“…Recently, a novel substrate integrated suspended line (SISL) [10][11][12][13][14] has been proposed for antenna design to address most of the problems associated with patch antenna performances. In this letter, based on the SISL platform, a differential-fed antenna with a stacked patch and two symmetrical rectangular parasitic patches on the top of the main patch operating from 4.73 to 5.36 GHz is studied for the first time and applied for wireless communications.…”

A coupled differential‐fed patch antenna printed on the low‐cost FR‐4 substrate based on substrate integrated suspended line technique is proposed for wireless applications. A stacked patch is introduced on the top of the proposed antenna for bandwidth enhancement. Two symmetrical rectangular parasitic patches are placed close to the stacked patch to further enhance the bandwidth. Thus, the radiation null at the high band‐edge is generated, and 12.5% of the fractional bandwidth is obtained. The front‐to‐back ratio is greater than 18 dB at operating frequencies from 4.73 to 5.36 GHz. The measured boresight gain of the antenna is 10.8 dBi, and the radiation efficiency is 92%.

A filtering antenna consists of a reflective filtering antenna (RFA) and a bandstop filter (BSF) is presented. Due to the L‐shaped feeding structure, slots etching on the radiator and the ground plane, the RFA obtains good impendence matching, stable in‐band gain, as well as four reflective radiation nulls, and that contribute an operating band of 19% and good frequency selectivity to the proposed filtering antenna. The RFA and BSF are cascaded directly, and the compact BSF is terminated by a resistor to absorb the stopband energy of the RFA, bringing good reflectionless characteristics in a wide frequency range to the proposed filtering antenna. The proposed filtering antenna has a 2‐dB gain bandwidth of 22% (1.78–2.22 GHz), in‐band gain of about 6.81 dBi, radiation suppression levels of higher than 23.4 and 21.4 dB for the lower and upper stopbands, respectively. Within 1.0–3.0 GHz, |S11| ≤ −12 dB, implying slight effect of reflected wave on the devices connected to the proposed filtering antenna.

“…It exhibits the maximum measured bandwidth of 7% and a gain of 8.65 dB. The researchers in [9] use a driven patch, a stacked patch, and a rectangular loop to construct a multimode high gain antenna for 5G application. By adding a rectangular loop and stacked patch to the conventional patch antenna, two more additional resonance was obtained in addition to the driven patch resonance.…”

A novel compact multilayer patch antenna is designed for triple-band operation with filtering characteristics. The “U” shaped metallic loops and rectangular patch provides dual resonance of 2.45GHz and 4.15GHz respectively. While the additional middle band at 3.25GHz is attained through the employment of a slotted rectangular ring around the center patch. The bottom ground is etched with a bent horizontal slot to achieve proper positioning of the lower resonance. Besides, a coupling path is constructed from the feeding port to the radiating patches to form three radiation nulls at the lower band's edges. To position the radiation null close to the passband, the microstrip line is extended and its end is bent to avoid increasing the size. Thus a modified composite right/left-handed (CRLH) transmission line is used as the feeding structure, which is on the bottom face of the lower substrate. The via is drilled from the feedline to the top patch to realize miniaturization with better impedance matching. The designed antenna has a compact dimension of 0.21λo×0.21λo. The realized triple bands are having -10dB impedance bandwidth of 180MHz (2.31 to 2.49GHz), 400MHz (3.3 to 3.7GHz), and 1200MHz (3.5 to 4.52GHz) with a maximum gain of 5.2dB. Thus the multi-layer antenna not only has proven to be multiband but also incorporated filtering characteristics to lessen interband interferences.
