“…Besides, the metal ground coats the bottom of the substrate. The diameter (d) and spacing (s) of the vias can be opti-mized to maintain the conditions d/s ≥ 0 5 and d/λ 0 ≤ 0 1 (λ 0 is the free-space wavelength) to suppress the energy leakage [11].…”

In this paper, an antenna array fed in series by a novel substrate-integrated waveguide (SIW) power divider is proposed for the millimeter-wave band vital sign monitoring application. The proposed antenna is printed on a single-layer substrate, with the advantages of low profile, low cost, and ease of fabrication. By branching microstrip lines alternatively at both edges of the SIW, an in-phase power divider is first constructed. Then, by appropriately adjusting the depth of microstrip branches into the SIW, the amplitude of the output power can be tuned to obtain the desired amplitude distribution. Patches are connected to the microstrip branches, respectively, and thus, a radiation pattern with a low sidelobe level is realized. More importantly, series patches can be cascaded to enhance the array gain without the additional feeding network. This leads to a compact configuration. Based on the proposed idea, a prototype is designed, implemented, and tested. The results indicate that the proposed array achieves a maximum gain of 17.8 dBi with a low sidelobe level of -25.5 dB. The attractive performance shows that the array is suitable for the millimeter-wave vital sign monitoring application.

A broadband circular arc-shaped slot antenna is proposed in this paper which operates from 25.1 GHz to 31.5 GHz. The antenna is based on a substrate-integrated waveguide (SIW) and fed through a grounded coplanar waveguide (GCPW). A circular arcshaped slot is presented instead of a conventional narrow rectangular slot to extend bandwidth performance. The slot antenna generates six closely resonant frequencies by exciting high-order modes, which help get a broadband response. Antenna's prototype is fabricated using the standard Printed Circuit Board (PCB) process. The results of its measurement show that the antenna achieves an impedance bandwidth of 22.6% at 28 GHz and a peak gain of 11.5 dBi. The efficiency in the operating bandwidth is more than 85%. The antenna shows the merits of low-profile, high-gain, and broadband characteristics, which are very suitable for mm-wave wireless communication systems.

“…Generally, waveguide slot antenna (WSA) with back cavity can overcome this problem, 4 but it has a large volume. Substrate integrated waveguide (SIW) 5 which has the planar structure and the characteristics of rectangular waveguides has attracted much attention since it was proposed. Thereupon, a PSA backed by SIW cavity, which integrates a back cavity, a feeding and a radiating unit on a single substrate, has been proposed 6 .…”

In this paper, a directivity‐enhanced planar slot antenna (PSA) backed by substrate integrated waveguide (SIW) cavity is proposed to solve the problem of maximum gain direction bias. According to the radiation principle of slot antenna, the reason for maximum gain direction bias is explained and the solution has been given. Ulteriorly, the problem of frequency bias caused by changing the directivity is also explained by resonance modes and solved by introducing the metal via. An example with 5.8 GHz which has the maximum gain of 5.28 dBi and the total thickness less than λ/4 is given. After structural optimization and measurement, the maximum radiation direction of improved antenna is 0° from the normal direction of antenna surface, and it maintains the good radiation performance and small size of the traditional PSA backed by SIW cavity.
