Designing for 5G NR: Antenna Challenges and Solutions
Unveiling the Complexity: Key Antenna Design Considerations for 5G NR The fifth generation of cellular technology, 5G New Radio (NR), promises blazing-fast speeds, ultra-low latency, and massive device connectivity. But achieving these groundbreaking capabilities requires a leap forward in antenna design. Traditional antennas struggle to keep pace with the demanding frequency ranges and intricate modulation schemes of 5G NR. Let's delve into the crucial considerations engineers face when designing antennas for this revolutionary technology. 1. Operating Frequency Bands: 5G NR operates across a vast spectrum, encompassing low-band (sub-6 GHz), mid-band (2-4 GHz), and high-band (mmWave) frequencies. Each band presents unique challenges: Sub-6 GHz: While offering long range and good penetration, these lower frequencies require larger antenna sizes to achieve optimal...
