“…An 8-element phased array using open-slot PIFA antenna at mm-wave is designed for beamforming applications with an inter-element spacing of half a wavelength, reporting only simulated results [15]. In [16], a 4-element MIMO PIFA array is presented at 28 GHz. Three MIMO array models/arrangements are presented using space diversity where each element is located in a different arrangement with an inter-element spacing of half a wavelength [16].…”

This paper presents a four-element compact phased Planar Inverted-E Antenna (PIEA) array for 6 GHz beamforming applications. For compact phased arrays, the mutual coupling is a severe performance degrading factor. Therefore, three mutual coupling reduction techniques are employed, which include (i) PIEA as an array element which is a modified version of Planar Inverted-F Antenna (PIFA) by inserting another shorting plate, (ii) slots in the ground plane and (iii) two slits in each etched ground slot. With these techniques, the mutual coupling is reduced below −19 dB in the operational bandwidth from 5.7 to 6.4 GHz. The compact design with an inter-corner spacing of 0.013λ o and an inter-element spacing of 0.3λ o is achieved. The peak gain obtained by this compact phased array is 8.36 dBi. This array can scan up to a maximum scanning angle of ±70 o. A good general agreement is found between the measured and simulated results.

Planar inverted F antenna (PIFA) is mainly fit for mobile devices. PIFA is mostly designed for dual band frequencies as it is capable of covering wide range of wireless services. This in turn helps in making it acceptable for designing mobile devices. Sizes of ground plane as well as PIFA’s position with respect to ground plane actually effect the performance of PIFA. For example, placement of PIFA at corner of ground plane shows good radiation pattern. Major prerequisite of 5G is nothing but the capability to enhance data volume to every single user, while supporting majority of mobile users as well as new maneuvers. The best part is advanced antenna array technologies are able to meet such requirements. Although PIFA antenna has gained popularity in designing mobile handsets, because of light weight, lower cost as well as higher directivity, PIFA antenna Arrays have been proved to be strong foundation for future 5G Mobile Communication Systems as PIFA Arrays provide better gain than single PIFA antenna in same frequency band. Current work presents a comprehensive study on so far impact of PIFA as well as PIFA Array in providing infrastructure for future mobile innovations suitable for 5G communication.
