“…In Ramzan and Topalli [30], the traditional square patch antenna size is reduced by 25% after incorporating CSRR in it. In Salhi et al [31], an active square-shaped CSRR is incorporated in a circular patch by using varicap diodes to design a tri-band antenna for wireless communication. Further, in Ref.…”

A miniaturized 2 x 1 multiple-input multiple-output (MIMO) antenna is presented in this paper. The designed antenna contains two circular patches with Complimentary Split-Ring Resonator (CSRR) that are etched in the ground which has a profound effect on antenna size reduction. It also helps in the reduction of isolation between two antennas. The maximum isolation between the two antennas is -84.62 dB at 2.8 GHz. The size of an antenna becomes more compact i.e., 40 x 20 x 1.6 mm3 after incorporating CSRR. The maximum gain of the designed antenna is 5.8 dBi at 4.3 GHz and the minimum reflection coefficient is -35.15 dB at 1.63 GHz. The operating band of an antenna is wide from 1.3 GHz to 4.3 GHz which covers Bluetooth, WiMax, and LTE applications. The proposed antenna is useful for various wireless applications.

In this article, a circular patch microstrip antenna with a metamaterial resonator for 4G applications is proposed. For the design of the circular antenna patch, an approximate calculation was performed. The circular resonator is inserted into the patch for some antennas, in different positions for a parametric study. When incorporating the resonator, the performance of the antenna is improved and analyzed through some parameters, when compared with the antenna without the resonator. To verify the influence of the resonator and validate its performance, simulated results were performed with the ANSYS HFSS ® software and compared with the experimental results, through prototypes, in which they showed a good agreement.

“…Due to the exciting properties of the wave interaction with metamaterials, various novel antennas with desired properties have been inspired: compact [1][2][3], high-gain [2,4], broadband [4], multi-band [5], frequencyscanning [6], or even those with combined characteristics [2,4,7] and interdisciplinary functions [8] have been reported. A comprehensive review on the recent progresses on metamaterial-inspired antennas is given in [9].…”

The Complimentary Split Ring Resonator (CSRR) is now popular in microwave devices. However, the analytical interpretations of its resonance frequencies, especially that with finite grounds, remains elusive. We demonstrate in this letter a novel method of unveiling the resonance mechanisms of antennas loaded with a finite-grounded CSRR (FG-CSRR) based on the equivalent circuit models. As a proof-of-concept, a triple-band antenna with FG-CSRR structure is explored, whose inner patch is loaded with additional elements with negligible impact on the inherent resonances of FG-CSRR. Various FG-CSRR-loaded antennas with different parameters are furthermore applied to validate our method. The proposed analytical model would facilitate the design of the operating mechanism of these antennas. Moreover, less metallic coating and the independent resonances of FG-CSRR promise its suitability for miniaturized microwave systems.
