“…The proposed four‐port self‐quadruplexing antenna is compared with some published single port multiband/quad‐band 1‐3 and some self‐multiplexing 11‐13 and 14‐18 antennas in Table 2. Unlike other antennas, 1‐3 the self‐multiplexing antennas do not require external multiplexing circuit and allows independent frequency tuning.…”

“…Compared to other self‐di/triplexing antennas, 11‐16,20 the proposed self‐quadruplexing antenna seems improved in terms of size and antenna type. However, its size, isolation, and front‐to‐back ratio (FTBR) levels are improved than other self‐quadruplexing antennas 17,18 …”

“…However, to meet the future communication demand there is absolute need of a self‐multiplexing antenna. In this prospect, recently one self‐quadruplexing antenna 17,18 is reported in the literature, which can operate at four different frequencies simultaneously. However, design method for an all‐planar fed self‐quadruplexing antenna with improved port isolations and compact size is highly desirable.…”

This article presents a simple, compact, and lightweight substrate integrated waveguide (SIW) backed self‐quadruplexing antenna for quad‐band applications. The design procedure is straightforward. Topside of the SIW cavity is modified to form four patches of different lengths which are fed separately by four 50‐Ω microstrip feed lines and operate at 5.14, 5.78, 6.74, and 7.74. It attains 4.1, 4.96, 6.2, and 6.1 peak gain at the above frequencies, respectively. The observed front‐to‐back‐ratio is more than 17.5 dB and the isolation level is above 28 dB. This antenna topology allows to redesign each resonant frequencies as per application requirement using a single parameter and without disturbing other performances. Design guidelines for developing the proposed antenna are provided. A prototype antenna is fabricated using RT‐Duroid (5870) substrate and characterized for validation. The proposed antenna is suitable for handheld microwave devices for C‐band communication.

In this paper, a miniaturized quarter-mode substrate integrated waveguide (QMSIW)-based self-multiplexing antenna is designed to achieve high isolation in terms of small-frequency ratios. First, the cross-shaped slot is introduced to split the antenna into four parts with different dimensions, equivalent to four QMSIWs with different frequencies. By adjusting the slot position parameters, the QMSIW can be adjusted independently. Second, the antenna placement is optimized by adjusting the position of the slot and applying the frequency spacing technique. The designed antenna operates in four similar frequency bands (4.8, 5.15, 5.5, and 5.8 GHz). The isolation of adjacent units is more remarkable than 35.1 dB, while the isolation of relative units is more excellent than 22.7 dB. The structure of the proposed planar antenna is simple and suitable for handheld microwave devices.
