“…For these applications, conformal antennas need to cover a wide bandwidth and have end-fire radiation beam. A variety of conformal antennas have been investigated during the past two decades, including monopole antennas [7,8], slot antennas [9,10], microstrip antenna arrays [11][12][13], log-periodic antennas [14], balanced antipodal Vivaldi antenna [15], and substrate integrated waveguide (SIW) antennas [16,17]. However, most of these antennas are mounted on metallic surfaces and have broadside radiation beam.…”

The characteristics of a novel antipodal Vivaldi antenna array mounted on a dielectric cone are presented. By employing antipodal Vivaldi antenna element, the antenna array shows ultrawide bandwidth and end-fire radiation characteristics. Our simulations show that the cone curvature has an obvious influence on the performance of the conformal antenna, in terms of both the bandwidth and the radiation patterns. The thickness and permittivity of the dielectric cone have an effect on the bandwidth of the conformal antenna. Measurement results of both single antenna and conformal antenna array show a good agreement with the simulated results. The measured conformal antenna can achieve a −10 dBS11with bandwidth of 2.2–12 GHz and demonstrate a typical end-fire radiation beam. These findings provide useful guidelines and insights for the design of wideband end-fire antennas mounted on a dielectric cone.

“…A tapered slot antenna (TSA) is a planar traveling-wave antenna with end-fire radiation that gives good directivity and gain, good cross-polarization, wide bandwidth, and easy construction. This antenna was first introduced by Gibson [1], by which it was also known as the Vivaldi antenna, and many improvements to the initial design have been proposed since its introduction [2–8]. In [2, 3], a dual exponential TSA (DETSA) and dual V-type linear TSA (DVLTSA) were investigated.…”

In this paper, a miniaturized CPW-fed tapered slot antenna (TSA) with a modified CPW to slot-line transition structure was introduced. An air-bridge and tapered slot edge (TSE) structure was also employed to broaden the transition bandwidth. Through these applied modifications, negative features of the original TSA (limitation of transition) and antipodal Vivaldi antenna (bad cross-polarization) are both removed, while all the positive features remained. Results showed that the proposed structure offered a broad bandwidth of 2.6–20 GHz and also exhibited an appropriate current distribution with high radiation efficiency. The radiation pattern was stable in the working frequency band with good directivity, gain, and low cross-polarization. The proposed antenna structure also presented satisfactory time-domain characteristics. In this study, we confirmed the simulation results through data measurements.
