CPW fed hexagonal micro strip fractal antenna for UWB wireless communications

A flower‐shaped ultra‐wideband fractal antenna is presented. It comprises a fourth iterative flower‐shaped radiator, asymmetrical stub‐loaded feeding line, and coplanar quarter elliptical ground planes. A wide operating band of 12.12 GHz (4.58‐16.7 GHz) for S 11 ≤ − 10 dB is achieved along with an overall antenna footprint of 15.7 × 11.4 mm2. In addition, other desirable characteristics, that is, omnidirectional radiation patterns, peak gain upto 5 dB, and fidelity factor more than 75% are achieved. A good agreement exists between the simulation and measured results. The obtained results illustrate that this antenna has wide operating range and compact dimensions than available structures.

A small size, planar and co‐planar waveguide fed metamaterial inspired antenna is proposed for ultra‐wideband (UWB) application. The main radiating element consists of three split‐ring resonators (SRR) and placed along one axis. Moreover, coplanar waveguide (CPW)‐fed line along with modified ground plane is used to improve the impedance matching. The physical size of proposed antenna is 25(W) × 22 (L) × 1.6 (H) mm3. The CPW‐fed metamaterial inspired antenna provides bandwidth of 10.4 GHz from 3.1 to 13.5 GHz based on the 3:1 (voltage standing wave ratio [VSWR] <2). Over the range of UWB frequency, peak realized gain varies from 2.5 to 4 dBi. The proposed antenna provides omnidrectional radiation patterns. Further, fidelity factor of the proposed antenna is also calculated and measured. The calculated fidelity factor is suitable for UWB applications. Finally, prototype of the antenna is developed and tested using network analyzer. The simulated and measured results are in good agreement.

“…The bow‐tie antenna has high bandwidth, good co‐polarization and low cross‐polarization but the large size increases the cost of manufacturing. The triangular slot antenna is easy to fabricate but it only covers the dual band structure 4‐8 GHz band making it unsuitable for UWB applications. The spline‐shaped structure and rotated slot is difficult to design and difficult to debug.…”

A miniaturized fractal antenna using Coplanar Wave Guide (CPW) fed and ultrawideband (UWB)‐artificial magnetic conductor (AMC) for ultra wideband and Active integrated application is designed and presented. This antenna covers frequency range from 2.5 to 10 GHz with ultrabandwidth of 7.5GHz and return loss well below −10 dB over the entire band of application. The antenna has an average gain of 3.35 dB without AMC and 7.7 dBi with UWB‐AMC. Physical dimension of the proposed antenna is (27 × 28 mm × 1.6) mm3 and for UWB‐AMC is (40 × 40 × 1.6) mm3. Complet set of UWB‐antenna and A.MC‐ is fabricated using FR.‐4 substrate with εr = 4.4, d = 0.0001and thickness (h) = 1.6 mm. Ansys HFSS Tool is used to analyze and optimize the parameters of antenna and UWB‐AMC. Vector Network Analyzer is used to validate the experimental result with simulation parameter of proposedantenna.
