“…Many different configurations of wideband planar monopole configurations, such as rectangular, elliptical, triangular, and hexagonal, have been developed for ultrawideband (UWB) applications due to their low profile, ease of fabrication, and convenient integration with RF circuits [1][2][3][4][5][6][7]. One of the main challenges of the UWB monopole antennas is the instability of the antenna boresight gain over all the frequencies within the bandwidth.…”

International audienceThis article presents a composite right–left-handed (CLRH) zeroth-order resonator designed on a ferrite substrate. Numerical modelling and measurements of the device are presented. The proposed structure is realized in coplanar waveguide configuration using an interdigital capacitor and a shortcircuited stub inductor to add the left-handed property to the resonator. The ferrite substrate is magnetized in a direction perpendicular to the propagation direction. The tunable nature of the proposed device can be achieved by changing the applied magnetic bias. The resonator is designed to be tuned over the 3–5 GHz frequency band. Measured insertion loss is 5 dB giving interesting perspectives for the device. The length of the proposed device is 5.2 mm, which can be considered very small compared with a traditional half wave resonator

“…Zeroth order resonator has zero electric length and hence infinite guided wavelength at a certain finite microwave frequencies with very compact size [7]. The gap coupled approach has the advantages of harmonic suppression and size reduction [38][39][40][41]. They can be applied in filter applications [42][43][44][45].…”

The theoretical study and experimental results of a compact tunable left‐handed (LH) zeroth order metamaterial ferrite resonator is presented. The resonator has been designed and realised using a LH coplanar waveguide transmission line on a ferrite substrate. The theoretical analysis of the operation principles of the resonator has been provided. The detailed measurement setup and experimental results are discussed. The resonator is only 0.19 λg (65% reduced in size comparing with conventional one) at 4 GHz. The resonator has fractional bandwidth of 0.1% and average insertion loss, approximately 4.5 dB. Moreover, the zeroth order metamaterial ferrite resonator has tuning capability and requires lower DC magnetic bias.

“…The zeroth-order resonant antenna has a monopolar radiation pattern, which is similar to that of the traditional monopole antenna; thus, it is suitable for adoption on wireless devices requiring an omnidirectional radiation characteristic. Studies have presented zeroth-order resonant antennas based on microstrip technology [1][2][3][4][5][6][7][8][9] and a coplanar waveguide structure [10][11][12][13][14]. In those designs, the interdigital capacitator or the couple between the adjacent patches provided the left-handed series capacitance.…”

This paper proposes a compact zeroth-order resonant (ZOR) antenna with improved gain and efficiency. The proposed CRLH unit cell is based on the coplanar waveguide (CPW) structure. The proposed ZOR antenna is designed for a 2.45 GHz frequency band, and it has the characteristic of monopolar radiation. Shunt inductance is implemented by microstrip short-circuit stubs, and a metal-isolator-metal (MIM) capacitator provides series capacitance, where a large capacitance can be achieved in a small footprint. The proposed antenna comprises two interleaving composite right-/lefthanded CRLH unit cells, where the size of one unit cell is measured at only 0.12λ 0 × 0.098λ 0. Because the field is loosely confined within the CPW-based unit cell, a good antenna peak gain of 2.03 dBi, and a radiation efficiency of over 68% is achieved when fabricated on a thin substrate. The proposed antenna did not require an additional matching network, reducing the total antenna footprint. This paper presents antenna parameters such as the return loss, radiation pattern, antenna gain, and radiation efficiency to validate the proposed design, which achieved good simulation results.
