“…ACS method has a single ground plane instead of double ground planes as in the coplanar waveguide (CPW) fed technique, and it possesses all the advantages of the CPW technique. These features make ACS-fed antenna method suitable for easy integration and better size reduction process [7]. Various ACS-fed antenna techniques have been proposed to achieve the multiband characteristics [8][9][10][11][12][13][14][15][16].…”

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.

“…However, integration of these antennas with RF-MIC circuits with limited access to only service in WiMAX/WLAN frequency bands is a difficult task. Asymmetrical coplanar strip (ACS) feed multiband antennas provide easy integration solutions with RF-MIC have been reported in [11][12][13][14][15][16][17]. In general, an ACS feed antenna provides about 50% size reduction compared to the traditional CPW feed antenna as only one half the ground plane of the CPW structure is considered [16].…”

Abstract-In this article, the design and analysis of a compact asymmetrical coplanar strip (ACS) feed multiband monopole antenna operating over the frequency range of Bluetooth/IMT-E (2.4-2.484/2.5-2.6 GHz), worldwide interoperability for microwave access (WiMAX: 3.3-3.6 GHz) and wireless local area network (WLAN: 5.15-5.825 GHz) for Personal Wireless Communication Systems (PWCS) applications has been investigated. The proposed antenna consists of a semi-circular arc and L-shaped stub which forms a vertically flipped G structure that facilitates the multi-band operation at 2.4 GHz and 3.5/5.5 GHz respectively. The antenna is fabricated on a low cost FR-4 substrate having thickness of 1 mm and has compact dimensions of 24 × 10 mm 2 . The proposed antenna yields a highly isolated measured impedance bandwidth of 2.3-2.7 GHz, 3.25-3.65 GHz and 5.1-6 GHz for Bluetooth/IMT-E, WiMAX and WLAN bands respectively and exhibits symmetrical radiation pattern, stable gain across all operating frequency bands which makes the antenna a suitable candidate for PWCS applications.

“…Hence, it is highly desirable to design a multiband antenna which can meet both the WLAN and WiMAX bands. Therefore, different types of multiband antennas have been proposed to cater the multiband requirement, such as [4][5][6][7][8][9]. For example, a tri-band monopole antenna with double coupled C-shaped strips for WLAN/WiMAX applications is presented [4], open L-slot antenna with a slit and a strip for WLAN/WiMAX triband operation [5,6] presented a tri-band design of a circular slot patch antenna for WLAN/WiMAX applications.…”

“…In order to further minimize the overall size of antennas, literature [9] presented an effective feeding (asymmetric coplanar strip (ACS) feeding) technique. Unlike the traditional antennas using a larger ground plane or a coaxial line feed, the ACS-fed structure only has half a ground plane.…”

“…The asymmetric coplanar strip feed used here has all the advantages of a uniplanar feed along with compactness, and the feeding mechanism can be analogized to the coplanar wave guide feed. However, the proposed antenna in [9] still has a large size and only covers one band, namely for WLAN applications. Another ACS-fed dual-band antenna for 2.4/5.8 GHz WLAN applications has been studied in [10], the proposed antenna uses loaded capacitance terminations to reduce the size, but it has a complex structure and is hard to design.…”

Abstract-In this paper, a compact asymmetric coplanar strip (ACS)-fed printed monopole antenna for tri-band WLAN/WiMAX applications is presented. The proposed antenna is composed of a circulararc-shaped stepped monopole with dual operating frequencies at 2.4/5.7 GHz and a simple circular-arcshaped strip with the third operating frequency at 3.5 GHz. The three resonant frequencies of the antenna can be controlled by adjusting the geometries and the sizes of the stepped monopole, the strip and the ground plane. The antenna occupies a very compact size of 22.1 × 12 mm 2 including the ground plane, has nearly omnidirectional radiation characteristics and reasonable gain in the operating bands. The simple feeding structure, compactness and uniplanar design make it easy to be integrated within the portable device for wireless communications.
