“…The antenna is designed with proper impedance matching with a 1.5 mm width of microstrip-fed transmission line inspired by half-cut radiator technology. Therefore, fewer deviations are achieved in all the results [23]. The comparative evaluation of the designed antenna is discussed in Table 1, revealing that the proposed antenna is compact in size and higher in bandwidth.…”

This paper presents a compact multiple input multiple output antenna (MIMO) with a wireless local area network (WLAN) notch characteristic for ultra-wideband (UWB) applications. The two modified rectangular radiators share a common ground that provides UWB response. The design is modeled over FR4 material and has an overall compact size of 0.34 λ0 × 0.24 λ0 × 0.015 λ0 mm3 at the frequency of 2.9 GHz. A tree-shaped decoupling structure with multiple slots in the ground is introduced between the ports to establish good isolation. The open-ended slots in the ground perturb diminish the surface current between two ports and ensure the isolation larger than 20 dB in the entire UWB from 2.9 GHz to 10.2 GHz. An S-shaped parasitic stub is utilized at the backside of the radiating element to implement a band notch characteristic from 5.03 GHz to 5.90 GHz. The proposed antenna is also investigated for wearable applications with a human tissue model showing a small SAR value (less than 1.6 W/kg). The simulated and measured result shows that the designed antenna suits MIMO performance and wearable devices.

A frequency reconfigurable 4‐port integrated ultra‐wideband and narrowband antenna structure for cognitive radio application is reported in this article. The proposed structure comprises four distinct antennas integrated on FR‐4 substrate of dimensions 42 × 42 × 1.6 mm. The first antenna, named as ANT‐1, is a CPW fed UWB antenna exhibiting −10 dB impedance bandwidth from 3 to 11 GHz, which includes the FCC unlicensed band ranging from 3.1 to 10.6 GHz. The remaining three antennas, named as ANT‐2, ANT‐3, and ANT‐4, respectively, are frequency reconfigurable narrowband antennas. Each narrowband antenna is incorporated with a varactor diode to obtain a fine frequency tuning. The first narrowband antenna (ANT‐2) covers a mid‐frequency band from 5.35 to 8.2 GHz. The second narrowband antenna (ANT‐3) attains a lower‐band from 3.1 to 5.375 GHz while the third narrowband antenna (ANT‐4) achieves an upper band ranging from 8 to 10.8 GHz. Simulated transmission coefficients are less than −16 dB between the antennas. ANT‐1, 2, 3, and 4 accomplish simulated maximum peak gains of 4.92, 3.4, 2.9, and 3.2 dBi, respectively. The proposed structure is fabricated to validate the simulation results. The measured reflection and transmission coefficient results are analyzed with the simulation results revealing a good matching.

Spiral-shaped UWB antennas, which are differ from each other in terms of feeding structure are presented in this manuscript. CPW and microstrip line feeding are used to excite the designed antenna to obtain different performance parameters. The overall physical dimensions of proposed antennas are 27 × 27 × 1.6 mm 3. These antennas are designed on low cost FR4 glass epoxy substrate with 1.6 mm thickness and dielectric constant 4.4. Impedance bandwidth (S 11 < −10 dB) obtained for measured CPW-fed antenna is 176.82% ranging (1.23-20.0 GHz) and microstrip line-fed antenna is 169% ranging (1.68-20.0 GHz). Various performance parameters of both the designed antennas are observed and calculated, such as, radiation pattern, gain, group delay, and radiation efficiency, which all are in the acceptable range for distinct UWB communication and other wireless standards. The optimized designed antennas are fabricated and tested for the validation of results and comparison among simulated and measured results of antennas have been made and found in good agreement with each other.
