Abstract. A novel slot antenna with RF-MEMS switches is proposed with two switches placed symmetrically on an asymmetrical meander-shaped slot yielding four different operating frequencies. A microstrip-fed meander slot antenna with copper tape acting as switches was manufactured as a prototype to test the concept. The measured results were satisfying for all four frequencies with a return loss well under –10 dB. Further use of additional switches on the same antenna is discussed in the paper.
