Short vertical built for one frequency

Hi, and thank you in advance for taking a look at this post. I've come a long way since my first post, but still learning a ton. I'm not great with antenna theory, and haven't been able to locate information about my question.

Scenario: a friend and I each have a 40m Pixie radio set for 7.023 - 7.026mhz. We are both General class, and want to work in the 7.026 frequency to practice our CW code. We will be on a university campus, and sometimes in the same building. We should like an extra short antenna for these.

I know there are shorty stub antennas manufactured for other bands. But I don't fully understand the theory behind it. Essentially we would want to build a short antenna that is resonant at 7.026 and only that frequency. I am assuming that since we don't need to cover and entire band, this would make this possible.

Anyone have information, websites, or plans to make this happen? We have access to a wireless engineering lab on campus, and will be able to fully test the antennas before using them.

This classic article by Jerry W2FMI has very useful experimental data for designing short vertical antennas.
