“…The proposed STA achieves an ultracompact size, high isolation, and excellent realized gain, according to the table. The proposed STA has a smaller footprint area than those in [2,5,7,10,11,[25][26][27]. Furthermore, the suggested STA is 50% smaller than the most compact STA reported in [27], and there is no significant difference in the realized gains.…”

“…Furthermore, the suggested STA is 50% smaller than the most compact STA reported in [27], and there is no significant difference in the realized gains. The proposed STA has a minimum port isolation of 32.4 dB across all bands, which is greater than the isolation level obtained in previously documented antennas [2,5,7,10,11,[25][26][27]. It should be mentioned that the proposed STA includes a lumped-circuit model to analyze the antenna's working principle, whereas, with the exception of [26], no lumped-circuit model was provided for antenna analysis in [2,5,7,10,11,25,27].…”

“…Therefore, current research has focused on creating multiband antennas, with monopole-, slot-, and SIW-based structures being the most prevalent architectures [2][3][4][5][6][7][8][9][10][11]. A rectangular monopole truncated patch loaded with a U-shaped slot was employed for the design of a tri-band millimeter-wave antenna in [2].…”

“…A triband dualpolarized antenna was constructed by using cross-shaped slots and L-shaped slots in [5]. A triband antenna was developed based on a substrate-integrated waveguide (SIW) loaded with a pair of open-loop slots in [7]. In [8], a triband antenna was realized on a half-mode SIW loaded with multiple slots.…”

An ultracompact self-triplexing antenna realized on a substrate-integrated rectangular cavity (SIRC) is discussed in this study. The proposed structure employs two L-shaped slots and an inverted U-shaped slot to radiate at three independent operating frequency bands. Three 50-ohm microstrip feed lines were used to excite the radiation in these slots. The operating frequency was individually tuned using the slot size. The slot placement and size were designed having in mind considering obtaining one or more frequency bands below the SIRC cutoff frequency, which had the advantage of enabling an ultracompact size. High port isolation was achieved by applying one of the ports orthogonally to the two remaining ones, which created a weak cross-coupling channel. A lumped-circuit model was created to examine the antenna operation. The presented design has been prototyped and experimentally validated with the measured operating frequencies of 1.92 GHz, 4.43 GHz, and 5.25 GHz for GSM, 5G, and WLAN applications, respectively. The port isolations are better than 32.4 dB according to both EM simulations and measurements. Meanwhile, the measured realized gain of the antenna is better than 4.3 dBi at all bands.
