15 GHz grid array antenna for 5G mobile communications system

Abstract

A compact grid array antenna implemented using FR4 substrate for 5G Mobile Communications at 15 GHz is presented. The antenna with dimensions of 49 mm × 58 mm × 1.6 mm has 23 radiating elements to provide high gain. It is excited using coaxial feeding technique. Measurement of the fabricated prototype for the simulated antenna was carried out. Both measured and simulated results agree with each other. The measured result shows that the antenna has achieved an impedance bandwidth of 14% from 13.8 GHz to 15.9 GHz with a gain of 14.4 dBi at 15.9 GHz. © 2016 Wiley Periodicals, Inc.

Thermoplastic Laminate and Cordierite/Indialite Glass-Ceramic Hybrid Package for 15-GHz Operated Antennas

“…Antenna gain of 12.5 dB was measured in [11] and gain of 12.7 dB with 66% efficiency at 15 GHz in [12] emphasizing good antenna efficiency values in this study. X-band operated lens antennas performed gains of 12 dB and 18 dB, respectively in [23][24].…”

“…The SiP package consists of ceramic substrate as low loss material for antennas and at the same time good choice for further amplifier integration in the package. Hemispherical polymer lens was used to meet sufficient performance values for 4x4 radiator antenna compared to state-of-art antennas at 15 GHz band; linear array antenna performed 12.5 dBi gain [11], grid array antenna [12] gain of 12.7 dBi and efficiency of 66%. Additionally, 15 GHz operated antenna with directivity of 15 dBi was mentioned in [13].…”

Software Defined Antenna Testing

“…The relative permeability, Er of substrates varies in the range from 1 to 10 [19]. We consider dielectric constant and dielectric loss tangent of the materials used to manufacture the antenna.…”

A broadband compact micro strip grid array antenna backed by an AMC reflector

“…4 Hence MGAA has been widely used in microwave and millimeter-wave applications in recent years. [5][6][7][8][9][10][11][12] In modern 5G wireless communication systems, antennas with high gain and wide frequency bands are greatly desired. But the traditional MGAA suffers from narrow bandwidth, which is also the major drawback of the micro strip array antenna.…”

“…This not only makes its design and fabrication easier but also avoids the radiation loss of the feeding network, resulting in a lower back lobe and enough cross‐polarization control of the pattern 4 . Hence MGAA has been widely used in microwave and millimeter‐wave applications in recent years 5–12 …”
