Performance improvement of microstrip patch antenna using a novel double‐layer concentric rings metaplate for 5G millimeter wave applications

Abstract

This paper presents the performance improvement of a microstrip patch antenna (MPA) using a novel double-layer concentric rings metaplate (DLCRM) for fifth-generation (5G) millimeter wave (mmWave) applications. To improve the performance of the proposed antenna, a DLCRM is placed above the MPA having an air gap. The design procedure is explained using the different shapes of DLCRM, and the double negative (DNG) characteristic of metamaterial is verified. Moreover, the effects of the DLCRM on the MPA are validated by experimental results. The proposed antenna attains a high-gain of 11.59 dBi and has an impedance bandwidth from 27.1 GHz to 29.56 GHz (8.68%) which is the potential 5G mmWave band. The measurement result shows that the bandwidth of the antenna is improved by 2.04%, and broadside gain is increased by 4.69 dBi compared to the MPA without a DLCRM. Thus, the antenna provides high gains with wide bandwidth that makes it a suitable candidate for 5G mmWave applications.

A New mm-Wave Antenna Array with Wideband Characteristics for Next Generation Communication Systems

“…These antenna arrays include higher numbers of radiating elements with low-loss feeding networks [7,8]. There are several antenna systems reported in the literature [9][10][11][12][13][14][15]. These antenna systems include substrate integrated waveguide (SIW) antenna systems, air filled gap structures (AFGs), and planar structures.…”

“…The reported antenna showed a peak gain of 7 dBi, but the bandwidth at both resonances is extremely low. Metamaterial-induced mm-wave antennas have also been reported, but they are difficult to assemble and the cost and complexity generally increase [14,15].…”

A design of high‐gain array antenna with novel metamaterial structures for millimeter‐wave femtocell implementation

“…It is worth noting that the size of this antenna and the previous one is 0.047 λ g 3 . These dimensions make the proposed antenna a suitable option for femtocell networks 1 …”

“…The fifth‐generation mobile (5G) is currently one of the newest generations of mobile communications systems, which are defined in the millimeter‐wave frequency band 1 . This generation, which was introduced as a result of the demand for high transmission rates in communications, promises that the data transmission rate will reach more than 1 Gb/s 2 .…”

“…This generation, which was introduced as a result of the demand for high transmission rates in communications, promises that the data transmission rate will reach more than 1 Gb/s 2 . Low latency and very high transmission rates are among the advantages of this generation of wireless communication networks 1 . However, this high transmission rate requires the availability of large frequency bandwidth.…”
