During the fourth module of the Electrical Engineering Bachelor, the project contains designing and building an antenna which can work at 433 MHz. Of course you make a simple design which will always work, but we wanted more. We decided to make a helical antenna. And not just one, but two! One little aspect of the helical antenna is that it should be very precise. This is where the DesignLab came to help.
The design was made and so the work could begin. Wood was cut by the laser cutter for preciseness. In the mechanical workshop, the ground plane was made using wood and mesh.
Our super awesome Dual Helical Antenna was finally finished and so the measuring could start. This is not that interesting, but it worked! Yeeeaahhh! The only detail is that it worked for 480 MHz instead of 433 MHz, but that are just details.
So what could have gone wrong? Probably the winding of the copper antenna since this is not done very carefully. Another option is that the design was not as perfect as we thought. Of course external factors could play a role as well.
Monday the 27th of June, the Great Antenna event will take place. This event is used to show the antennas of all groups, to see which group made the best antenna and to have a lot of fun. If anyone is curious, come by and see the best antenna made in the DesignLab: the Dual Helical Antenna!
