A novel uniplanar broadband antenna using the coplanar stripline (CPS) and the epsilon negative transmission line (ENG TL) is presented in this article. By using CPS as the feeding structure, the antenna becomes more compact in the transverse direction and the uniplanar structure makes it easier to integrate with other microwave components. By integrating ENG TL on the antenna, the zeroth‐, first‐, and second positive‐order resonant modes located at 3.50 GHz, 5.72 GHz, and 6.57 GHz, respectively, have appeared. The bandwidth enhancement is achieved due to that the three resonant modes of the ENG TL are merged into a wideband with good impedance matching. Simulation and measured results have shown that the bandwidth of the proposed antenna is increased from 1.95 GHz (4.58 GHz ∼ 6.53 GHz) to 3.47 GHz (3.26 GHz ∼ 6.73 GHz) compared with its unloaded counterpart.

“…In Ref. , a bisected miniaturized ZOR antenna combing the CPS and the TL MTM is proposed, the antenna is very compact with dimensions of 0.11 λ g × 0.18 λ g , however, the bandwidth is still too narrow with 6.1%. As can be seen, how to realize miniaturized and broadband antenna with TL MTM is still a challenge for the researchers.…”

“…Numerous work on compact antennas have been reported in last decade with metamaterial (MTM) approach due to the exclusive properties like negative refractive index and antiparallel phase and group velocities . Enhanced bandwidth, compact size and high radiation efficiency were reported by most of the researcher groups using MTM structures . A special case of MTM theory, zeroth order resonance (ZOR) provides a theoretical concept to miniaturize antennas .…”

A miniaturized dual‐band metamaterial (MTM) antenna has been designed in this article. The designed coplanar waveguide fed antenna has composed of inner split‐ring resonator and an outer open ring resonator with rectangular stub. The series parameter of the antenna is used to determine the zeroth order resonance frequency due to short‐ended boundary condition. The whole size of proposed structure is 20 × 25.5 mm2. This MTM antenna exhibits dual‐band operation at 3.17 GHz (3.1–3.22 GHz) and 5.39 GHz (5.27–5.47 GHz). The proposed MTM structure achieves measured peak gain of 0.71 and 1.89 dB at 3.17 and 5.39 GHz, respectively. The proposed antenna can be used for recent radio communication in form of S‐band application and Wi‐MAX.

“…However, ZOR antennas suffer from narrow bandwidth and low radiation efficiency [2][3][4][5]. Various ZOR antennas with enhanced bandwidth and efficiency have been proposed in [6][7][8][9][10][11][12]. In [8] the bandwidth was improved up to 67.4% by merging first order resonance to the ZOR antenna, and an efficiency of 90.08% was achieved.…”

Abstract-A low-profile bandwidth-enhanced zeroth-order resonant (ZOR) antenna based on composite right/left-handed transmission line (CRLH-TL) theory loaded by parasitic element is presented in this paper. The bandwidth and efficiency of the proposed ZOR antenna is improved simultaneously by introducing a parasitic element resonating within the CRLH-TL band-stop. The dispersive behavior of the ZOR antenna is analyzed by performing full-wave simulation using CST microwave studio and compared with the theoretical circuit model. The overall dimensions of the proposed antenna is 0.303λ 0 × 0.248λ 0 × 0.003λ 0 . The antenna has been fabricated and tested. The experimental results exhibit wide operational bandwidth of 87.1% and excellent radiation efficiency up to 95.7%. Owing to the symmetrical configuration of the proposed design the polarization purity better than −14 dB is obtained. The measured results are in very good agreement with the simulation. The compact, uni-planar and via-less configuration of the proposed antenna with reasonable polarization purity makes it desirable to be used for modern wireless communication systems such as GSM, UMTS, WiMAX, WLAN and LTE.
