Compact triple-frequency antenna for sub GHz wireless communications
free download

The design of a compact printed antenna operating concurrently at three distinct frequencies is presented for sub GHz wireless communications. The radiation properties of the antenna, realized by using a low-cost PCB process on FR4 substrate, have been measured and the A novel compact wearable antenna printed on paper is presented. The antenna comprises a non-resonant coplanar monopole antenna placed on a miniaturized AMC (total size of 0.14 λ0 x 0.14 λ0 x 0.01 λ0 at 700 MHz). The manufacturing process only requires a commercial
