In this paper, we reveal a concept of low-profile Split Ring Resonator loaded metamaterial inspired antenna for Bluetooth/WiFi/WLAN/WiMAX communication systems. The antenna’s overall dimensions are 30 × 31 mm2 where two metamaterial unit cells are placed parallel to each other and a zig-zag feed line is connected with the SubMiniature version A connector. The defected ground technique was used to improve the antenna’s operational bandwidth. The computer simulation technology Microwave Studio was used to design and perform the numerical investigation, and the antenna was fabricated on FR-4 dielectric material. The Agilent N5227A VNA and anechoic chamber-based Satimo Star Lab were used to measure the antenna’s scattering parameters, voltage standing wave ratio, gain, efficiency and radiation patterns. The proposed metamaterial antenna had 200 MHz (2.40–2.60 GHz) and 390 MHz (3.40–3.79 GHz) overall bandwidth, which are similar to the simulated data. The measured results were applicable for Bluetooth (2.40–2.485 GHz), WiFi (2.4 GHz), WLAN (2.40–2.49 GHz and 3.65–3.69 GHz), and WiMAX (3.40–3.79 GHz) applications. The antenna’s average gain was 1.50 dBi, with the maximum and minimum gains of 2.25 dBi and 0.88 dBi, respectively, in addition to omnidirectional radiation patterns at operating bands.

“…In [1][2][3][4][5], dual-band antennas covering 2.4/5.2/5.8 GHz bands were proposed for wireless local area network (WLAN) applications. In [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], attempts were made to develop antennas for WLAN/WiMAX applications, including π-shaped slotted microstrip antennas with aperture-coupled feed [6], resonator antennas [7][8][9], dual and multipolarized antennas [10][11][12], magnetoelectric and magnetic dipole antennas [13,14], frequency-reconfigurable antennas using PIN-diode switch [15][16][17][18], metamaterial antennas [19][20][21], antennas with inverted-L-shaped radiating elements and parasitic elements in the ground plane [22], antennas with pentagonal ring slot fed at the vertex and E-slip with backfeeding [23], and antenna with bow-tie slot in a single metal sheet on top of the flexible substrate [24]. However, these antennas fail to cover the entire WLAN frequency band (2.4/5.2/5.8 GHz).…”

This research presents a triband compact printed antenna for WLAN and WiMAX applications. The antenna structure consists of a folded open stub, long and short L-shaped strips, and asymmetric trapezoid ground plane. Besides, it is of simple structure and operable in 2.4 GHz and 5 GHz (5.2/5.8 GHz) WLAN and 3.5/5.5 GHz WiMAX bands. The folded open stub and long and short L-shaped strips realize impedance matching at 2.4, 3.5, 5.2, and 5.8 GHz, and the asymmetric trapezoid ground plane fine-tunes impedance matching at 5.2, 5.5, and 5.8 GHz. In addition, the equivalent circuit model consolidated into lumped elements is also presented to explain its impedance matching characteristics. In this study, simulations were carried out, and a prototype antenna was fabricated and experimented. The simulation and experimental results are in good agreement. Specifically, the simulated and experimental radiation patterns are omnidirectional at 2.4, 3.5, and 5.2 GHz and near-omnidirectional at 5.5 and 5.8 GHz. Furthermore, the simulated and measured antenna gains are 1.269–3.074 dBi and 1.10–2.80 dBi, respectively. Essentially, the triband compact printed antenna covers 2.4 GHz and 5 GHz (5.2/5.8 GHz) WLAN and 3.5/5.5 GHz WiMAX frequency bands and thereby is a good candidate for WLAN/WiMAX applications.

This study presents an open‐ended triple‐band miniaturised metamaterial (MTM) inspired antenna based on the epsilon negative‐transmission line (ENG‐TL). The zeroth‐order resonance (ZOR) and first‐order resonance (FOR) characteristics are implemented using the ENG‐TL theory. The proposed MTM antenna consists of rectangular and square‐shaped complementary concentric closed ring resonator (CCCRR) in the left and right half of the asymmetric coplanar waveguide (CPW) ground plane, respectively. The CCCRR generates an extra coupling capacitance and inductance, which help for improving the gain at ZOR mode and better impedance matching at higher‐order mode. The resonance characteristic of the antenna is controlled by the shunt elements due to its open‐ended boundary condition. The proposed triple‐band MTM antenna offers measured −10 dB impedance bandwidths of 8.54% (1.12–1.22 GHz), 10.25% (2.22–2.46 GHz) and 35.75% (2.94–4.22 GHz). All these three bands show good impedance matching with appropriate gain and high radiation efficiency and also having an omnidirectional pattern in the xz‐plane and dipolar type pattern in the yz‐plane. The designed antenna shows an overall dimension of 0.11λ0 × 0.11λ0 × 0.006λ0 at ZOR frequency (1.16 GHz).
