“…The normalized 2D radiation pattern of the proposed antenna with and without the presence of the human body at two main coordinates, ϕ = 90 • and θ = 90 • , were compared at different resonant frequencies, as shown in Table 1. In references Huang et al and Cao et al [19,27], antennas resonated at 24 GHz but with narrow bandwidth and a larger area than the proposed antenna. The proposed antenna has low antenna gain at lower frequency; this can be explained due to the small area which reduces the aperture area of the antenna.…”

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 new compact 24-GHz ladder reflector antenna on chip has been developed using the standard 0.18-um six metal layers complementary metal-oxide-semiconductor (CMOS) process. The antenna consists of an active dipole and a ladder reflector array. The ladder reflector array successfully adjusts the radiation direction of the active dipole and effectively suppresses the active dipole interference to chip circuit. The measured results show that the ladder reflector antenna has a 6.25-dBdc gain at 24 GHz and a 6-dB 11 impedance bandwidth of 19.92-27.60 GHz. The design method presented in this letter is quite straightforward, and can be used to develop antenna on chip for the wireless interconnect for interchip communications. Index Terms-Antenna gain, antenna on chip (AOC), directivity, interchip communications, wireless interconnect.

“…For this purpose, mode-locked fiber lasers have been receiving considerable attentions [2][3][4][5][6][7][8][9][10][11][12][13][14], because they are compact and they use commercially available optical compo-nents/devices in the cavity to produce femtosecond optical pulses with low timing jitter and high extinction ratio [2][3][4]. In recent years, optical time division multiplexing (OTDM) technology has attracted significant attention, because it can be used to eliminate the throughput bottleneck of optical communication systems/networks by optically multiplexing the modulated ultrashort optical data pulses from multiple users at the transmitting end [1], recovering the ultrashort optical clock pulses [1,6,7], and using the optical clock pulses to control the all-optical time gate(s) for demultiplexing the ultrahigh-speed OTDM data signal at the receiving end [1,5].…”

This article presented a new ladder reflector antenna on chip (AOC) which consisted of an active dipole and reflector array. The ladder structure was very easy to fabricate with the standard CMOS process. A ladder reflector antenna operating at the 24 GHz ISM band was designed with a standard 0.18 μm six metal layers CMOS process. The whole antenna had a dimension of 0.025 mm × 2.84 mm. The measurement results showed that the ladder reflector antenna got a return loss of −7.25 dB and a gain of 6.25 dBds at 24 GHz, as well as a −5 dB impedance bandwidth of 16.2–30 GHz. The measured S12 indirectly proved the simulated radiation patterns. The data taken from the experiment indicated that the ladder reflector increased the antenna gain and effectively enhanced the energy radiating to the outside of the chip. It's very useful for the wireless interconnect for inter‐chip communications. © 2008 Wiley Periodicals, Inc.
