“…When compared to the most compact SMA of [21], the proposed SQA has a 24.8-percent smaller footprint. It also exhibits the highest isolation of 29.3 dB as compared to the reported self-multiplexing antennas [18][19][20][21][22][23]26], except [21].…”

“…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.…”

“…In [24], two U-shaped slots have been loaded on the cavity to realize a self-quadruplexing antenna. In [25][26], selfmultiplexing antennas (SMA) have been constructed by producing rectangular patches on top of a SIW cavity for hexa-band applications. Although the aforementioned selfmultiplexing antenna structures have competitive performance, it is still challenging to construct a selfquintuplexing antenna that is compact yet exhibits high isolation and pentaband operation.…”

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.

“…A SIW also offers miniaturization by dividing a single cavity into sub-cavities, such as the HMSIW, QMSIW, and eighth-mode SIW (EMSIW), because the dominant mode field distributions of these cavities are similar. This can be implemented using multiplexed antennas [15], [16], [17], [18]. However, multiplexing antennas [15], [16], [17], [18] and HMSIW CBS antennas with single resonant frequencies [19], [20] have narrow impedance bandwidths.…”

A substrate-integrated waveguide (SIW) antenna is an implementation of a waveguide antenna in a microstrip antenna. The microstrip antenna, as a low-profile antenna, suffers from narrow impedance bandwidth. This paper proposes a novel bandwidth enhancement method for solving a narrow impedance bandwidth. Bandwidth enhancement was achieved by using quad-resonant frequencies. The quad-resonant frequencies are resulted from the hybrid half-mode substrate-integrated waveguide (HMSIW) cavities between the inner and outer cavities. The inner HMSIW cavity has a half-pentagon ring slot that disturbs the TE 101−inner , TE 102−inner , TE 202−inner , and TE 103−inner modes, whereas the outer HMSIW cavity consists of two outer quarter-mode substrate-integrated waveguide (QMSIW) cavities. The outer HMSIW cavity generated the TE 102−outer and TE 202−outer modes. The hybrid cavities were fed simultaneously using a port with a quarter-wavelength feed transmission line. The hybrid HMSIW cavities generated resonant frequencies that were close to each other. Additionally, this method was applied to the X-band frequency with a low-profile substrate. The simulated impedance bandwidth and peak realized gain was 33.86% (8.98 − 12.64 GHz) and 7.97 dBi, while the measured impedance bandwidth and peak gain were 31.83% (9.14 -12.6 GHz) and 7.62 dBi, respectively. Strong agreement was observed between the measurement and simulation results.INDEX TERMS Bandwidth enhancement, hybrid cavities, quad-resonant, a half-pentagon ring slot, halfmode substrate-integrated waveguide antenna.
