Research output: Contribution to journalJournal articleResearchpeer-review


The results of a parametric study for the development of an L-band, circularly polarised, dual-feed, cavity-backed annular slot antenna is presented. The study included detailed numerical simulations and measurements on a prototype with different ground planes, to assess the antenna’s applicability as an element in a small phased array antenna.
