To implement a self-diplexing operation, the half-mode substrate-integrated waveguide (SIW) cavity is loaded with a rectangular slot carved on the top metal cladding. This causes the cavity to be divided into two unequal apertures, resulting in the development of a quarter-mode SIW. The patch has orthogonally positioned feed lines that provide two distinct resonant frequencies, 5.18 GHz and 5.8 GHz, with respect to the fundamental mode <inline-formula><tex-math>$text{TE}_{110}$</tex-math></inline-formula>. Employing metallic vias on the cavity improves the self-isolation between the orthogonal ports. Furthermore, a square aperture between orthogonal patches can achieve maximum isolation without additional units. The proposed compact MIMO antenna with a self-diplexing feature using an aperture slot achieves maximum isolation of 46.84 dB at 5.17 GHz and 42.76 dB at 5.8 GHz between patches, interport isolation of 28.6 dB at <inline-formula><tex-math>$f_{L}$</tex-math></inline-formula> and 27.6 dB at <inline-formula><tex-math>$f_{H}$</tex-math></inline-formula> among ports, an impedance bandwidth of 130 MHz (5.236 GHz to 5.106 GHz) and 174 MHz (5.88 GHz to 5.72 GHz), and high gain of 4.5 dBi, and 5.46 dBi was achieved at 5.17 GHz and 5.8 GHz, respectively.

In this scheme, a ground plane and a three-sector M-shaped sheet with a top-loaded patch are excited by a 50 Ω coaxial cable, aiming to achieve excellent impedance and vertical-polarized omnidirectional radiation performance within a broad bandwidth. Subsequently, a three-sector fan-shaped patch with three metal holes, three I-shaped slots and three 1.0λ resonant rings are successively introduced to create two stopbands at 2.75 GHz to 3.25 GHz and 4.25 GHz to 4.37 GHz, thereby dividing the ultra-broad band into three desired bands. In our design, the notched bands can be controlled by altering the sizes of the fan-shaped patch, metal hole, I-shaped slot, and resonant ring. The test results indicate that the proposed antenna has three operating bands at 1.44 GHz to 2.76 GHz, 3.19 GHz to 4.36 GHz, and 4.50 GHz to 4.70 GHz.

The symmetric tapered slots are etched for CP condition. The periodic ridge structures are introduced between the transition ridge and periodic pins to increase the current path. By this means, the appropriate phase differences of orthogonal electric fields are achieved within a compact radiation aperture. The bent dipoles are added at the end of the tapered slot to improve the amplitude and phase condition at lower frequency. Additionally, the gradient transitions from the ridge to the radiation aperture are adjusted for wide impedance matching performance. To validate the proposed antenna, a 1 × 4 CP array fed from the double ridge GWG power divider was fabricated and measured. A measured bandwidth of 32.6% [(28.2 to 39.2) GHz] for both <italic>S</i><sub>11</sub><−10 dB and AR < 3 dB is achieved. Taking advantage of the double ridge GWG, the radiation performances of this antenna are measured with symmetric patterns and a peak gain of 15 dBi. Besides, the efficiency of this antenna is more than 74.5% over the frequency band.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 6","pages":"1452-1456"},"PeriodicalIF":3.7,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MB 1, MP, and MB 2 are sequentially incorporated at the center of the patch. As the current flows from the microstrip line to the patch, a portion of the current simultaneously enters MB 1, MP, and MB 2, resulting in a distribution of current on their surfaces. Due to the out-of-phase current distribution between the radiators, the radiation fields among the radiators cancel each other, and the radiation fields both at the E- and H-plane counteract each other, creating radiation nulls at these planes while redistributing part of the energy toward the main lobe, thereby enhancing the gain. Concurrently, the radiators with in-phase current distribution concentrate radiation energy in the direction of the main lobe, strengthening the intensity of the radiation field in the main lobe and further optimizing the gain performance of the antenna. Moreover, an additional resonant point is introduced, which increases the impedance bandwidth of the antenna according to the principle of band superposition. Both simulation and measurement results confirm the operational mechanism of this design, demonstrating an increase in gain by nearly 7.5 dBi and an increase in bandwidth by 13.8% compared to conventional differential-fed patch antenna.","PeriodicalId":51059,"journal":{"name":"IEEE Antennas and Wireless Propagation Letters","volume":"24 6","pages":"1462-1466"},"PeriodicalIF":3.7,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
