A planar miniaturized ultra‐wideband (UWB) dual‐polarization multiple‐input‐multiple‐output (MIMO) slot antenna is presented in this article. Two orthogonal microstrip lines are utilized to feed antenna, which can excite both orthogonal modes in two orthogonal‐stepped slots to realize dual‐polarization characteristics. Two orthogonal‐stepped slots are its main radiators. The overall size of the presented antenna is only 32 × 22 × 0.8 mm3. The antenna was built and measured. The measurement of common –10 dB impedance bandwidth reaches 7.56 GHz (110.7%, 3.05‐10.61 GHz). Port isolation is greater than 18 dB over the entire working band. The radiation patterns and gains are stable over the whole working band.

A new ultra-wideband (UWB) multiple-input/multiple-output (MIMO) antenna system is proposed for future smartphones. The structure of the design comprises four identical pairs of compact microstrip-fed slot antennas with polarization diversity function that are placed symmetrically at different edge corners of the smartphone mainboard. Each antenna pair consists of an open-ended circular-ring slot radiator fed by two independently semi-arc-shaped microstrip-feeding lines exhibiting the polarization diversity characteristic. Therefore, in total, the proposed smartphone antenna design contains four horizontally-polarized and four vertically-polarized elements. The characteristics of the single-element dual-polarized UWB antenna and the proposed UWB-MIMO smartphone antenna are examined while using both experimental and simulated results. An impedance bandwidth of 2.5–10.2 GHz with 121% fractional bandwidth (FBW) is achieved for each element. However, for S11 ≤ −6 dB, this value is more than 130% (2.2–11 GHz). The proposed UWB-MIMO smartphone antenna system offers good isolation, dual-polarized function, full radiation coverage, and sufficient efficiency. Besides, the calculated diversity performances of the design in terms of the envelope correlation coefficient (ECC) and total active reflection coefficient (TARC) are very low over the entire operating band.

“…As a typical VP antenna, a monopole antenna possesses omnidirectional radiation characteristic. Recently, a type of printed antenna [8][9][10][11] composed of two identical perpendicular positioned monopoles has been designed for dual-polarized omnidirectional radiation; however, the profile height is larger than 0.1λ L at the lowest operating frequency. Another type of dual-polarized omnidirectional antenna is the combination of a circular HP antenna and a VP monopole antenna.…”

A high isolation broadband dual-polarized omnidirectional antenna comprising two low profile orthogonally polarized omnidirectional radiating elements is presented. A modified monopole using loadings to broaden impedance bandwidth is applied to vertical polarization (VP), while four printed concentrically arranged Yagi-Uda-like antennas are employed for horizontal polarization (HP). Both the simulated and measured results indicate that the operating bands of the proposed antenna with its reflection coefficient less than −10 dB are 1.48 to 3.16 GHz for VP and 1.69 to 2.7 GHz for HP. A good port isolation larger than 40 dB and omnidirectional patterns with the out-of-roundness less than 2 dB in horizontal plane are obtained. This paper explains the radiation mechanism by investigating the simulated surface current distributions for VP element and establishing a radiation model for HP element, and also analyzes the performance of the proposed antenna. This antenna design can be applied to 4G (LTE) communication system.
