“…Apart from the traditional bow design, the antenna has bows with rectangular extensions, which results in the reduction of antenna dimensions and makes the antenna operate at lower frequency band. These bows are fed by a parallel tapered line having a feeding point patch (FPP) at the termination of SMA connector …”

“…These bows are fed by a parallel tapered line having a feeding point patch (FPP) at the termination of SMA connector. 23 A low cost FR4 substrate with thickness of 1.52 mm, dielectric constant of 4.4, and tangent loss of 0.02 is used for the mentioned design. Parametric studies are realized by HFSS in this study in order to perform a wideband antenna in GHz region with compact structure as much as possible.…”

In this article, a wideband printed bow‐tie antenna is designed entire band of GPS (L5), PCS, IMT‐2000, Bluetooth, Wi‐Fi, WiMAX bands, and the most of frequency range of UWB. Apart from the traditional designs, the proposed antenna includes tapered printed line with a feeding point patch and triangular bows with rectangular edge extensions, which makes the antenna more compact. The antenna realized at the frequency band of 1.49‐9.5 GHz (more than 6.3:1 ratio bandwidth) has the dimensions of 122 mm × 56 mm (0.61λ0 × 0.28λ0). According to measurement results, the realized gain varies between almost 1 and 6.5 dBi with 4.44 dBi average, which are in good agreement with simulation results. Radiation patterns at the lower frequencies of operating band show dipole like radiation pattern with higher cross‐pol discrimination levels while they degrade at the higher frequencies due to increase in gain.

“…Recently, a renewed interest has been demonstrated in flexible, highly-directive planar antennas [1][2][3][4][5][6][7][8][9][10]. With low profile and conformal configurations, these flexible antennas find numerous applications in emerging technologies such as sensor networks, internet of things (IoT), and wearable electronics [11].…”

“…Several research studies in recent past focussed on the design of LPDAs with stable broadband electromagnetic properties [6,8,9,[23][24][25][26][27]. The antennas were printed either on rigid substrates such as Arlon, Rogers, FR4 or on 1 mm thick PET substrates and hence cannot be considered for highly flexible electronics.…”

An eleven element log-periodic dipole-array (LPDA) antenna, occupying a surface area of only 90 × 52 mm 2 , printed on an ultra-thin flexible Kapton substrate of thickness 0.035 mm, is proposed. The antenna operates with a stricter 10 dB reflection coefficient bound in the frequency bands 2.75-3.53 GHz and 4-6.2 GHz. For a less stringent bound of 6 dB (which is acceptable for wearable applications), it operates in the wider range of 2.7-6.8 GHz. The antenna has an end-fire radiation pattern with a maximum measured gain of 6 dBi. The flexibility of the antenna is illustrated by reflection and radiation pattern measurements for three different radii, i.e., 50, 30, and 10 mm in both the convex and concave configurations. It is experimentally demonstrated that LPDA exhibits stable input-impedance characteristics and consistent radiation properties over the whole operating band under all bending conditions. The low cost, light weight, and flexible design, as well as the broadband performance in both concave and convex bent configurations, prove the suitability of the antenna for the contemporary flexible electronic devices.

“…This feeding technique presents some drawbacks such as the difficulty of soldering process and can deteriorate both the radiation pattern and the antenna matching. To overcome the shortcomings of this feeding technique, an ultrawideband planar LPDA antenna with mode converter balun is designed in [7] and an antenna is designed by introducing a subsectional tapered feed line instead of standard MSL feeding in [8]. However, these feeding techniques feed from head of the antenna.…”

A novel planar printed log-periodic dipole array (LPDA) antenna fed by tapered microstrip line (MSL) to double sided parallel strip line (DSPSL) is proposed in this paper. The proposed antenna adopts MSL feeding approach from backside. Using this feeding technique makes the printed LPDA antenna easier to be integrated into radio frequency (RF) circuits. In this paper, four layers are used to construct the antenna. The four layers of the printed LPDA antenna are printed on three thin dielectric substrates which are integrated together. To validate this approach, a printed LPDA antenna is simulated and fabricated for operating in the S and C bands (2.5-6 GHz). The antenna showed a good result over the whole frequency range with 2 : 1 VSWR, an average gain of 6.5 dB, and stable radiation patterns. The measured results are in very good agreement with simulations.
