“…Planar UWB monopole antenna with two back‐to‐back tapered slots presented in Reference is estimated to offer good MIMO performance. In Reference , a two‐element Yagi antenna is reported for ISM and WLAN frequency bands. The reported antenna offers considerable size reduction with the exploitation of loop‐based driver element and achieves good MIMO performance.…”

This article presents the design, fabrication, and testing of a broadband directional slot antenna and its application in a vehicular environment. The proposed antenna consists of a slot antenna fed by a simple microstrip line. Broadband impedance matching is achieved by replacing the conventional microstrip line with a modified microstrip line. The modified microstrip line consists of a microstrip line terminated with an impedance transformer and a square patch. The proposed antenna offers 76.9% bandwidth centered around 4.8 GHz covering most of the communication applications between 3 and 6.75 GHz. Furthermore, the antenna's radiation pattern is shaped to obtain the desired directional characteristics using a simple reflector and array of via holes. The typical gain enhancement is 2.45 dBi at 5 GHz. This gain enhanced slot antenna is further used to construct the four‐element MIMO antenna. The proposed MIMO antenna configuration offers omnidirectional coverage with realized antenna gain greater than 6 dBi making the antenna more suitable for the vehicular environment. The prototype antenna and the MIMO array are fabricated and measurement results are presented. The measurement results are in good agreement with the simulation results.

“…Although this antenna has relatively simple feeding structure, it has much reduced BW. To enhance BW with reduced size, a loop driven and folded dipole PQYA were designed. In Reference , compact monopole‐driven PQYA is proposed.…”

In this study, a new configuration of a low profile, broadband printed quasi‐Yagi antenna with two directly fed monopoles has been proposed. The property of a printed monopole antenna with a simple microstrip feed‐line has been used to simplify feeding structure of the printed quasi‐Yagi antenna. A broad bandwidth is achieved by cascading another monopole element of different lengths in a series to obtain two nearby resonances. The proposed antenna consists of two driven monopoles on one side of the dielectric substrate, whereas, on the other side, a reflector and a director are realized as parasitic monopole elements, directly on the ground plane. The measured impedance bandwidth of 70.2% (1.46‐3.05 GHz) with stable gain ranging from 4.7 to 5.3 dBi in the entire bandwidth has been achieved. The antenna has the front‐to‐back ratio better than 10 dB and cross‐polarization level below −20 dB in the direction of maximum radiation over the entire bandwidth. The simulated performance of the antenna has been experimentally verified with good agreement.

“…This can be achieved by polarization diversity or by increasing the space between the antennas [8]. Crosspolarized antenna geometries are usually complicated in design, whereas increasing the space between the antennas results in larger volumes [10]. For implementation of the UWB MIMO systems, some good methods are radiation pattern diversity, space diversity, and polarization diversity.…”

This paper presents a novel compact 2 × 2 planar MIMO antenna system with ultra-wide band capability. Antenna system is specifically designed to target lower 5th generation operating bands ranging from 2 GHz to 12 GHz. This band also covers the IEEE 802.11 a/b/g/n/ac. The antenna array geometry has been simulated using CST MWS. The design is extremely miniaturized with total structure size of 13 × 25 × 0.254 mm 3 . The simulated and measured results have been presented. Measured and simulated return loss values for designed antenna are less than −10 dB over the operating band and lowest values of −35 dB and −32.5 dB can been seen at 5.2 GHz and 9.2 GHz, respectively, whereas at the center frequency the return loss is −25.2 dB. The mutual coupling between both elements is less than −20 dB over the transmission bandwidth. Simulated and measured radiation patterns in E and H planes at center frequency show nearly isotropic far fields. The maximum gain is measured as 4.8 dB. Promising results of Envelope Correlation Coefficient and gain diversity of the design have been achieved. Simulated and measured results are found in good agreement. The fractional bandwidth of antenna is measured as 143.2% which satisfies its ultra-wide band response.
