“…Though design does cover required applications effectively, it needs careful design to improve the impedance performance. A conductor‐backed (CB) ACS‐fed antenna is proposed in, 36 but it does cover WLAN frequency bands only. An ACS antenna with metamaterial structure (SRR/CSRR) is presented in Rajkumar and Kommur 37 to obtain a compact multiband performance.…”

“…However, it does cover only single frequency band. From the above literature survey, it is observed that most of the existing antenna designs have the following issues: large size, narrow bandwidth, gain, ka, and less coverage of applications 22–42 . To address the above issues, a compact antenna design with a rectangular‐shaped split‐ring resonator (RSRR) structure is discussed.…”

Summary In this paper, an electrically small inverted L‐shaped asymmetric coplanar strip‐fed antenna with a split‐ring resonator structure is proposed for multiband applications. It possesses an extended monopole antenna and a rectangular split‐ring resonator (RSRR) structure. A monopole is responsible for generating the first and last resonance frequencies. Similarly, the RSRR structure produces center frequency (5.5 GHz) among three resonance frequency bands and improves impedance matching at a higher frequency. The antenna has an electrical size of 0.176 λ0 × 0.096 λ0 × 0.012 λ0. The proposed antenna has a triband resonance response at 2.45, 5.5, and 7.5 GHz with a bandwidth of 560 MHz, 680 MHz, and 3 GHz, respectively, which covers WiBro (2.3 GHz), WLAN (2.4/5.2 GHz), WiMAX (2.5/5.5 GHz), X‐band downlink (7.4 GHz), and ITU band (8.5 GHz). The antenna design is simulated and validated with measured results and has better radiation characteristics in all the required frequency bands. The presence of metamaterial property in the proposed RSRR is analyzed. The design is an electrically small antenna, and it has a radian sphere (ka) = 0.64. Further, the proposed antenna performances are compared with the various existing literature.

A novel electromagnetically coupled circular patch antenna (CPA) with an eroded ground plane is proposed for the wireless local area network (WLAN) application. First, a simple CPA is designed for 2.4‐GHz WLAN band. At this frequency, the physical size of the CPA is large. Therefore, a CPA is designed at a higher frequency with much lesser dimensions, and some portion of the ground plane is eroded to observe the percentage of resonant frequency reduction. In order to avail the WLAN services at 2.4 GHz, a CPA is optimally designed at 5.76 GHz based on the same proportionality technique with an eroded ground plane. This miniaturized antenna resonates at 2.4 GHz frequency with excellent reflection and radiation characteristics. The simulation software ANSYS high‐frequency structure simulator is considered for the design of the proposed CPA. The CPA is physically fabricated and its characteristics are validated with the simulation result. It is also compared with some of the antennas available in the literature for the WLAN application. The comparative study shows that the proposed CPA is a miniaturized one with attractive performance parameters.

“…In [21], SRR was etched on the radiating element of an ACS-fed antenna for achieving WLAN/Worldwide Interoperability for Microwave Access (WiMAX) applications, but it does not cover the International Telecommunication Union (ITU) band. In [8][9][10][11][12][13][14][15][16] and [20,21], ACS-fed antenna designs cover either WLAN or WLAN/WiMAX or WLAN/ITU band. To cover the WLAN/WiMAX/ITU applications simultaneously, an additional antenna is required which increases the size of the overall system with additional cost.…”

Abstract-In this paper, a compact asymmetric coplanar strip (ACS)-fed mirrored L-shaped monopole antenna is presented. The proposed design consists of three mirrored L-shaped branches and a split ring resonator (SRR) loaded beneath the substrate, which are responsible for achieving multiband characteristics, compactness and good impedance matching. The proposed antenna with a compact dimension of 22 × 16.08 × 1.6 mm 3 is fabricated and tested. The experiment result indicates that the proposed design, having −10 dB impedance bandwidth of 200, 670 and 530 MHz for 2.44, 5.3 and 8.2 GHz, respectively, covers 2.4/5.2/5.8 GHz WLAN, 5.5 GHz WiMAX and 8.2 GHz ITU band. It has good radiation characteristics for both E-plane and H-plane in all the desired frequency bands and produces good performances compared to the existing antenna designs in the literature. The loaded SRR structure performance is validated through negative permeability extraction and various parametric studies.
