AB In this communication, a novel dual-polarized highly foldedself-grounded Bowtie antenna that is excited through I-shaped slotsis proposed for applications in sub-6 GHz 5G multiple-input-multipleoutput(MIMO) antenna systems. The antenna consists of two pairs offolded radiation petals whose base is embedded in a double layer of FR-4substrate with a common ground-plane which is sandwiched between thetwo substrate layers. The ground-plane is defected with two I-shaped slotslocated under the radiation elements. Each pair of radiation elements areexcited through a microstrip line on the top layer with RF signal that is180º out of phase with respect to each other. The RF signal is coupledto the pair of feedlines on the top layer through the I-shaped slots fromthe two microstrip feedlines on the underside of the second substrate.The proposed feed mechanism gets rid of the otherwise bulky balun.The Bowtie antenna is a compact solution with dimensions of 32 × 32 ×33.8 mm3.Measured results have verified that the antenna operates over afrequency range of 3.1–5 GHz and exhibits an average gain and antennaefficiency in the vertical and horizontal polarizations of 7.5 dBi and82.6%, respectively.
