This paper proposes a novel radiation pattern reconfigurable antenna for 5G (Fifth Generation) applications. A rectangular patch is enclosed by a hollow rectangular radiating structure. The patch is connected to the rectangular structure by two switches SW1 and SW2, which will, in turn, provide three different radiation patterns, Modes, depending on the ON and OFF states of the switches. When SW1 is OFF and SW2 is ON, Mode 1, pattern radiates in a direction with an angle of 38o. While SW1 is ON and SW2 is OFF, Mode 2, the pattern radiates in the radiating plane, exactly opposite to Mode 1, with an angle of -38o. In Mode 3, the pattern is directed simultaneously towards the angles of ±41o; for this case, both switches, SW1 and SW2, are turned OFF. The proposed design resonates in the constant 38GHz frequency range which is useful for 5G broadband cellular communication networks. And this design can also be used for 60 GHz resonant frequency with certain adjustments. Additionally, the return loss is -31.5 to -42.5, while directivity is from 5.69-6.76dB, and gain lies in the range of 5.4- to 6.4dBi. Moreover, Voltage Standing Wave Ratio, VSWR, varies from 1.01 to 1.05. The size of the antenna is 3.34x6.73mm2 which is mounted on a 0.381 mm thick, Roger RT5880 having a relative permittivity of 2.2. Central Standard Time, (CST) microwave studio software is used for simulating the design. The miniscule size, a smaller value of the return loss, an ideal value of VSWR with a reasonable value of directivity and gain make the proposed design best for future 5G mobile communications.

Nowadays, most antenna researchers over the world are focusing on the design of the antenna for the fifth generation (5G) application (indoor and outdoor). High intensive research on 60 GHz antenna for high data rate indoor communication is becoming a trending topic. The high propagation loss at this band is the most challenging. The antenna needs to have higher gain to overcome the loss. Such antenna designs have been proposed recently. This paper, a new MIMO 2x4 patch rectangular antenna operating at 60 GHz is designed for Wi-Gig application. The rectangular patch antenna has 1.75 mm x 1.54 mm of size, printed on Rogers Duroid RT 5880 substrate, the dielectric constant of 2.20 and loss tangent of 0,0009. The antenna was designed and simulated using CST simulation software.  The simulated return loss showed a very consistent characteristic. The return loss reached −30 dB at 60 GHz.  The broad bandwidth obtained is 4.3 GHz concerning -10 dB. The omnidirectional radiation pattern with 13.4 dBi of gain is obtained. This antenna meets the Wi-Gig requirement.

5G Mobile Communications

The design of compact dual band grid array antenna (GAA) designed on FR-4 substrate for future Fifth Generation (5G) Mobile Communications at 10 GHz is reported. The proposed antenna uses coaxial technique of feeding and has a dimension of 48 mm × 55 mm × 1.6 mm. Simulation results using CST microwave studio illustrates that the antenna has a band from 10.03 GHz to 10.68 GHz and another band from 10.7 GHz to 12.23 GHz. This excludes the 10.68 – 10.7 GHz band in which emissions were forbidden by the Radio Regulations in the sense that it has been allocated for the Radio Astronomy, Space Research and Earth Exploration Satellite (passive). The antenna has a maximum gain of 8.03 dBi at 10 GHz, thus a good candidate for the future 5G mobile communications.

This paper presents different reconfigurable antennas with frequency, polarization, and pattern diversities. All the antennas have a very simple, novel, and compact structures, which are used for different wireless communication applications. These antennas employ switching for obtaining different reconfigurations. At first, an E-shaped antenna is designed for multi-band frequency reconfigurability. Second, circular and rectangular-shaped patch antennas are designed for achieving diversity in polarization. At last, a pattern reconfigurable antenna is designed with multiport excitation. These antenna performances are analyzed using various parameters such as return loss, radiation pattern, voltage standing wave ratio (VSWR), and gain. The prototypes of the antennas are fabricated and measured results along with simulated ones are presented. Both the results are in good agreement.
