The $varepsilon$ andμ of the absorbing patch can be measured and the values were assumed to vary with equal difference in the interval of 5%~30%, the measured values of $varepsilon$ and $mu$ worked as variable which were used to calculate the RCS of the almond model with the different $varepsilon$ and $mu$ of the patch. Here, two almond model RCS were obtained, one is circumferential RCS which generated by the gradient of $varepsilon$ and $mu$ of absorbing patch, and the other Radar Cross-Section (RCS) generated by the known electromagnetic parameter measurements. Comparing the two RCS mentioned above, the calculated results show that for the HH polarization, the undulation values of the almond model RCS vary within 0.4dB when the real part of $varepsilon$ and $mu$ of the absorbing patch vary within 5%-30% at 10GHz, and for the VV polarization, the undulation values changes within 2.5 dB, Moreover, the polar differences of both polarizations decrease with the increase of the real part of the $varepsilon$ and $mu$, in both polarization modes, the polar RCS is sensitive to the variation of $varepsilon$ and $mu$, and the VV polarization is much more sensitive than the HH polarization.","PeriodicalId":287986,"journal":{"name":"2021 13th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117174218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed bowtie antenna is composed of four radiated branches, and each branch consists of three hexagons, three hexagonal rings and a semi-hexagonal ring, which can generate multi-resonance and result in a wide impedance matching bandwidth. In addition, the introduction of hexagonal rings increases the current path, bringing in small antenna size (0.39AL *0.39AL *0.012AL). Two ports are utilized to feed the radiators to achieve circular polarization. To improve the circularly polarized property, two pairs of rectangles, with different dimensions in x and y direction, are added inside the four semi-hexagonal rings. Moreover, an AMC surface is designed as the ground of the bowtie antenna to achieve low-profile and high-gain performance. The presented AMC ground, made up of 12*12 units, brings the composed antenna about a low profile. The total size of the composed antenna is 84*84*8mm3(1.03AL *1.03AL *0.098AL). The simulated results show that the presented low-profile broadband bowtie antenna achieves a wide impedance bandwidth from 3.69 to 6.22 GHz (51.06%) and an axis ratio bandwidth of 55.3% (3.4GHz-6GHz). And the maximum gain can reach 8.31dBic at 4GHz.","PeriodicalId":287986,"journal":{"name":"2021 13th International Symposium on Antennas, Propagation and EM Theory (ISAPE)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123460537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, it also needs to meet the 65°±5° 3dB-width in the horizontal plane. In this paper, a bowknot-type resonator loaded dual-wideband folded dipole antenna for commercial communication base station (2-5G) applications is proposed. Compared with traditional folded dipole antenna, an additional bowknot-type resonator is introduced into folded dipole antenna. The bowknot-type resonator generates an additional new resonant mode.
