“…The antenna arrays in Refs. [10] and [12] shows comparable bandwidths with the proposed one, but the antenna elements are fed by CPW that may result in low radiation efficiency and large back-lobe radiation. Besides, the radiation patterns of the antenna array in Ref.…”

“…Nevertheless, the bandwidth of conventional SIW slot arrays can hardly be further enhanced due to the inherent narrow bandwidth of the slot radiator. Other types of SIW antenna arrays have also been proposed for mmW applications, including patch [9], [10] cavity [11], magnetic-electric (ME) dipole [12], and planar aperture [13] antenna arrays. Although some of these designs [10], [12] achieved wide bandwidths (29%-35%), they suffer from complex feeding structures or unstable gains.…”

This work investigates the use of substrate integrated waveguide fed open slot antenna (WOSA) in an array for the first time to provide a new SIW slot antenna array with wide bandwidth and single-layer structure. The antenna array consists of 4×2 substrate integrated WOSA elements as a radiating part and two 1-to-4 SIW power dividers as the feeding network. The whole array is differentially fed and built on a singlelayered laminate. To demonstrate the wideband performance of the substrate integrated WOSA elements, two sets of feeding networks designed at different frequencies are used to feed the same radiating part. In this way, a V-band and a W-band array were built. Both the antenna arrays were fabricated and measured. Benefiting from the excellent performance of the substrate integrated WOSA elements, the antenna array achieves a wide bandwidth of 32.3% (54.0 to 74.8 GHz) with a peak gain varies from 11.3 to 15.6 dBi. It has been demonstrated that the substrate integrated WOSA array can achieve a wide bandwidth with a single-layer structure, which is attractive for millimeter-wave applications.

“…Although the antenna in [15] utilizes the higher-order resonant modes (TE 130 , TE 310 , TE 330 ) which yields the wide fractional bandwidth (>26%), it occupies a much larger SIW cavity size. The third type is to load a patch onto the cavity through a slot, combining the cavity mode with additional resonant patch mode [18], [19]. In [18], a cavity mode TE 210 and an additional patch mode are excited to achieve a bandwidth of 15%, which, in fact, is still narrow.…”

“…In [18], a cavity mode TE 210 and an additional patch mode are excited to achieve a bandwidth of 15%, which, in fact, is still narrow. Moreover, the published SIW CBSAs are mainly implemented with the ordinary rectangular cavities [4]- [19], circular cavities [20][21][22][23][24][25], triangle cavity [26], and hexagonal cavity [27]. To this end, novel broadband antenna topologies need to be further explored to utilize more cavity modes, aiming to exhibit a wider bandwidth to satisfy the increasing requirement from the modern communication system.…”

Substrate integrated waveguide (SIW) elliptical cavity-backed slot antennas (CBSAs) with either penta-or hepta-resonance are characterized and designed for wideband performance in this paper. First, the resonant behavior of the elliptical cavity is explored. Then the SIW CBSA with penta-resonance is designed by introducing a cross-shaped slot and a pair of unbalanced shorting vias into the cavity to excite two additional odd-and even-half degenerate quasi-TM 110 modes, besides other three modes of half quasi-TM 010 , and odd-and even-quasi-TM 110. Further, by adding another pair of unbalanced shorting vias, two extra higher-order modes, i.e., odd-and even-quasi-TM 210 modes are successfully introduced to design a hepta-resonance antenna. The corresponding mode analysis and design guidelines are discussed in detail. Two prototypes are fabricated and measured at X-band, exhibiting the measured bandwidths of 21.8% and 22.7%, respectively. Measured results agree well with simulations, thus validating the design concept.

“…During the past years, numerous methods have been proposed to enhance the bandwidth of MPAs, such as increasing the thickness of the substrate [8,9], decreasing the substrate dielectric constant [10,11], loading chip resistor [12], using parasitic patches in single layer and multilayers configuration [13][14][15], employing electromagnetic band gap structures [16][17][18][19], and using backed edge-fed cavity [20,21]. However, most of these MPAs are made by adding additional structure so that their structures become more complex.…”

By using complementary rhombus resonator (CRR), a small-size and low-profile microstrip patch antenna (MPA) with broad bandwidth has been proposed. Parametric studies were conducted to illustrate the working principle of the proposed antenna. An additional resonance is introduced by the CRR to broaden the bandwidth. Compared with the MPA without the CRR, the bandwidth of the proposed antenna is increased by 200%. The measured results are in good agreements with the simulated ones, which demonstrate that this design provides a way to obtain the broadband antenna.
