Surface-Mount Pifa Using Ball Grid Array Packaging for 5g Mmwave

Abstract

In this letter, a surface-mount planar inverted-F antenna (PIFA) is proposed for the 5G mmWave system using ball grid array packaging (BGA). To meet the requirement of cost-effectiveness, the proposed antenna element is designed on a single FR4 layer to achieve low cost. To achieve a compact size, the BGA packaging is used on the proposed antenna element. Finally, the size of the antenna prototype is only 4.5 mm × 4.5 mm × 1.3 mm. Besides, the surface-mount feature allows the proposed antenna to be integrated with other devices in the same system package. The simulation and measurement results are discussed in detail. The measurement results show that the impedance bandwidth of −10 dB is 15.3% (24.7-29.6 GHz), and the peak gain is 5.85 dBi at 28 GHz. The proposed PIFA can be used in the 5G NR bands N257 (26.5-29.5 GHz), .

Analysis of Super-Solar Integrated Patch Antenna for Sub-6 GHz and Beyond 6 GHz Millimeter Wave 5G Applications

“…To suit costeffective needs, an FR4 printed circuit board has recently been used as the substrate. Many low-cost mm-wave antennas [26][27][28][29][30][31][32] have been reported, including planar inverted-F antennas (PIFA) [28], U-shaped slot patch antennas [29], ball grid array (BGA) packaged ring slot antennas [30], BGA surface-mount bowtie antenna [31], and double-curved metal in multilayer printed circuit boards [32].…”
