Low-cost all-metal partially reflecting surface (AM PRS) based resonant-cavity antennas are presented in this paper. The AM PRSs are made by introducing square-shaped slots in a thin metallic sheet having moderate to high reflectivity ranging from -4.12 dB to -1.27 dB. An RCA designed using highly reflecting AM PRS has maximum directivity of 16.54 dBi and low 3 dB directivity bandwidth of 9.17% whereas those designed using less reflective AM PRSs have high directivity bandwidth but smaller peak directivity within the operating band.
