Two filtering antennas implemented on the dual-mode cavities are proposed, investigated and experimentally verified in this paper. They are developed based on the single-layer substrate integrated waveguide (SIW) technology. The rectangular SIW dual-mode cavities (using TE 102 , TE 201 and TE 301 modes) are effectively stimulated with a simple capacitive feeding near the diagonal line of the cavity. Surface current distribution is firstly analyzed for the optimal positions of slot radiators. Two rectangular slots are etched on the top surface of the SIW cavity, which are used to interfere the original current flow of one particular mode and generate radiation. These orthogonal dual-modes are used to obtain a filtering response. Their resonance frequencies are close to each other leading to field rotation and interaction with a radiation null generated outside the passband. The radiation and filtering function are achieved simultaneously by the dual-mode cavity, therefore only one cavity is required, resulting in a compact and simple antenna configuration. Good agreement has been observed between the simulation and measurement. They offer a variety of nice features, such as interesting working mechanism, lowprofile, high radiation gain and good passband selectivity, which are also suitable for high-frequency antenna application.

“…In Reference , a SIW cavity dual‐band filtering antenna with two parallel radiating slots is proposed, in which great stopband characteristics are achieved by two radiation nulls. Recently, a study has been reported in Reference , where the radiation null can be controlled from the upper stopband to lower stopband in order to effectively block interference signals. However, this design has a large size (0.72 λ 0 × 0.75 λ 0 ) and narrow bandwidth (about 6%) which limit its wide applications in mobile devices.…”

Low‐profile SIW cavity antenna with enhanced bandwidth and controllable radiation null

A low‐profile substrate‐integrated‐waveguide (SIW) cavity antenna with enhanced bandwidth and a controllable radiation null is proposed. Serving as radiating elements, two slots are etched on a square SIW cavity. Four cavity modes including a fundamental mode (FM), a half mode (HM), and two quarter modes (QMs) are excited by a capacitively coupled feeding disc. Their frequencies can be controlled by adjusting positions of the slots and disc. Three radiating modes (ie, a HM and two QMs) are utilized to realize an antenna passband with enhanced bandwidth while a nonradiating mode (ie, the FM) is utilized to achieve a radiation null resulting in the sharp upper sideband and high stopband suppression. Experimental results show that the fabricated antenna with the profile of less than 0.04λ0 obtains the bandwidth of 440 MHz, gain of 5.24 dBi, and efficiency of 84%. However, the gain sharply drops to −22.07 dBi and the efficiency achieves a very low value of 0.15% at the radiation null. Due to covering the frequency band of 3.40‐3.60 GHz, the proposed design has potential applications for fifth‐generation (5G) wireless systems.

“…The double sided SIW antenna is a 2 dielectric layered structure which irradiates the same power to opposite copper sides of antenna, so that the small cells in 5G system can be adequately covered. Recently, many SIW antennas have been proposed,4–10 but none attains the idea to increase the cell coverage in 2 directions. The main purpose of this article is to propose a 4‐by‐4 SIW slot array antenna and to demonstrate both computationally and experimentally its advantages, including compact size, broad impedance‐matching bandwidth, wide radiation pattern, small gain variation, and high radiation efficiency in both antenna sides, like an omnidirectional antenna.…”

A double‐sided substrate‐integrated waveguide (SIW) slot antenna with stripline feed, as 4‐by‐4 SIW slot array antenna, operating in millimeter‐waves bands is proposed. The whole antenna and feeding system are fabricated on a single substrate with 2 dielectric layers and 3 copper layers, which takes some advantage, such as, small size, low profile, low cost, and 2 radiation direction propagations. The design process and experimental results are presented. The prototypes can be used in dual band frequency ranges, 25 and 28 GHz, with 8 dBi gain and 63° for half power beamwidth in both sides, front and back antenna sides, and 2 GHz bandwidth. Thus, this component can be applied for 5G indoor environments.
