To suppress the third-harmonic radiation, an additive-manufactured photonic bandgap material is used in the dielectric rod antenna. The antenna has been designed to operate at the frequency of 5 GHz and exhibit a bandgap at the third-harmonic frequency of 15 GHz. The design of the material is explained via the band diagram of the bandgap material and imperfections introduced due to the additive manufacturing (AM) process considered. Numerical simulations of dielectric rod antenna prototypes fed via a rectangular waveguide (RWG) with and without harmonic suppression are carried out to confirm the operational principle. The design proposed is verified experimentally. The manufactured antenna is characterized in terms of its input reflection coefficient and far-field radiation properties. The obtained experimental results agree well with predictions obtained through simulations and confirm the third-harmonic suppression capability of the antenna.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5044-5051"},"PeriodicalIF":5.8,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144781955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also explores method to enhance the conversion efficiency of THW through the utilization of Tamm state. The results show that, compared to previous analytical techniques relying on localized fields near the bandgap edge or pursuing quasi-phase matching (QPM), Tamm state demonstrates a significant 8–14 orders-of-magnitude improvement in THW. This improvement is attributed to its heightened electric field energy density and extended group delay. The transfer matrix method (TMM) is utilized to analyze the scattering effects of electromagnetic (EM) waves in the HS, effectively capturing multiple reflections and interference phenomena at the interfaces between various homogeneous media. Additionally, an auxiliary cancer cell cavity is introduced between the front and back reflection cavities. By leveraging alterations in refractive index (RI) during cell carcinogenesis, it functionally shifts the THW spectrum.

This phenomenon is due to the radiation cancellation caused by the out-of-phase currents between the parasitic element and the main radiator. This article proposes a solution by introducing another parasitic element near the initial one and enabling them to resonate in differential mode (DM), and the radiation cancellation at the efficiency dip can be significantly mitigated without attenuating bandwidth expansion. To illustrate this method, an ultrathin dual-polarized microstrip antenna is presented as an example. By designing a pair of L-shaped parasitic strips and converting the parasitic mode from common mode (CM) to DM, the in-band gain variation is reduced from 5.8 to 1.9 dB.

However, the amplitudes and phases at different harmonic frequencies are often mutually affected, which poses challenges for independent control of multiple harmonic beams. To address this issue, this article introduces a novel multibeam TMA with subarrayed time-segmented pseudorandom modulation (STPM). By dividing the ideal continuously varied modulating waveforms into multiple time segments and approximating these time-segmented waveforms with pseudorandom modulation, the proposed STPM enables subarrays to achieve accurate amplitude-phase weightings at different harmonics. Multibeam radiation in this case could be obtained by the superposition of the harmonic beams of different subarrays. Benefiting from the low-sideband property inherited from pseudorandom modulation, the proposed SPTM effectively reduces the amplitude-phase dependence among different harmonics. A multibeam pattern synthesis strategy is then developed to analytically determine the instantaneous modulation statuses of antenna elements for specified beam-scanning angles and sidelobe levels (SLLs). Compared with state-of-the-art TMAs, the presented TMA facilitates high-precision, real-time, and independent multibeam control with a significantly reduced number of modulation statuses in time modulation modules.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5559-5573"},"PeriodicalIF":5.8,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144781950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Area-efficient characteristic is obtained by the proposed power combining method compared to the conventional combiner-based or spatial power combining approach. To illustrate the working principle, the radiation efficiency of the patch antenna is analyzed and calculated based on the quality factor of the cavity model. As such, three approaches are introduced for radiation efficiency improvement of the ultralow-profile on-chip patch antenna, i.e., properly selecting the ground plane layer, enlarging the width-to-length ratio, and introducing the mirrored patches. Then, by using the characteristic mode analysis (CMA), antiphase TM20 mode and TM12 mode are introduced for impedance bandwidth enhancement. Besides, via arrays are introduced beneath the radiator to reshape the nonbroadside pattern of TM12 mode to the broadside beam. Then, a sketch is introduced to make a design guideline. Moreover, the proposed antenna is compared with three reference antennas with other bandwidth enhancement techniques to show its superiority. Finally, the proposed antenna is fabricated and measured, demonstrating advantageous performances of wide impedance bandwidth (284–322 GHz), 3-dB gain bandwidth (285–310 GHz), and high gain (5.3 dBi) without the usage of any off-chip director.","PeriodicalId":13102,"journal":{"name":"IEEE Transactions on Antennas and Propagation","volume":"73 8","pages":"5182-5197"},"PeriodicalIF":5.8,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144782082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
