“…It can be seen from the Fig. 2(a) that the measured S-parameters of the antenna cover the 1.7-2.1 GHz band under -15.5 dB (VSWR<1.4) impedance bandwidth, which makes it suitable for base stations [12][13]. Moreover, the isolation (<-35 dB) between the two antenna elements has also been measured for both the antenna elements and is plotted in Fig.…”

A novel antenna with both horizontal and vertical polarizations is proposed for 1.7-2.1 GHz LTE band small cell base stations. Horizontal polarization is achieved by using the vivaldi antennas at the main PCB board in azimuth plane. Whereas, the vertical polarization is obtained using the rectangular monopole with curved corners in proximity of the horizontal elements. A prototype antenna associated with 8-elements (four horizontal and four vertical) is fabricated on the FR4 substrate with the thickness of 0.2 cm and 0.12 cm for vivaldi and monopole antennas, respectively. Experimental results have validated the design procedure of the antenna with a volume of 14 x 14 x 4.5 cm 3 and indicated the realization of the requirements for the small cell base station applications.

Abstract-A wideband dual-polarized crossed-dipole antenna with parasitical crossed-strip for basestation applications is presented. By using a pair of orthogonal crossed-dipoles, two linear polarizations (±45 • ) are obtained. A parasitical crossed-strip is introduced to improve the impendence bandwidth and enhance the isolation (S 12 ) between the two orthogonal polarizations of the upper band. The antenna shows a wideband impedance characteristic about 34.9% for S 11 ≤ −10 dB (+45 • polarization) and S 22 ≤ −10 dB (−45 • polarization). High isolation (S 12 ≤ −32 dB) between the two polarizations in the required band are obtained. The stable peak gain, unidirectional radiation patterns and low crosspolarization over the whole operating band are also achieved. Due to its good performance, simple fabrication technique and low cost, the antenna is very suitable for potential base station applications in mobile communication such as DCS, PCS and UMTS.

“…The dual-polarized antenna proposed in [6] is a combination of a modified low-profile monopole and a circular planar loop and it achieves an impedance bandwidth of about 25%, being unsatisfactory to cover the LTE frequency bands. Dual-polarized wideband antennas also are proposed in [7][8][9][10][11]; however, the operating frequency bands of the proposed antennas cannot cover the 3G and LTE frequency bands. The broadband dipole antenna proposed in [12] is composed of an irregular shorted patch and planar dipole elements, which obtains a bandwidth of 49.5%.…”

A dual-polarized array with downtilted radiation patterns is proposed for wireless communication applications. The proposed dual-polarized antenna element achieves an enhanced impedance bandwidth and compact dimensions by introducing a parasitic circular patch and vertical metal cylinders, which is a good candidate for radiating elements in base station antennas. By optimizing the amplitude and phase distribution along the feed, a radiation pattern with a downtilted angle is obtained. The dual-polarized array antenna achieves an impedance bandwidth for VSWR≤1.5, covering the frequency bands for 3G/LTE systems. Moreover, the proposed array achieves high port isolation, the stable antenna gain over the entire operating band. Therefore, the proposed array antenna is very suitable for potential wireless communication applications. A prototype has been manufactured and measured. The measurements, that match the design objectives, are also presented.
