The Dual Band 5G Antenna

THE DUAL BAND 5G ANTENNA Introduction  5G uses low, mid and high frequency bands for high data rates  Mid band of 1-6 GHz chosen for good propagation compared to mmWave  Compact microstrip antennas suitable for 5G mobile devices Antenna Design  Compact square slot patch antenna with partial ground plane  Meander line inside slot for dual band response  Bar along meander line introduces notch in undesired band Results  Dual band from 3.34-4.25 GHz and 4.65-7.07 GHz  Covers n77, n78, n79 mid bands allocated for 5G  Stable gain of 2-3 dBi across bands  High radiation efficiency >80% Analysis  Square patch provides base resonance  Meander line generates additional resonance  Bar filters out unwanted frequencies  Compact size due to slot, partial ground, meander line Conclusion  Proposed antenna covers all key 5G mid bands  Compact size and low profile suitable for mobile devices  Stable gain and high efficiency achieved  Meander line technique enables miniaturization Key Highlights  Dual band resonance realized in compact planar geometry  Meander line and slotting techniques used for size reduction

 Notch introduction filters unwanted bands from wide response  Covers all important 5G frequency allocations in sub-6 GHz
