An array that consists of eight such antenna elements is designed, fabricated, and measured. Results show that the voltage standing wave ratio (VSWR) is less than two over the whole operating band for all ports. For the radiation characteristics, boresight gain ranging from 5.3 to 8.8 dBi is achieved for each antenna element, and when it comes to the array, a peak gain of 17.23 dBi occurs at 4 GHz when all the antenna elements are excited with identical amplitude and phase. Beam scanning is also realized in the whole operating band through phase disposing, and the scanning range is up to ±45° from 1 to 2 GHz and ±30° from 2 to 5 GHz. 

Ultrawideband Compact Magnetoelectric Dipole Antenna/Array With Dual-Polarization

The escalating trend toward high integration in wireless systems underscores the pivotal importance of antennas with wide bandwidth and compact sizes. In this letter, a compact ultrawideband (UWB) dual-polarized antenna is proposed with a remarkable bandwidth, which can basically cover the <italic>S</italic>, <italic>C</italic>, and <italic>X</italic> bands. To realize the UWB operation, this design harnesses the UWB principle of tightly coupled arrays, thereby facilitating bandwidth expansion. Moreover, to achieve optimal compactness in electrical sizes, our design mitigates the edge effect through the implementation of edge-coupled patches and shorting vias. An ultrawide impedance bandwidth of 135.7% ranging from 2.3 GHz to 12 GHz with voltage standing-wave ratio (VSWR) < 2.5 (<inline-formula><tex-math notation="LaTeX">$\vert$</tex-math></inline-formula><italic>S</italic><inline-formula><tex-math notation="LaTeX">$_{11}$</tex-math></inline-formula><inline-formula><tex-math notation="LaTeX">$\vert$</tex-math></inline-formula> < −7.3 dB) is observed. Notably, the configuration of the antenna is exceedingly compact, measuring merely 0.18<inline-formula><tex-math notation="LaTeX">$\lambda _{L}\times 0.18\lambda _{L}\times$</tex-math></inline-formula> 0.09<inline-formula><tex-math notation="LaTeX">$\lambda _{L}$</tex-math></inline-formula>, where <inline-formula><tex-math notation="LaTeX">$\lambda _{L}$</tex-math></inline-formula> denotes the wavelength at the lowest operating frequency. Due to the attractive advantages of UWB and compact sizes, our proposed antenna emerges as a promising candidate for integration as radiation elements in UWB highly integrated wireless systems.

A new ultra-wideband magnetoelectric (ME) dipole antenna is proposed as a dual-polarized base station antenna for 3G, LTE and Sub-6GHz 5G wireless networks. Double layers of ME dipoles with different sizes are combined to expand the bandwidth, and the orthogonal placement of ME dipoles enables dual polarization radiation. Simulation results reveal that the proposed base station antenna achieves 133.3% fractional bandwidth and satisfying radiation characteristics, including high front-to-back ratio (FBR) (>14 dB), high cross-polarization levels (>20 dB), and stable gains about 5-10 dBi in 1-5GHz.
