“…To address the advantages of the proposed antenna, the performances of some other reported filtering antennas are tabulated in Table 1 for comparison. Compared with these MIMO filtering antennas proposed in References 12‐15, this work can realize a wide bandwidth and a low cross polarization. Compared with those in References 13 and 14, this work can realize a high element gain.…”

A novel compact MIMO dual‐mode filtering antenna array with wide bandwidth, high selectivity and good isolation is proposed. The filtering antenna unit consists of a patch radiator at the top layer coupled with a high‐order dual‐mode filter at the bottom layer through a rectangular slot in the middle ground layer. The fourth‐order filter adopts two E‐shape dual‐mode resonators to achieve wide bandwidth and high selectivity. A pair of filtering antenna units form a MIMO array with a distance of 0.2λg by using three interdigital lines in the middle to enhance the port isolation. Finally, a 1 × 2 MIMO filtering antenna array operating at 2.45 GHz is designed and fabricated, which shows wide fractional bandwidth of 24.5%, sharp skirt slope with a pair of radiation nulls, smooth realized gain of 4.5 dBi as well as high isolation more than 20 dB.

A new dual‐band bandpass filter (BPF) using two very simple coupled microstrip rings is proposed in this paper. The two identical 3λg/2 microstrip rings are coupled each other with λg/2 coupled length, resulting in the generation of dual frequency bands with multiple transmission zeros (TZs). Theoretical deduction is presented to verify the proposed structure. The center frequencies and bandwidths of the two passbands can be tuned by controlling the impedance parameters of the microstrip rings. For demonstration, a prototype example of this dual‐band BPF is fabricated and characterized. The measured results show that it has high selectivity and great return losses of passbands with multiple TZs at the stopband.

“…While multiple antennas of different frequency bands can be integrated into a fixed volume model, it is significant to reduce the coupling between the antennas and improve the radiation efficiency [9]. The literature [10] presents a new decoupling and matching network design for symmetric, single-and dual-band two-element antenna arrays. A multi-functional microstrip-fed ultra-wideband monopole antenna with two dual-mode resonators and shunt metallic strips has been presented, which two additional operational states are created [11].…”

The Internet of vehicles (IoV) is an important part of mobile communication system with the development of Internet of things (IoT). A novel multiband automobile antenna is proposed, which can cover all frequency bands for the long-term evolution (LTE), the 5th generation wireless systems (5G), the wireless local area network (WLAN) and the dedicated short-range communication (DSRC) (from 690 MHz to 944 MHz and from 1.46 GHz to 6 GHz). The antenna is designed based on the monopole antenna, and the impedance matching performance of the antenna is improved by loading the toothed capacitor and the impedance matching disc. The simulation results show that the automobile antenna achieves good impedance matching in the working bandwidth and obtains omnidirectional radiation pattern in the horizontal direction. The electric field distribution of the antenna placed on the vehicle roof is simulated to evaluate the network performance of the antenna system in the urban environment. The transmission coefficient of the transceiver system using the automobile antenna is also analyzed based on the electromagnetic simulation results and statistical model. The blind area of mobile communication system is effectively covered with the automobile antenna, which could be used to connect the LTE cell and the IoV system.
