“…We note that such a microstrip feeding line is selected to solve the problem of the beam tilt and gain decrease. This has been shown in [17] where a meandered microstrip feeding line was used for exciting two CSRR to obtain dual broadband performance. Therefore, out-of-phase currents are excited at a higher frequency band, which led to a great decrease of the broadside gain.…”

This paper proposes a new triple-band monopole antenna based on Complementary Split Ring Resonators (CSRR) perturbing the ground plane (GND). The antenna consists of an inverted-L-shaped monopole fed by a modified microstrip line with two CSRRs cut out of the ground plane. The operational bands are independently controlled by the CSRR unit cell parameters. In addition, the antenna presents a dual-polarization performance (vertical polarization at 2.4 GHz band and horizontal polarization at both 3.6 and 5.9 GHz bands). The designed antenna is fully planar and low profile avoiding the vias with the ground plane and covering the WLAN, WiMAX, and IEEE 801.11p bands at 2.45, 3.6, and 5.8 GHz. A compact prototype (0.32λ 0 × 0.32λ 0 being λ 0 is the wavelength corresponding to the lowest resonance frequency) has been fabricated and measured showing good agreement between simulations and measurements. The measured impedance bandwidths are 10% (2.38-2.63 GHz), 2.5% (3.54-3.63 GHz), and 20% (5.83-7.12 GHz) whereas the measured gains are 1.34, 0.68, and 2.65 dBi at 2.4, 3.6, and 5.9 GHz respectively.

“…However, etching the CSRR in the radiating element decreases both, gain and efficiency. The CSRRs can also be printed in the ground plane for multiband and broadband performances [17]. Additionally, SRRs and CSRRs have been widely used in the filtering antenna design in order to avoid interferences between adjacent bands [18]- [19].…”
