“…The use of superstrate for AMC based AoC enhances the gain by 9.1 dB and radiation efficiency by 22.1 %. (f) The use of backside slots, reflector, and metal-strips in slots: In [102], three different methods have been utilized for a 60 GHz tapered slot Vivaldi AoC, fed by a double-Y balun, using 180 nm CMOS process. First, the addition of three rectangular slits on the back edge of Vivaldi AoC enhances the gain by 1.23 dBi and radiation efficiency by 1 %.…”

“…To study the loading effect of the metallic delay lens with different dimensions, simulations with lengths and widths of { (20,25), (25,30), (30,32), (35,34), (35,48)} (unit: mm) were carried out and the results show that the radiation improvement is not the best for cases with too large or too small a lens size. The |S 11 | and realized gain of three typical cases are compared in Figure 5b.…”

“…Another gain improvement technique for TSA is to use loading metallic structures, such as surface plasmon polaritons, metal patches or strips, and non-resonant artificial material, in the end-fire direction of the antenna to improve the radiation directivity in a quite broad band [30][31][32][33][34][35][36][37][38]. Typically, reference [30] reported a gain enhancement of 2 dB in the band of 22-27.5 GHz for an antipodal TSA loaded with spoof surface plasmon polaritons extending from the radiation aperture to the region beyond the antenna arms, and thus the proposed antenna was quite large in length.…”

“…In [31], an elliptical pseudo element patch and irregularly spaced notches were added to the TSA and realized high gains ranging from 4 dBi to a maximum of 16 dBi over a wideband of 2.5-57 GHz, with an antenna length of 186 mm. In [32][33][34], metal patches or strips array were added in the radiation direction as directors to improve the radiation of the TSA. Among them, the largest gain increase realized by optimized strips array reported in [34] was with a maximum gain increase of 3 dB from 4 to 6 GHz.…”

A post-wall-structured tapered slot antenna (PWTSA) loaded with an embedded metamaterial-based lens (metalens) is proposed and investigated for short-pulse applications. The proposed embedded metalens consists of not only a metallic delay lens, but also an airy acceleration region surrounding the lens, which is different from the conventional metalenses used in various tapered slot antennas and can exhibit a small equivalent permittivity. Therefore, the embedded metalens has a large usable range of permittivity and does not increase the size of the original prototype PWTSA. The post-wall structure and metalens of the proposed antenna can help it achieve a comprehensive and balanced performance, including a high fidelity, low cross-polarization, stable main-lobe direction and gain enhancement. The simulated and measured results show that without any increase in antenna size, the proposed antenna enhances the realized gain by 6.4 dB over the frequency range from 9 to 26 GHz and achieves a stable radiation with the offset of the main-lobe direction being confined to 2° up to 24.9 GHz. Furthermore, the cross-polarization levels are less than −20 dB and the fidelity is kept high for the short-pulse radiation with the frequency spectrum up to 30 GHz.

This paper presents a design of 60-GHz exponential tapered slot Vivaldi antenna-on-chip (AOC). The antenna is designed using standard 0.18µm six metal-layers CMOS technology. A double-Y balun feeding structure is used to make transition from coplanar waveguide to slot-line. Two techniques are investigated for improving antenna radiation properties. The first technique incorporates equal corrugations on the edges of exponential flaring section and other on the backed-edge of antenna to enhance the antenna gain. Second, a planar arc reflector is constructed using metal vias between M6 and M1 to inhibit the back lobe, contributing to the enhancement of gain and efficiency. The overall antenna size is compact and equal to 785µm×930µm. The influence of the antenna position on the radiation properties is also studied. The proposed antenna offers endfire radiation pattern with a simulated peak gain and a radiation efficiency of -0.4 dBi and 32%, respectively.
