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.

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.

This paper presents a low loss fully embedded bandpass filter (BPF) using low temperature co-fired ceramic (LTCC) for multilayer System-in-Package (SiP) and Multi-Chip-Module (MCM) applications, e.g. wireless applications for the unlicensed 60 GHz band. The measured insertion loss was 1.5 dB at the center frequency 58 GHz, and a return loss of less than −10 dB was achieved, including two grounded coplanar waveguide transmission line (CPWg) to stripline transitions. The four layers BPF has a 3 dB bandwidth of about 11 GHz which supplies e.g. broadband and high data rate applications. The whole BPF requires a substrate area of 5.6 × 2.1 × 0.42 mm3 with transitions and a shielding via fence. This BPF suits well for V-band applications in a LTCC package because of the compact dimensions and the good performance.

The electromagnetic (EM) imaging technique at mm-band 60 GHz is proposed for data encoding purpose in the chipless Radio Frequency Identification (RFID) systems. The fully printable chipless RFID tag comprises tiny conductive EM polarizers to create high cross-polar radar cross-section. Synthetic aperture radar approach is applied for formation of the tag's EM-image and revealing the tag's content. The achieved high data encoding capacity of 2 bits/cm2in this technique based on a fully printable tag is very convincing for many applications. The system immunity to multipath interference, bending effect, and printing inaccuracy suggests huge potentials for low-cost item tagging. Tags are also readable through a tick paper envelop; hence secure identification is provided by the proposed technique.
