Pattern diversify patch antenna for sub-6 GHz 5G communication applications
A dual-port single-layer pattern diversified microstrip patch antenna for sub-6 GHz 5G communication applications is proposed. The design consists of a notch-loaded annular ring with a separately excited slot-loaded circular patch within its aperture. The broadside radiation is achieved by exciting the dominant TM<sub>11</sub> mode of the circular patch while TM<sub>31</sub> mode of the annular ring is excited to obtain conical radiation patterns. The two modes of radiating elements operate at a frequency of 3.5 GHz which lies in the sub-6 GHz 5G frequency band. The measured results of the fabricated prototype are in good agreement with the simulated ones. The gain of the broadside beam is 7.2 dBi while the gain for the conical one is 4.6 dBi. The isolation between the two ports remains below - 28 dB.
