“…Decoupling can also be achieved by inserting a neutralization line into antenna elements [9]. Dual polarization is another efficient method to realize decoupling and enhance reliability in the wireless communication system [10][11][12]. At the same time, although the Federal Communications Commission (FCC) allowed commercial use of the UWB band of 3.1-10.6 GHz, there are other narrowband communication systems, such as the IEEE 802.11 wireless local area network (WLAN) centred at 5.5 GHz, which may cause possible electromagnetic interference to the UWB applications.…”

Abstract-A novel uniplanar compact WLAN band-notched printed ultra wideband (UWB) multiple-input multiple-output (MIMO) antenna with dual polarization for high data-rate wireless communication is proposed. The antenna consists of two CPW-fed floral radiating elements along with a decoupling structure to ensure high isolation. The band notch at the WLAN frequency band is achieved by etching one single U-shaped slot on each antenna element. Results show that the proposed antenna gives impedance bandwidth from 2.7 GHz to 10.9 GHz with notched frequency band from 5.1 GHz to 5.9 GHz. The proposed antenna provides nearly omnidirectional radiation pattern, low envelope correction coefficient [ECC], moderate gain, efficiency, fidelity factor and pattern stability factor [PSF]. Furthermore, diversity characteristics such as mean effective gain [MEG] and diversity gain [DG] are also studied. Moreover, the time-domain analysis displays minimum dispersion to the radiated pulse. All these features make the proposed antenna a good candidate for future high data-rate wireless communication systems with polarization-diversity operation, where the challenge of multipath fading is a major concern.

Abstract-A low-profile broadband dual-polarized antenna with high isolation and low cross polarization is presented in this letter. The proposed antenna employs two different feeding mechanisms. On one hand, two out-of-phase probes loaded with two small circular patches make the proposed antenna operate in horizontal mode. On the other hand, two pins connecting two eyebrow-shaped patches and the ground form a magnetic loop which enables the proposed antenna to achieve vertical polarization. By elaborately adjusting the feeding structures, measurements demonstrate that the proposed antenna not only achieves 10-dB return loss bandwidths of 49% (1.7-2.8 GHz) and 28% (2-2.65 GHz) for port 1 and port 2, respectively, but also maintains a high isolation better than 32 dB over the entire common frequency band. Meanwhile, within the main lobes, the cross polarization levels, both in E-plane and in H-plane, stay lower than −25 dB for port 1 and −20 dB for port 2. In addition, the proposed antenna with a profile of 0.13λ 0 achieves the maximum gains of 8.4 dBi for horizontal polarization and 8.2 dBi for vertical polarization.

“…Several studies on investigating the dual-polarized antennas with different radiating structures, such as patch antennas and slot antennas, can be found in the literatures [10][11][12][13]. Among them, the radiation patterns are unidirectional [10,11] or bidirectional [12,13].…”

“…Among them, the radiation patterns are unidirectional [10,11] or bidirectional [12,13]. However, in some special conditions, it is requisite for the antennas to have omnidirectional radiation patterns to cover a large service area, such as the portable access points or base stations.…”

Abstract-An omnidirectional dual-polarized slot antenna with high port isolation for 2.4-GHz wireless local area network (WLAN) applications is proposed in this paper. The omnidirectional radiation patterns of the vertical polarization (VP) and horizontal polarization (HP) are achieved by individually cutting two orthogonal slots onto the metal walls of a cuboid antenna. The overall volume of the compact antenna is only 60 × 10 × 10 mm 3 (0.488λ 0 × 0.081λ 0 × 0.081λ 0 ). A prototype of the designed antenna is manufactured and tested. Both simulated and measured results show that the −10 dB impedance bandwidths of dual polarizations cover the desired band of 2.4-2.484 GHz and the port isolation, in the operating frequency, is less than −35 dB. Stable measured gains are greater than 2.75 and 1.35 dBi for the VP and HP, respectively.
