“…Numerous AMC structures have been explored to date in order to improve the radiation efficiency and bandwidth of on-chip antennas [10][11][12][13] , which includes proton implantation and micromachining 14,15 . These AMC structures require complex manufacturing steps and hence are highly expensive for mass production.…”

this paper presents a novel on-chip antenna using standard cMoS-technology based on metasurface implemented on two-layers polyimide substrates with a thickness of 500 μm. the aluminium groundplane with thickness of 3 μm is sandwiched between the two-layers. concentric dielectric-rings are etched in the ground-plane under the radiation patches implemented on the top-layer. the radiation patches comprise concentric metal-rings that are arranged in a 3 × 3 matrix. The antennas are excited by coupling electromagnetic energy through the gaps of the concentric dielectric-rings in the groundplane using a microstrip feedline created on the bottom polyimide-layer. the open-ended feedline is split in three-branches that are aligned under the radiation elements to couple the maximum energy. in this structure, the concentric metal-rings essentially act as series left-handed capacitances C L that extend the effective aperture area of the antenna without affecting its dimensions, and the concentric dielectric rings etched in the ground-plane act as shunt left-handed inductors L L , which suppress the surface-waves and reduce the substrates losses that leads to improved bandwidth and radiation properties. The overall structure behaves like a metasurface that is shown to exhibit a very large bandwidth of 0.350-0.385 THz with an average radiation gain and efficiency of 8.15dBi and 65.71%, respectively. It has dimensions of 6 × 6 × 1 mm 3 that makes it suitable for on-chip implementation.Antenna is the key component to enable wireless communication however their physical size is a function of the operating frequency. Applications of on-chip antennas is therefore limited to high-frequencies due to the large size of antenna at lower frequencies. Off chip antennas however offer the benefit of radiation efficiency as they can be implemented on low-loss dielectric substrates 1-6 ..Currently, antennas for front-end transceivers can be realised using three different methods, which include: (i) Antenna-in-Package (AiP), where the antenna is embedded in the IC's packaging; (ii) Antenna-on-Chip (AoC), where the antenna is realized on substrate; and (iii) this is a hybrid of AoC and AiP, where the radiating element is realized off-chip. Wire bonding and flip chip are the two commonly used interconnections techniques employed in AiP to connect the die and the antenna 7 . These types of interconnects are highly lossy at high frequencies due to impedance mismatch. The only viable solution to overcome this loss is by using on-chip antenna, which should significantly reduce the manufacturing cost of system-on-chip (SoC).The development of a truly efficient cost effective on-chip antenna is a challenging endeavour. The main challenges are attributed to (1) low resistivity of dielectric substrates, which is approximately 10 ohm-cm, contributes to substrate loss of 85% whereas metallization loss is only 15%; (2) high permittivity substrate confines most of the electromagnetic energy in the substrate rather than being radiated into free-space, which ...

“…In the 60 GHz band, the proposed DML antenna indicated a comparable gain with Huang et al and Wang and Sun [19,28] with larger bandwidth and achieved multiband of operation. While Khan et al and Song et al [29,30] had lower gain and single band of operation at frequency higher than the proposed antenna, both antennas had the same efficiency (35%) at 65 GHz range.…”

A new, compact, on-chip antenna architecture for 5G body-centric networks’ (BCNs) applications is presented in this paper. The integrated antenna combines two turns of dual-meander lines (DML) on two stacked layers and a metal ground layer. The proposed DML antenna structure operated at resonant bands 22 GHz, 34 GHz, 44 GHz, and 58 GHz with an operating bandwidth up to 2 GHz at impedance bandwidth ≤−7.5 dB (VSWR—Voltage Standing Wave Ratio ≤ 2.5) and antenna gain about −20 dBi, −15 dBi, −10 dBi, and −1 dBi, respectively. Then it was compared with conventional single-meander line antenna. The proposed structure decreased the resonant frequency by 22%, increased number of tuning bands, and broadened the operating bandwidth by 25%, 15%, 10%, and 20% for the tuning bands to be a suitable choice for high-data -ate biomedical applications. Furthermore, the proposed antenna was simulated and studied for its performance on and inside the human body to test the integration effect in wearable equipment. The results showed that the antenna had acceptable performance in both locations. All simulations of the proposed antenna were done were done by using Ansys HFSS (high-frequency structure simulator) v.15 (Ansys, Canonsburg, PA, USA). The DML (Digital Microwave Links) antenna was fabricated by using UMC (United Microelectronics Corporation) 180 nm CMOS (Complementary Metal–Oxidesemi–Conductor) technology with a total area of 1150 µm × 200 µm and the results showed a good agreement between measured and simulated results.

A double-rhomboid bowtie-slot on-chip antenna aided by a back-to-back E-shaped electromagnetic band-gap surface for gain enhancement at W-band is presented. The specific structure of both, the antenna and the EBG surface is being reported for the first time in an on-chip implementation. The antenna is analyzed independently as well as backed by different electromagnetic band-gap reflective surfaces using standard 0.13 µm BiCMOS process. The proposed EBG surface provides a measured gain enhancement of 2 dB and 8 dB when used as a frequency selective surface and as an articial magnetic conductor, respectively. With an overall chip-size of 1×1 mm 2 , the on-chip antenna demonstrates a-6 dB impedance bandwidth from 75-100 GHz and an effective gain bandwidth from 80-90 GHz with a peak measured gain of-0.58 dBi at 84 GHz. The antenna has the smallest reported size and the highest gain in W-Band with artificial magnetic conductor as reflective surface.
