respectively. The prize winners will be announced at the Awards Banquet.
  6. After the Symposium, the finalists may revise their final reports for possible publication in the IEEE AP Magazine under the Education Column (the reports will be reviewed and must meet Magazine standards). Team mentors may either be listed as a co-author or acknowledged in the paper.
