“…Similarly, a CPW fed and microstrip fed slotted bow-tie antenna for tri-band applications were presented in [15,16], respectively. A CPW fed slotted bow-tie antenna was proposed in [17], where the bandwidth was enhanced up to 54% at the centre frequency of 6.4 GHz by modifying its edge of the bow-tie shape. A quasi-selfcomplimentary bow-tie antenna with a CPW feed impedance matching technique was proposed for UWB operation [18].…”

“…From the analysis of above literature, it is evident that ample research on different bow-tie configurations and using CPW feeding has already been carried out due to their inherent features. However, these bow-tie antenna designs are primarily based on double sided structure [9][10][11], slotted configuration [13][14][15][16][17][19][20][21] and quasi-self-complementary type [18]. The main challenges associated with most of these configurations which increase the design complexity are requirement of microstrip to CPW transition, microstrip to parallel strip transition and wideband matching balun [12,13,22,23] and so on.…”

A compact coplanar waveguide (CPW) fed frequency reconfigurable bow‐tie microstrip antenna is proposed and experimentally verified which can be tuned at different bands between 1.94 and 3.27 GHz in single‐band and dual‐band modes. Two slots are carefully introduced on the ground plane of the antenna where two active varactor diodes are placed to vary its fundamental mode of radiation by variation of capacitance. To validate the antenna design, a fully functional prototype is fabricated and measured which ensures that the device can be operated at different frequencies of 2.02, 2.19 and 2.37 GHz with 35.9, 30.8 and 24.6% of impedance bandwidth, respectively, in the single‐band mode. In dual‐band reconfigurability mode, the resonant frequency of the antenna can be varied at 2.08, 2.17 and 2.3 GHz with a higher mode band within 2.7 and 3.3 GHz. The antenna shows maximum gain of 1.33 dB with 96.9% efficiency and 1.5 dB with 95.4% efficiency for single‐band and dual‐band reconfigurability mode, respectively. More importantly, the antenna has a compact dimension (0.31λ×0.32λ×0.0103λ at 1.94 GHz) and it produces symmetrical monopole type radiation pattern at all tunable bands.

“…In past studies, researchers tried to enhance the key performance parameters of the CPA by incorporating the various approaches [5][6][7][8]. Besides, several designs based on different shapes of slots [9][10][11][12], radiators [13][14][15][16], and ground plane [17,18] have been proposed to attain the substantial peak realized gain, good radiation efficiency, and acceptable impedance BW along with perfect matching performance. e investigated antennas have complex designs and analyzed results were optimal with a trade-off between the BW, peak gain, radiation efficiency, and compact dimensions.…”

This paper presents a new design of a compact, high-gain coplanar waveguide-fed antenna and proposes a multielement approach to attain enhanced characteristics. The proposed method overcomes the simulation and geometrical complexity and achieves optimal performance features. The antenna prototype is carefully designed, and simulation results have been analyzed. The proposed antenna was fabricated on a new WangLing TP-2 laminate with dimensions (0.195λ × 0.163λ × 0.0052λ) at the lowest resonance of 9.78 GHz. The results have been tested and experimentally verified. The antenna model achieved excellent performance including a peak realized gain better than 9.0 dBi, optimal radiation efficiency better than 87.6% over the operating band, and a good relative bandwidth of 11.48% at 10 dB return loss. Symmetrical stable far-field radiation pattern in orthogonal planes and strong distribution of current are observed. Moreover, a comparative analysis with state-of-the-artwork is presented. The measured and simulation result shows a good agreement. The high-performance antenna results reveal that the proposed model is a good contender of military airborne, land, and naval radar applications.

“…The bow‐tie antenna fed by an asymmetric coplanar wave guide with different slot lengths has widened the operation bandwidth, but the peak gain is only about 5.53 dBi . Using the modified aperture, a Coplanar waveguide‐fed bow‐tie dipole has achieved a peak gain of about 7.71 dBi, while the measured IBW is not wide enough (IBW of 54%) . A novel bow‐tie antenna fabricated on a flexible substrate reports an IBW of 57.7%, which is suitable for WLAN/WiMax systems .…”

A novel broadband bow-tie antenna with high-gain performance throughout the operating band is proposed and investigated in this article. This folded sectorial bow-tie antenna is fed by a Г-shaped strip balun, and the electromagnetic coupling feed mechanism is easy to optimize the impedance matching. The study of proposed antenna performance with different geometric parameters has been conducted. The final design is fabricated and measured, and the results exhibit a good impedance bandwidth of approximately 93.3% for VSWR≤2 ranging from 1.35 to 3.71 GHz, stable gain of 8.43-10.02 dBi, and unidirectional radiation patterns over the whole operating band. Broadband coverage, stable high-gain performance, and the simple structure make this antenna an excellent candidate for wireless communication systems.
