Samenvatting

This paper presents the design and analysis of an on-rocket antenna used in a radio-interferometry experiment. The goal of the experiment is to accurately track a sounding rocket during flight. The antenna operates in the 70 cm band and is designed to work under tight constraints; a confined space, stable center frequency under large temperature variations and low budget. A microstrip patch antenna on PEEK450G903 substrate was identified as the most suitable solution, due to the relatively low cost and temperature stable dielectric properties of the PEEK material. This antenna design achieved a bandwidth of 2.5 MHz. Measurements were performed on the antenna before and after flight such that changes in performance due to vibrations, temperature and other environmental conditions can be evaluated.
