First Prototype of a Dense Dipole Array for MFAA
Submitter: | Pieter Benthem |
Description: | The first small prototype of a Dense Dipole Array (DDA) was manufactured and S-parameter measurements were done. The design consists of a 4x4 array of densely packed printed dipoles above a ground plane. Array elements are connected in parallel-pairs and fed differentially through a common-mode suppressing feed-board. Preliminary results of the measurements conducted so far have indicated a frequency range of 670-1643 MHz.
The work forms part of the PhD work of Jacki Gilmore from Stellenbosch University in collaboration with Astron through MIDPREP. The PCB manufacturing was done in-house by Albert van Duin and the mechanical design and manufacturing was organised by Raymond van den Brink. The measurements were done with the assistance of Michel Arts. Thank you all for your support! |
