“…Patch antenna is a good choice for base station antennas, due to its attractive features such as light weight, low costs, and easy fabrication for dual-polarization implementation. The patch antenna type has already been studied a lot [2][3][4][5][6][7], but wide impedance bandwidth is very difficult to be achieved with these antennas.…”

Abstract-A novel broadband dual-polarized magneto-electric (ME) dipole antenna is proposed for 2G/3G/LTE/WiMAX applications. The proposed antenna has stair-shaped feeding strips to impart a wide impedance bandwidth to it and a rectangular box-shaped reflector to enhance its stability in radiation patterns and high gain over the operating frequencies. The measured results show that a common impedance bandwidth is 80% with standing-wave ratio (SWR) ≤ 1.5 from 1.68 to 3.92 GHz, and port-to-port isolation larger than 25 dB within the bandwidth. The measured antenna gains vary from 9.2 to 12 dBi and from 9.2 to 11.8 dBi for port 1 and port 2, respectively. The antenna has nearly symmetrical radiation patterns with low back-lobe radiation both in horizontal and vertical planes, and broadside radiation patterns with narrow beam can also be obtained.

“…Meanwhile, they can also achieve a wider bandwidth with simpler structure compared with dual-polarized patch/slot antennas [2]. In order to further improve the impedance bandwidth of the dual-polarized dipole antennas, many efforts have been done [3][4][5], while very few attention has been paid on optimizing the dimension of the dual-polarized dipole antennas for base station have been reported, especially for those printed dipole antennas [6][7][8], which are commonly used in industry due to their outstanding features in terms of simple structure, light weight and low cost, but good performance.…”

Abstract-A novel compact wideband dual-polarized printed dipole antenna for base station application is presented. The proposed antenna is composed of four assembled substrates. Two pairs of identical arrow-shaped conductive lines on the tophat substrate form two orthogonal polarized dipoles. Two baluns connected with 50 Ω coaxial cables are integrated on another two vertical substrates to excite the dipoles. The other horizontal board at bottom provides grounding. A rectangular boxshaped reflector is also used to enhance its stability in radiation patterns over the operating frequencies. It achieves 22% size reduction from the conventional printed half-wavelength cross-dipole, and 43.2% impedance bandwidth (VSWR < 2), while maintaining a stable radiation pattern with measured CrossPolarization Degradation (XPD) better than −22 dB at boresight and an average peak gain of 8.4 dBi for a 65 • Azimuth Beamwidth base station application at 700/800/900 MHz bands. With the scalable miniature structure, it may also find itself suitable for side-by-side multiband Multi-Input Multi-Output (MIMO) or Large-Scale Antenna (LSA) 5G base station applications. A 4 × 4 array prototype of the LSA is also designed and fabricated, and it achieves 27.8% impedance bandwidth (VSWR < 1.5) with well decorrelated element performance and array XPD better than −20 dB across as large as 30 • tilting range.

“…To satisfy the demand of European Digital Dividend (791 ∼ 862 MHz), CDMA800 (825 ∼ 880 MHz), and GSM900 (889 ∼ 960 MHz) simultaneously, the dual-polarized antenna should cover the bandwidth of 790 ∼ 960 MHz. Although many kinds of base station antennas have been proposed in [2][3][4][5][6][7][8][9][10][11][12][13][14], there are still some improvements should be made. Some of these antennas [2,7,8] have a narrow impedance bandwidth that cannot cover the bandwidth from 790 MHz to 960 MHz.…”

Abstract-A compact dual-polarized antenna element integrated with balun is proposed. Two pairs of dipoles are employed for the dual-polarizations of the antenna, and strong mutual coupling between them is introduced to widen the bandwidth of the antenna. Bent dipoles are used to reduce the size of the antenna. The simulated and measured results show that the proposed antenna can cover the bandwidth ranging from 790 MHz to 960 MHz with VSWR < 1.5 and isolation > 26 dB. The antenna element is also fabricated and tested. The measured results show that the antenna can be a good candidate for the design of European Digital Dividend/CDMA800/GSM900 mobile communication base station antenna.
