This paper demonstrates a novel kind of cavity-backed self-quadplexing slot antenna for the S and C-band applications. The proposed antenna consists of 4 distinct “U”-shaped slots of different lengths and produces the quad frequency band for wireless communication systems. These slots are excited through the separate and orthogonal placed microstrip feed lines of 50 Ω; generates four distinct operating bands at 3.2 GHz, 4.1 GHz, 5.8 GHz, and 7.2 GHz. Due to the perturbation of different U-shaped slots over the substrate integrated waveguide (SIW) cavity with defined positions, the high intrinsic port isolation value is better than 30.5 dB. Thus, the proposed unique antenna structure combines the four independent operating bands with minimum mutual coupling and negligible interference among input ports, which shows the self-quadplexing feature of the antenna. The proposed antenna also has the property of frequency tunability with uni-directional radiation pattern and gain of 5.8 dBi, 5.4 dBi, 4.01 dBi, and 3.47 dBi at corresponding operated frequency. The cross-polarization is 17.3 dB and the front-to-back ratio higher than 21.5 dB at all operating quad bands. There is a good agreement between simulated |S|-parameters results and equivalent circuit model results.

“…Over the last few years, substrate-integrated waveguide (SIW)-based antennas have received a lot of attention due to their small size, multi-band operation, superior isolation, and enhanced radiation properties [8][9]. Recently, many self-diplexing antennas [10][11][12][13][14], self-triplexing antennas [15][16][17][18], self-quadruplexing antennas [19][20][21][22][23][24], and selfmultiplexing antennas for hexaband applications [25][26] have been reported. Generally, two, three, four, and six feeding ports are applied to develop self-diplexing, selftriplexing, self-quadruplexing, and self-multiplexing antennas that radiate at dual, triple, quad, and hexa operating bands, respectively.…”

This article presents a novel compact self-quintuplexing antenna architecture based on a substrateintegrated rectangular cavity (SIRC) for pentaband applications. The proposed self-quintuplexing antenna is constructed by employing an SIRC, one Pi-shaped slot (PSS), one T-shaped slot (TSS), and five 50Ω microstrip feedlines. The PSS and TSS are engraved on the top of the SIRC to create five radiating patches, which are excited by five 50Ω feedlines to achieve pentaband operation with self-quintuplexing characteristics. The resonating frequencies can be tuned independently based on the dimension of the radiator without disturbing other bands. A detailed parametric analysis is carried out to provide a suitable frequency tunable range and high isolation. In addition, an equivalent lumped circuit is developed to analyze the proposed self-quintuplexing antenna. To validate the proposed antenna architecture, an SIRC-based self-quintuplexing antenna operating at 2. 29, 2.98, 3.65, 4.37, and 5.08 GHz is fabricated and demonstrated. The fabricated antenna offers competitive performance with a compact size of 0.173λ 2 , pentaband operation, high isolation of 29.31 dB, and a wide frequency tunability range from 2.29 GHz to 6.03 GHz. Furthermore, the fabricated self-quintuplexing antenna exhibits the measured realized gain of 3.

SummaryIn this paper, a high gain self‐triplexing antenna based on the substrate integrated waveguide (SIW) leaky wave technology is presented for tri‐frequency operation. Three identical T‐shaped slots are embedded on the upper layer of the proposed SIW antenna, which are energized by two tapered microstrip lines and a simple microstrip line; and the antenna resonates at three different frequencies (7.75 GHz, 9.1 GHz, and 10.15 GHz). The transverse part of the T‐slot achieves the first band (8.8 to 9.3 GHz), while the longitudinal part of the T‐slot achieves the second band (9.6 to 10.9 GHz), and when excited transversely, the T‐slot achieves the third band (7.5 to 8.2 GHz). The isolation level between the ports is more than 25 dB, which contributes to the phenomenon of self‐triplexing. The gain of the presented antenna is high when compared with other self‐triplexing antennas.
