This communication presents a novel concept of microfluidically frequency-reconfigurable self-quadruplexing tunable antenna for quad-band applications. At the initial design stage, a substrate-integrated square cavity is divided into four unequal quarter-mode cavity resonators by inserting an X-shaped slot on the top surface of the cavity. Applying four 50-Ω microstrip feed-lines to these four quarter-mode cavity resonators enables quad-band operation with self-quadruplexing capabilities. The feed lines are organized orthogonally and off-center, which leads to port isolation greater than 32.3 dB. An equivalent network model is developed to validate the proposed antenna. To realize frequency reconfigurability, two microfluidic channels corresponding to each port are created by engraving the bottom surface of the cavity. To create a reconfigurable self-quadruplexing antenna, the channels are either filled with air or dielectric liquids of higher permittivity, so that the design offers independent tunability of the operating frequencies. As a proof of concept, the prototype of a self-quadruplexing tunable antenna is fabricated and validated through measurements. The antenna prototype occupies a footprint area of 0.37λg2. The design exhibits frequency tuning ranges of 350 MHz (8.3%), 500 MHz (10.3%), 610 MHz (11.2%), and 845 MHz (14.1%) for the first, second, third, and fourth operating bands, respectively. In all bands and across the entire tuning range, the realized gains of the designed antenna exceed 4.05 dBi. The electromagnetic modeling responses agree extremely well with the measured characteristics.

“…To get one or more than one band, dual-feed/dualpolarization, di/tri/quad-flexing, and slot/stub techniques are used to minimize the antenna footprint. In this way, the dual-feed/polarization can be an excellent alternative to conventional miniaturized single-band operation [3,4]. Moreover, the antenna footprint with sustained port isolation explores new ideas based on SIW self-multiplexing antenna [5][6][7].…”

A compact dual-feed multiple-input multiple-output (MIMO) antenna is designed for sub-6 GHz 5G applications with isolation enhancement. The proposed dual-polarized MIMO antenna formed by each patch uses two inset-feed lines placed orthogonal to each other with symmetric conditions, which excite each port to resonate at the same frequency (3.65 GHz). The stub is identified diagonally based on plated through-hole technology between orthogonal ports. The structure employs a half mode and maintains minimum interport isolation (≤ −12 dB) of each patch, followed by another patch to form an 8-element miniaturized MIMO antenna. High isolation (≤ −15 dB) is achieved with the help of a decoupling structure placed between the antennas in the ground plane. Measurements of a fabricated prototype validate the simulation results. The diversity performances of MIMO antenna parameters like envelope correlation coefficient (ECC), diversity gain (DG), and Mean Effective Gain (MEG) are also found within acceptable ranges.

“…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.…”

A cavity-backed bowtie-ring slot [10], a U-shaped slot [11], a shielded SIW cavitybacked Y-shaped slot [12] and two U-shaped slots [13], and two coaxial feed-modified half-mode SIW (HMSIW) cavity [14] have been demonstrated for the self-diplexing antennas (SDAs).

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.
