Hi folks, We are looking for for an antenna for 70 cm with no moving parts on a cubesat face. So I'm thinking of a microstrip patch antenna. Online calculations requires blocks greater than 10 * 10cm, so I am thinking of a short microstrip stub to match to a 10 x 7.5 cm patch on FR4 pcb double-sided with a groundplane underneath.
Any thoughts and advice gratefully received! Callsign <at> amsat Dot org
