“…In addition to this, many electromagnetic dipole antennas have essential wide beamwidth radiation patterns. [10][11][12][13] The three dimensional printing technology has been significant focused due to flexibility in the choice of materials, capability to fabricate complex structures, and including time saving. 14 In the microwave region, there are many reports of antenna designs with three-dimensional printing technology.…”

In this article, a novel lens antenna with wide beamwidth using three-dimensional printing is proposed. The proposed antenna is comprised of a concave lens by using three-dimensional printing, a lantern shaped patch with a parasitic ring, and eight loaded monopoles around the center. The antenna operating frequency is 5.8 GHz, and the prototype is implemented. The measured half power beamwidth are 142 and 130 at the xoz and the yoz planes, respectively. Besides, the antenna is low cost, easy to fabricated, and very low cross polarization. Measured results agree well with the simulation results.

“…On the other hand, high isolation in a compact size is always a challenging research topic for dual-polarized antennas. So far, many studies with great efforts have been made in this aspect [17], [18]. In [17], by placing four Vshaped patches around the radiating patches and introducing orthogonal feeding scheme, high isolation of better than 25 dB with a compact size of 40×40×1.524 mm 3 can be achieved in the bandwidth of 3.0-4.1 GHz.…”

A dualband dual-polarized antenna element with dual wide beamwidths for 5G microcell applications is initially proposed and investigated in this paper. To achieve very low manufacturing cost, an unprecedented method is applied to the antenna element, in which the antenna components are printed separately on F-4B substrates, follow by assembling them to form the antenna element (similar to building block assembly). To further achieve high gain, an 1×4 antenna array is also designed. Measured results show that the half power beamwidths (HPBWs) in Hand E-planes are 112±1 • and 105±3 • in the lower frequency band of 3.22-3.88 GHz, respectively, and 99±3 • and 106±4 • in the upper frequency band of 4.52-5.02 GHz, respectively. In addition, high front-to-back ratio (FBR) of approximately 19 dB and high isolation of 33.6 dB can also be achieved.

“…Embedded loop radiator [9], spline-edged bow-tie dipole [10], combination of hollow quadrant and arrow-headed patch [11], and dipole with folded metallic plates [12] were utilized as radiators to obtain impedance bandwidths of 51% (S 11 < −15 dB), 68% (VSWR < 1.5), 48% (S 11 < −15 dB), and 92% (S 11 < −10 dB), respectively. Magneto-electric dipole antennas were also applied for dual polarizations in [13] and [14] with impedance bandwidths of 65.9% (VSWR < 2) and 18.5% (S dd11 < −15 dB). Dual-polarized multidipole antenna presented in [15] and [16] achieved impedance bandwidths of 56.6% (VSWR < 1.5) and 70% (S 11 < −10 dB).…”

Compact and Wideband Differentially Fed Dual-Polarized Antenna With High Common-Mode Suppression

et al. 2019

View full text Add to dashboard Cite

A compact and wideband differentially fed dual-polarized antenna with high common-mode suppression is investigated in this paper. A square patch with crossed-slot consisting of four slant funnelshaped slots is used as the radiator, generating slant ±45 • linear polarizations. Two orthogonal placed baluns, each connected with two open-end stubs, act as the feeding network. Under differential-mode (DM) excitation, the resonating mode of the square patch and quarter-wavelength mode of the funnel-shaped slots can be excited at low and high frequency band, respectively, which enhances the operation bandwidth of the designed antenna. By using differential excitation, a high level of common-mode (CM) suppression can be realized. To verify the design, the prototype of the designed antenna and an antenna array consisting of four elements are fabricated and measured. The experimental results indicate that a DM reflection coefficient better than −15 dB and a CM suppression level better than 1 dB are achieved within a wide impedance bandwidth of 55.3% (1.66 to 2.93 GHz). A high isolation and a stable radiation pattern can be observed within the operating band. Besides, the proposed antenna maintains a small aperture size of 0.36λ 0 ×0.36λ 0 , where λ 0 is the free-space wavelength at the center frequency of operation band. INDEX TERMS Common-mode suppression, differentially fed, dual-polarized antenna, multi-mode, slot antenna, wideband antenna.
