Fork-shaped planar antenna for Bluetooth, WLAN, and WiMAX applications

In this article, wideband circularly polarized monopole antennas with multiresonating frequencies are presented for Bluetooth, WLAN, WiMAX, and X‐band applications. The designed antennas have dimensions of 50 × 35 × 1.6 mm3. Two different substrates (FR4‐epoxy and PTFE) are used for fabricating the antennas. The antennas consist of corner truncated I‐shaped and C‐shaped strips excited by a 50 Ω microstrip feed line. The parametric analyses are performed with the help of Ansoft HFSS V.11 EM simulator. Both antennas have been fabricated and measured. The measured percentage bandwidth of the antenna made by FR4 substrate is 31.32% (centered at 1.66 GHz), and 64.85% (centered at 5.69 GHz). The percentage bandwidth of antenna made by PTFE substrate is 20.57% (centered 2.43 GHz) and 68.74% (centered at 7.39 GHz). In addition to that, there exists 3 dB AR bandwidth for LHCP of about 1050 MHz for 5.2 GHz WLAN‐band. The reflection coefficient, radiation patterns, and the gains of both the antennas are studied in detail. It is found that the measured and simulated results are in good agreement.

Low-Profile Frequency Reconfigurable Antenna for Heterogeneous Wireless Systems

A low-profile (0.21λ g × 0.35λ g × 0.02λ g ) and a simply-structured frequency-switchable antenna with eight frequency choices is presented in this paper. The radiating structure (monopole) is printed on a 1.6-mm thicker, commercially-available substrate of FR-4 ( r = 4.4, tanδ = 0.020). Specifically, it uses three PIN diodes in the designated places to shift the resonant bands of the antenna. The antenna operates at four different modes depending on the ON and OFF states of the PIN diodes. While in each mode, the antenna covers two unique frequencies (Mode 1 = 1.8 and 3.29 GHz, Mode 2 = 2.23 and 3.9 GHz, Mode 3 = 2.4 and 4.55 GHz, and Mode 4 = 2.78 and 5.54 GHz). The performance results show that the proposed antenna scheme explores significant gain (>1.5 dBi in all modes) and reasonable efficiency (>82% in all modes) for each mode. Using a high-frequency structure simulator (HFSS), the switchable antenna is designed and optimized. The fabricated model along with the PIN diode and biasing network is tested experimentally to validate the simulation results. The proposed antenna may also be combined in compact and heterogeneous radio frequency (RF) front-ends because of its small geometry and efficient utilization of the frequency spectrum.

“…Because wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) technologies are the most widely used in wireless telecommunications devices requires multi-band antenna to fit multiple services in one device. The operating bands for these technologies as assigned by IEEE 802.11 are (WLAN: 2.4-2.484, 5.15-5.35 and 5.725-5.85 GHz) and (WiMAX: 2.5-2.69, 3.4-3.69 and 5.25-5.85 GHz) [1,3,[6][7][8]. GSM (900-1800 MHz), CDMA (870-890 MHz), PCS (1900 MHz), DCS (1710-1880 MHz), WLAN (2.45/5.8 GHz) and LTE-E/LTE-D (2300-2800 MHz) [9].…”

In this study, a monopole antenna based on C-shaped microstrip patch for multiband applications has been presented. The projected antenna uses FR-4 substrate and reduced ground plane (defected ground plane) with a compact size of 14 mm × 24 mm. Reception tools parameters have been encoded and inserted by means of CST electromagnetic software package. The simulation consequences of the proposed antenna in terms of S11 responses, gain and radiation patterns are appropriate for Wi MAX, C-band, and WLAN applications for recent communication systems.
