“…An infinite balun was realized by soldering the outer mesh of the coaxial cable to the lower transmission line feeding the dipoles, and the inner conductor of the coaxial cable was connected to the upper central feed line via a hole drilled in the substrate. This infinite balun [14] does the unbalanced to balanced impedance transformation which is required to reduce the current flowing on the outer shield of the coaxial cable. As this infinite balun, together with the solder joints, was difficult to model in Ansoft HFSS, a differential port was placed at the shorter dipole side.…”

In this paper, a printed split ring resonator (SRR) loaded log-periodic Koch dipole antenna (SLPKDA) is proposed. Koch-shaped dipoles when being loaded with split ring resonator (SRR) yielded a compact antenna, still preserving the radiation properties of log-periodic dipole antenna (LPDA). Measurement results show that the proposed antenna has a wide bandwidth, good impedance match and gain of 4 dBi over the band of frequencies from 0.9 GHz to 2.5 GHz. Both vertical and horizontal dimension reductions are achieved by loading Koch dipoles with SRR.

A compact wide band Printed LPDA (Log Periodic Dipole Array) antenna is proposed for WLAN applications in 5-6 GHz range. The antenna having dimensions of 36.58 mm x 24.37 mm x1.6 mm is designed and simulated using HFSS 13. The prototype of proposed antenna is developed using simple FR4 substrate. The proposed antenna works well in the desired operating bandwidth from 5-6 GHz and covers dual bands of IEEE 802.11a (5.15-5.35 GHz and 5.725-5.825 GHz) with VSWR effectively less than 2. The antenna shows a wide impedance bandwidth of 1.643 GHz from 4.869 GHz -6.512 GHz, with bandwidth efficiency of 28.87 %. The antenna gain is > 6 dB throughout the operating band, with max gain of 7.6 dB at 5.6 GHz and stable radiation pattern in end fire direction. Measured results for S 11 parameter are in good agreement with simulated one, which validates the proposed antenna design.

“…Though LPDA are usually employed as broadband antennas [10,11,12], we select here the LPDA configuration for dual band operation, exploiting the same idea as in [5], but using a cost-effective PET substrate and a different layout, based on a GCPW, which allows a fully planar realization [13].…”

A dual-band printed Log-periodic dipole array (LPDA) antenna for wireless communications, designed on a lowcost PET substrate and implemented by inkjet-printing conductive ink, is presented. The proposed antenna can be used for wireless communications both within the UHF (2.4-2.484 GHz) and SHF (5.2-5.8 GHz) wireless frequency bands, and presents a good out-of-band rejection, without the need of stopband filters. The antenna has been designed using a general purpose 3D CAD, CST Microwave Studio, and then realized. Measured results are in very good agreement with simulations.
