“…The SIW feeding network in this work is a little similar with that in Ref. , which included a 180° phase shifter and power divider. The four sub‐arrays and the SIW feeding network, including a 90° 3‐dB coupler, power dividers and three 90° phase shifters that are realized by tuning the width of SIW, are integrated on a single‐layer substrate.…”

This article presents the design and implementation of a single-layer wideband millimeter-wave circularly polarized (CP) monopulse cavity-backed antenna based on substrate integrated waveguide (SIW) technology. The antenna consists of a 2×8 array of CP cavity-backed antenna elements, a 90 3-dB coupler, power dividers, and phase shifters. In order to enhance the operating bandwidths, the sequential rotation feeding technology is adopted in the design of the monopulse antenna. To validate the proposed concept, a prototype operating at 42 GHz was fabricated and measured. The measured 3-dB axial ratio (AR) bandwidth for the sum beam can cover a frequency range from 37 to 46 GHz. The measured gain for the sum beam at the center frequency of 42 GHz is 17.5 dBiC, while the null-depth of the difference beam is measured to be −36.8 dB. The proposed monopulse antenna has advantages of low-cost, easy-fabrication, and easy integration with planar circuits.

“…However, the narrow bandwidth greatly limits its imaging resolution. According to current research, reducing the quality factor [1,2], installing stacked parasitic patches [3,4], and compensating capacitors [5] have become mainstream broadband techniques. By synthesising the stacked patch and slot coupling technology, the dual-polarised antenna in [6] achieved 26.37 and 27.77% impedance matching bandwidth in the horizontal and vertical polarisation directions, respectively, however, its profile was as high as 0.21λ 0 .…”

“…This miniaturised antenna of only 0.42 × 0.42 × 0.069λ 0 achieved an impedance matching bandwidth of 22.3% and an average gain of 7.15 dBi. Its equation (2) shows that as the step-shaped metasurface becomes thicker, the unit cell bandwidth and operation bandwidth will also be optimised due to the increase of the parallel inductance L d .…”

In this paper, a novel technology based on double‐layer metasurfaces is proposed in order to broaden the bandwidth of microstrip antennas, which has been verified in X‐band linearly polarised and circularly polarised antennas. Referring to the conventional metasurface antenna that employs slot‐coupled feeding, these designs add an extra metasurface between the radiation patch and the ground plane so as to establish dual resonance modes, TM10 and TM20. Following the adoption of the composite right/left‐handed transmission lines principle, this technique aims to adjust the propagation constant in the right‐hand region by introducing parallel inductors and capacitors to widen the dual resonant frequencies' interval, thereby realising a broadband antenna. In addition, the interlayer metasurface may also be utilised as a director to balance the E‐field of the radiation patch. A linearly polarised double‐layer metasurface antenna with a size of 0.8×0.8×0.058λ0 (wavelength in free space at the centre frequency) is filled with F4B substrate with a dielectric constant of 2.2. It finally realises an impedance matching bandwidth (VSWR≤2) from 8.41 to 11.67 GHz, occupying about 32.47normal% of the centre frequency. This circularly polarised antenna attains both an impedance matching bandwidth of 32.44normal% (i.e. 8.29–11.5 GHz) and an axial‐ratio bandwidth of 19.72normal% (i.e. 9.6–11.7 GHz).

“…Antennas have been widely used in many communication applications, such as radar and wireless communication systems [1]. Recently, intra/inter-chip wireless communication has drawn great attention in the areas of computer system design and trace wiring topologies [2,3], which is primarily due to the signal integrity issues of crosstalk, signal distortion, and trace loss of the traditional metal wiring interconnection.…”

Here, a silicon‐substrate‐based four element antenna system is investigated by using a coplanar frequency selective surface (FSS) as a novel parallel reflector to improve radiation and transmission characteristics of the antennas. The four antennas are arranged around the square FSS, and one of the antennas is used as the transmitting element, while the other three as the receiving ones. It is found that, owing to the stopband filtering and the linearly changing reflection phase of the designed coplanar FSS, the gain and directivity of the transmitting antenna have been greatly improved, and that the antenna system transmission coefficients, including S21, S31 and S41, have been significantly increased. Two types of the antenna systems have been designed and fabricated on a P‐type silicon wafer substrate for the cases with and without a coplanar FSS reflector. The measured S‐parameters are essentially consistent with those simulated. In comparison with the case without the FSS, the transmission coefficients of S21, S31 and S41 for the system with the FSS have been increased about 6.42, 5.97 and 5.89 dB at the center frequency of 5.42 GHz, respectively. Furthermore, the proposed coplanar FSS exhibits distinct advantage of low‐profile compared to the conventional vertical FSS reflector.
