“…However, this research offers agility from 2.45 to 3.5 GHz along with bandwidth reconfiguration. The tunability is also lesser for 17,19 While most of the research has concentrated on the design of antennas for access points, this research has directly targeted the development of an antenna for the automotive environment. …”

SummaryA reconfigurable MIMO antenna for heterogeneous vehicular networks is reported in this paper. The frequency and bandwidth characteristics of the MIMO antenna can be reconfigured to meet multi‐standard and multi‐frequency requirements in automobiles. The antenna element evolved from an edge‐chamfered ultra‐wideband (UWB) antenna operating from 2.1 to >15 GHz. The bandwidth reconfiguration is achieved through the selection of excitation paths connecting the feed and radiator. The feedline selection is performed using PIN diodes, making the antenna operate in three distinct modes, namely, UWB mode (Mode 1: 2.1–>15 GHz), industrial, scientific and medical/Internet of Things (ISM/IoT) mode (Mode 2: 2.45 GHz), and wireless local area network (WLAN) mode (Mode 3: 5–6 GHz). The feed path corresponding to Mode 2 and Mode 3 is incorporated with a suitable filtering network to shape the frequency response of the antenna based on the user's requirements. Owing to the requirement of cognitive selection of frequency bands, the frequency tunability in Mode 2 is realized using varactor diodes. The varactor‐incorporated feed path reconfigures the center frequency between 2.45 and 3.5 GHz. The proposed MIMO antenna offers gain and total efficiency greater than 2.94 dBi and 76%, respectively. The prototype of the 4‐port MIMO antenna is being fabricated to test its functionality in real time.

“…Another way to a polarization reconfigurable antenna is to apply a phase-shift feeding network. [13][14][15][16][17][18] For this method, a wideband phase-shift network is tough to achieve. Additionally, it would use numerous lumped components, deteriorating the radiation performance.…”

“…Additionally, it would use numerous lumped components, deteriorating the radiation performance. In Sun et al 15 and Kang et al, 18 quad‐polarization diversities antennas are proposed with an operating bandwidth of 17% and 10%, respectively.

In this letter, a wideband and low‐profile multipolarization reconfigurable antenna based on metasurface (MTS) is proposed. The antenna mainly contains two parts, an upper layer of MTS and a bottom layer of circular slot antenna. The MTS acts as a polarization controller, by mechanically rotating the MTS layer at a proper angle while keeping the circular slot antenna remain stationary, the polarization mode of the antenna can be switched to linear polarization (LP), left‐hand circular polarization (LHCP), and right‐hand circular polarization (RHCP). The experimented −10 dB impedance bandwidth of 37.8% and 54% for LP and circular polarization (CP) modes, respectively. The measured overlapped 3‐dB AR bandwidth is 22.2% for both CP modes, covering from 3.2 to 4 GHz. Moreover, the measured peak gain of the presented antenna reaches 9 dBi and 8 dBic for LP and CP modes, with a lower profile of 0.05 λ0.

“…Multi‐polarization and pattern reconfigurable antennas generally possess more than two polarization modes, and they can switch the work state according to the communication requirement. There have three common approaches to realizing a polarization reconfigurable antenna, one is to reconfigure the radiator by some radio frequency (RF) switches [2–4], another one is to design a phase‐shift network [5–7], and the other is to utilize the metasurface (MS) [8–10]. A ±45° polarization reconfigurable antenna proposed in [2] has a low profile of 0.04 λ , but a narrow operating bandwidth of 5.7%.…”

In this letter, a low‐profile metasurface (MS) antenna with multi‐polarization and pattern reconfigurability is presented. The antenna mainly consists of two parts, including a loop antenna fed by balun, and a MS antenna excited by the coupled aperture. When switching the PIN diode and rotating the MS, the multi‐polarization and pattern reconfigurable ability of the antenna is obtained. While the loop antenna is excited, a horizontally linear polarized (HLP) wave and omnidirectional pattern are obtained. Besides, when the MS is operated, due to the differential phase between the orthogonal surface impedance components, the antenna can be switched between vertical linear polarization (VLP), left‐hand circular polarization (LHCP), and right‐hand circular polarization (RHCP). Furthermore, the antenna could achieve a directional pattern. As the simulated and measured results shown, the proposed antenna has an overlapped impedance bandwidth (IMBW) of 24.7% for all polarization modes and a 3‐dB axial ratio (AR) bandwidth of 11.8% for L/RHCP modes. Moreover, the antenna owns a low profile of 0.06 λ (under the operating centre frequency).
