“…With the development of the wireless communication, the requirement of the bandwidth of the antenna for the base station applications becomes more and more wide. This trend is so clear from its development process; the bands of 690-960MHz and the 1710-1850MHz were used for the 2G systems, and the band was broadened to be 265MHz from 1880 to 2145MHz for 3G communication, and then the wider bands of both the 1745-1900 MHz and the 2300MHz-2655MHz were developed for 4G systems [1][2][3]. Nowadays, to integrate easily, the antenna covering all the bands of 2G/3G/4G has attracted researchers' interest which should have the bands 32% (690-960MHz) and 45% (1710.…”

A new dual-broadband printed dipole antenna for base station applications is proposed in this communication. This antenna has three different dipoles with the same feed point and an extra parasitic strip. The two arms of the three dipoles are printed on opposite sides of the substrate and symmetrical on the centerline, but the parasitic strip at the end of the dipole is just put on one side. Besides, a U-shaped reflector is designed at the bottom of the antenna to realize good radiation characteristics in the working frequency. The simulated and measured results show good agreement. The two studied bands are both broadened which, respectively, achieve 36.7% (690–1000MHz) and 47.3% (1710–2770MHz) for the lower and higher bands so as to satisfy the 2G/3G/4G wireless communication, and the corresponding gains of 4-5dBi and 5-6dBi are also obtained.

“…Currently, piles of wideband dual-polarized antennas have been proposed in [2][3][4][5][6][7][8][9][10][11][12][13]. Cross dipole antennas in [2][3][4][5] and patch antennas in [6][7][8] are two classic wideband antenna types. In the design of [9], a dual-polarized antenna with wide operating band, high port isolation and good radiation performances is proposed by loading some dipoles.…”

In this paper, a wideband ±45 • dual-polarized antenna is proposed for the wireless communication. An annular ring patch with four arc-shaped slots is employed to generate a wide operating impedance bandwidth. By introducing four open stubs to the antenna element, the impedance bandwidth is enhanced. The antenna has a broad impedance bandwidth (VSWR < 2) of 51.2% (1.63-2.75 GHz) and a high port-to-port isolation of 27 dB over the entire band of operation. In addition, a 1 × 4 antenna array is developed for the wireless communication. Experimental results illustrate that the antenna array features wide operational bandwidth, high port isolation and superior radiation performance.

This paper presents a hybrid ring feeding dual-polarized patch antenna with high isolation in a wide working band. The proposed antenna consists of a circular radiating patch printed on the upper horizontal substrate, two pairs of Γ shaped strips printed on two vertical substrates, and a hybrid ring feeding network printed on the lower two horizontal substrates. The proposed antenna adopts Γ shape strips coupled feeding structure to achieve a wide operating band. Furthermore, a hybrid ring feeding structure with high isolation in a wide bandwidth, which is firstly proposed, is applied as feeding network. When one port is excited, the feeding network can realize twice the power cancellation. Thus, high ports isolation characteristics can be obtained. A prototype of the proposed antenna is fabricated and measured. Measured results show that the 10 dB reflection coefficient bandwidths of the two ports are both about 38.7%, with port isolation higher than 40 dB through most of the band, and the cross-polarizations are below −24 dB.
