“…In the above literature [15][16][17][18][19][20][21][22], the centre of attention has been set to improve the directional SIW H-plane horn's radiation performance. Further, some investigations have been done on the omnidirectional SIW Hplane horn antenna [23][24][25][26]. Omnidirectional SIW H-plane horn antennas described in [23][24]26] have exhibited low gain.…”

A compact substrate integrated folded waveguide (SIFW) H-plane horn antenna array with simultaneous omnidirectional and directional radiation characteristics for potential utilization to high-speed wireless communication is presented in this article. The realization of the proposed design has been accomplished by placing the apertures of nine exponentially tapered SIFW H-plane horns towards the circumference of a cylindrical substrate with an angular separation of 40 • between the horns. Every horn flaring includes a column of three slots. Centre probe feed technique has been used to excite the antenna. The radiation of the field by the horn apertures and through the slots of the horns flaring, respectively, results in an omnidirectional and a directional radiation pattern at 13.8 GHz and 18.42 GHz, with the gain of 7 dBi and 10.92 dBi. The proposed antenna has performed well and is in good agreement between simulation and measurement. The dimension of the antenna is 37.3 mm (diameter) × 1 mm (height) (1.71λ 0 × 0.046λ 0 at 13.8 GHz and 2.29λ 0 × 0.061λ 0 at 18.42 GHz). SIFW technology makes low profile antenna. The proposed design can be a promising option to be used as a low-profile antenna for high-speed wireless communication.

“…Further, some investigations have been done on the omnidirectional SIW Hplane horn antenna [23][24][25][26]. Omnidirectional SIW H-plane horn antennas described in [23][24]26] have exhibited low gain. Furthermore, in [24], quite low gain and bandwidth have been obtained despite the complex design.…”

“…Tapered slot antenna (TSA) is one of the best antennas used in ultra-wideband technology, which was first proposed by Hines et al in 1953 [4], and it is widely used in radio astronomy, ground penetrating radar, ultrawideband communication, ultra-wideband imaging and other fields [5][6][7]. TSA has the advantages of simple structure, easy processing and good port matching.…”

Abstract-In this paper, a novel bandwidth-enhanced ultra-wideband (UWB) tapered slot antenna, with Y-shaped corrugated edges, is proposed. In the double-slot structure, the two slots are separated by a V-shaped metal surface with straight edges, which is beneficial for improving the directivity of the antenna. Meanwhile, an exponential Y-shaped corrugated edge is designed. This novel corrugated edge not only can improve the impedance bandwidth of the antenna by extending the path of the current, but also can enhance the directivity by concentrating the energy near the tapered slot. The proposed antenna provides 167% fractional bandwidth from 2.5 GHz to 28 GHz. The gain of the antenna is more than 10 dB from 3.5 GHz to 25 GHz and more than 8 dB in the whole operating band.
