As I mentioned in the previous post, I will be using the concept of Meanderline antennas to try and optimise the design for the antenna. The antenna needs to be designed first, and then simulated in the design software before it can be manufactured and tested.
I have started using the software CST Microwave studio and have worked through an antenna design tutorial in order to learn how the software works and its capabilities. The design itself will just be meandering the copper tracks until the antenna is the correct length for the frequency required - in this case 20.1 MHz.
The design will also incorporate a ground plane underneath to prevent the antenna receiving signals reflected from the roof of the department.
While I am designing I will be simulating the design to check that the Scattering Parameters (s-parameters) show the antenna working at the frequency we expect it to. The radiation patterns will also be checked to ensure that the design is initially omnidirectional and that the ground plane is preventing signals from below reach the antenna.
