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 ...

“…It is evident that the rectangular-patches participate towards a y-axis polarized radiation, and the circular patches participate towards both x-and y-axis polarizations, to yield left-handed circularly polarized radiation. The antenna's radiation specifications were tested applying a compact antenna test range as illustrated in [16]. The antenna measurement setup with the attached horn antenna on the transmitter is shown in Fig.…”

This article investigates the feasibility of designing a wideband high-gain on-chip antenna on silicon technology for sub-terahertz applications. High-gain is achieved by exciting the antenna using an aperture fed mechanism to couple electromagnetics energy from a metal slot-line, which is sandwiched between the silicon and polycarbonate substrates, to a 15-element array comprising circular and rectangular radiation patches fabricated on the top surface of the polycarbonate layer. An open ended microstrip line, which is orthogonal to the metal slot-line, is implemented on the underside of the silicon substrate. When the open ended microstrip line is excited it couples the signal to the metal slot-line which is subsequently coupled and radiated by the patch array. Measured results show the proposed on-chip antenna exhibits a reflection coefficient of less than-10 dB across 0.290 THz to 0.316 THz with a highest gain and radiation efficiency of 11.71 dBi and 70.8%, respectively. The antenna has a very narrow stopband between 0.292 THz to 0.294 THz. The physical size of the presented subterahertz on-chip antenna is 20×3.5×0.126 mm 3. Index Terms-Terahertz (THz) On-chip antenna, coupling feeding mechanism, integrated circuit, high gain, silicon technology, broad bandwidth.

Phaseless Characterization of Compact Antenna Test Range via Improved Alternating Projection Algorithm

A practical compact antenna test range (CATR) requires good quiet zone quality for antenna characterization. This paper addresses the phase profile of the CATR quiet zone from the known intensity pattern of spatial domain and Fourier domain based on a combined alternating projection algorithm. The proposed algorithm is composed of Gerchberg–Saxton (GS) and Hybrid Input–Output (HIO) algorithms and the two algorithms with spatial phase perturbation (SPP) work collaboratively or independently under predesigned conditions. It is observed that the algorithm with random initial phase guess can always converge to an optimal solution by performing a series of hierarchical optimizations of the problem. The numerical results are in good agreement with simulated results in different frequency bands, overcoming the phase retrieval limitation of local convergence in the iterative process. Furthermore, to validate the effectiveness and robustness of the proposed procedure, the related discussions corresponding to different sampling areas in Fourier domain and different signal to noise ratios (SNRs) are given.
