“…With the development of mobile communication, 2G/3G/4G/5G mobile communication systems will be commercially available for a long time. As a result, it is essential for base station antennas to service multiple systems, 1,2 such as GSM850 (824–894 GHz), GSM900 (890–960 MHz), LTE700 (698–862 MHz), and 5G 700 (703–803 MHz) for the lower frequency mobile communications, as well as GSM 1800 (1710–1920 MHz), TD‐SCDMA/WCDMA/CDMA2000 (1880–2170 MHz), LTE2300/2600 (2300–2690 MHz), and 5G 2600 (2515–2675 MHz) for the higher frequency mobile communications. To support all the systems mentioned above, a base station antenna, which has dual wide bandwidths of 31.6% (698–960 MHz) and 44.5% (1710–2690 MHz), is required.…”

A dual‐wideband magnetoelectric dipole antenna is proposed. The magnetoelectric dipole is fed by a hook‐shaped metal sheet. To increase the gain at the upper band, the radiation arm of the electric dipole is designed in stepped shape. To widen the impedance bandwidth of the lower band, stepped‐shaped metal walls are employed and placed along the edges of the ground plane. To further improve and stabilize the higher band gain, four parasitic umbrella‐shaped metals are utilized. By using this novel scheme, a magnetoelectric dipole antenna with dual‐wideband operation is designed. It introduces two wide bandwidths of 35.3% (0.698–1 GHz) for the lower band and 63% (1.52–2.9 GHz) for the upper band. The lower‐band gain is stabilized within 7.3 ± 0.6 dBi, while the upper‐band gain is stabilized within 9.2 ± 0.8 dBi. The antenna dimension is only 0.41λL × 0.41λL × 0.1λL (λL denotes the wavelength at 0.698 GHz in vacuum).

In this article, a radiation pattern reconfigurable antenna (RPR antenna) based on the complementary source principle is proposed for automobile communication. This antenna achieves four end-fire radiation patterns in four directions by controlling the operating states of PIN-diodes. The structure of this center-fed antenna includes a corners-shorted patch and four parasitic monopoles with eight PIN-diodes to control the states of monopole antennas. The monopole antenna works as an electric current source while the center-fed patch antenna can be equivalent to in-phase magnetic currents at its periphery due to the existence of the loaded monopole. Then the radiation mechanism of the RPR antenna can be explained as a pair of orthogonal magnetic and electric current sources. As a result, four end-fire radiation patterns can be obtained by changing OFF/ON states of PIN-diodes and this antenna can be applied for high-resolution omnidirectional coverage by switching among four modes. To verify the simulation, an example antenna is fabricated and measured. The measured result exhibits a À10-dB impedance band of 3.21-3.73 GHz with a maximum realized gain of 7.07 dBi.Results show that this antenna is suitable for automobile 5G communication.

The intensive research in the fifth generation (5G) technology is a clear indication of technological revolution to meet the ever-increasing demand and needs for high speed communication as well as Internet of Thing (IoT) based applications. The timely upgradation in 5G technology standards is released by third generation partnership project (3GPP) which enables the researchers to refine the research objectives and contribute towards the development. The 5G technology will be supported by not only smartphones but also different IoT devices to provide different services like smart building, smart city, and many more which will require a 5G antenna with low latency, low path loss, and stable radiation pattern. This paper provides a comprehensive study of different antenna designs considering various 5G antenna design aspects like compactness, efficiency, isolation, etc. This review paper elaborates the state-of-the-art research on the different types of antennas with their performance enhancement techniques for 5G technology in recent years. Also, this paper precisely covers 5G specifications and categorization of antennas followed by a comparative analysis of different antenna designs. Till now, many 5G antenna designs have been proposed by the different researchers, but an exhaustive review of different types of 5G antenna with their performance enhancement method is not yet done. So, in this paper, we have attempted to explore the different types of 5G antenna designs, their performance enhancement techniques, comparison, and future breakthroughs in a holistic way.
