“…Using fullwave electromagnetic simulation software to simulate the dual polarization antenna design and optimization with the bandwidth between 4.9 GHz and 5.1 GHz, the antenna port International Journal of Antennas and Propagation isolation, cross-polarization level, beam width, and other technical indicators meet the requirements of dual polarization antenna; especially, the dual polarization antenna has a very wide polarization pattern; namely, in the wide range of space angle, the two polarization channel has good orthogonality, which can be used in dual polarization radar and communication systems. The polarization pattern of this antenna is wider than the compact dual polarized slot antenna with an enhanced gain in the literature [1][2][3][4][5]. The designed dual polarization cascade printing antenna is processed and tested, and the experimental results verify the effectiveness of the proposed dual polarization antenna.…”

“…The design and implementation of dual polarized antenna have become a hotspot in the field of antenna technology [1][2][3]. In terms of structure, dual polarized antennas include dual polarized dipole antennas, dual polarized microstrip antennas, and dual polarized mouth antennas [4][5][6]. From the radiation mechanism, the dual polarization antenna can be divided into the electric current source and magnetic current source with orthogonal placement.…”

This paper presents a dual polarized antenna with high isolation for a wide-angle scanning phased array radar. For the proposed antenna, the electronic and magnetic resources are realized through a printed monopole antenna and a slot ring antenna, respectively. A metal reflector ground was introduced to achieve the unidirectional pattern, and the ratio of front to back of the pattern was improved. The printed monopole and slot ring antenna are fed by the coaxial and electromagnetic couplings, respectively. The radiation fields emitted by the electronic current resource and magnetic current resource are approximately orthogonal to each other among large space ranges. The measured port isolation of the designed antenna is above 20 dB, and the wide beam performance can be observed. The feasibility of the proposed antenna scheme is verified.

“…Interlayer transmission is achieved by etching a cross slot on the copper layer between the two laminates. The orthomode transducer can be considered as a six-port differential network or a polarization duplexer [27], [35], [36]. It is often used to combine or to separate two orthogonally polarized waves received by or transmitted from a differentially-fed dualpolarized antenna.…”

This paper presents a new design of a differentiallyfed substrate integrated planar antenna array with dualpolarization. Compared with the traditional dual-polarized antenna arrays, the proposed array antenna has the advantages of simple configuration, high cross-polarization discrimination (XPD) and high gain. 2 × 2-element subarray design with a vialoaded crossover structure is used, which reduces the complexity of the array antenna. The operation bandwidth is improved by generating three resonances in the subarray. An 8 × 8 antenna array is designed, prototyped and tested to exemplify its potential applications in large dual-polarized antenna arrays. A planar orthomode transducer is used to achieve differential excitation for the antenna array. The measured results show that the proposed antenna array has an impedance bandwidth of 19.2-20.7 GHz for |S 11 | < −10 dB and port isolation higher than 20 dB. The array antenna exhibits a high XPD of 43 dB and a flat gain about 22.2 dBi within the bandwidth.

This paper introduces a planar orthomode transducer (OMT) using substrate integrated waveguides (SIWs) and substrate integrated coaxial lines (SICLs) that is entirely contained within two substrate layers. SICLs form a quadruplet of probes inside the metal waveguide with fully symmetrical geometry. Such a structure is smaller and lighter than a waveguide OMT, its construction is simpler than of a coaxial OMT, however, isolation and loss properties are less degraded compared to the use of planar unshielded technologies such as microstrip. A new wideband inline SICL to SIW transition has been developed to allow grade separation of SIWs belonging to opposite polarizations through different substrate layers. The designed substrate integrated probe-based OMT on RO4003C TM substrate covers the frequency band from 8.1 to 12.5 GHz with return loss higher than 19 dB, insertion loss less than 1.2 dB, inter-port isolation higher than 62 dB and cross-polarization discrimination higher than 65 dB.
