A Compact Broadband and High Gain Tapered Slot Antenna with Stripline Feeding Network for H, X, Ku and K Band Applications

Abstract

In this paper, a planar travelling wave tapered slot antenna with compact size is proposed for wireless communication applications. The prototype of antenna is developed on Roger RT/Duroid 5880 laminate with tan δ = 0.0009, a relative permittivity of 2.2 while working in the range of 6GHz-21GHz. The simple feeding technique transits with radial cavity and the opening taper profile. The antenna dimensions of the antenna have been designed in such a manner so as to enable impedance matching. The parametric study of the variables is carried out by various scrupulous simulations. The designed characteristic antenna has achieved an impedance bandwidth in the broadband spectrum of 111.11% at the minimum 10-dB return loss and peak realized gain of 7dBi is obtained for a resonant frequency of 19.6GHz. The simulated results are in good agreement with experimental results and hence make the antenna suitable for H (6-8 GHz), X (8-12 GHz), Ku (12-18 GHz) and K (18-26 GHz) and future wireless communication applications.

A New CPW-Fed Semicircular Inverted Triangular Shaped Antenna Based on Mixed-Alternate Approach for 5G Millimeter-Wave Wireless Applications

“…In the past five years, researchers have proposed various strategies and have modified slot antenna designs to attain broad impedance bandwidth and high gain features. These approaches have mainly focused on different feeding networks [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ], defected ground structures (DGS) [ 22 , 23 , 24 ], artificial magnetic conductors (AMC) loaded lattice [ 25 ] and the etching of cut slits from radiators [ 26 , 27 , 28 , 29 ]. However, few of these compact and low profile antenna design structures were capable of covering a broad bandwidth at 5G mm-Wave frequency range.…”

A Miniaturized Broadband and High Gain Planar Vivaldi Antenna for Future Wireless Communication Applications

“…However, very few antenna designs have a compact size with a tapered profile and can attain the antenna's optimal key characteristics. In the literature, various antenna geometries, such as slits, tapered slot radiator, and flared transition with modified cavity stubs [14][15][16][17] have been reported. Also, several designs based on different slot shapes [18][19][20] were suggested to achieve the required gain, acceptable BW, radiation efficiency, and perfect impedance matching.…”
