Abstract :
Two compact triple-band monopole antennas consisting of a single-loop resonator (SLR) fed with coplanar waveguide (CPW) and microstrip transmission lines, respectively, are proposed. The SLR exhibiting three resonances is used to achieve the three operating frequency bands ranging from 2.4 to 6 GHz. The proposed triple-band antennas exhibit very well eight-like radiation patterns and low cross-polarisations, which have potential applications for wireless communications.
