• VSWR, Return Loss and S11: What the Numbers Mean for an IoT Antenna — VSWR, return loss and S11 are three views of one defect — reflected power. VSWR 2.0 costs only 0.51 dB of mismatch loss, so the number that really matters is whether the antenna stays matched across the band in your enclosure, not whether it hits
• Smart Metering Antennas in 2026: The EED Deadline, Pit Installations and 10-Year Batteries — Metering is the highest-volume, longest-lived antenna application in LPWAN. The EU requires existing meters to be remotely readable by 1 January 2027, China Southern Power Grid runs over 130 million meters at 99.68% automatic reading — and the antenna is the component that decides whether a 10-year battery
• 4G LTE and 5G NR Band Frequency Table (with China allocations) — Uplink and downlink ranges for the mainstream LTE FDD/TDD bands and 5G NR FR1 bands, plus the Chinese operator allocations. Use it to check whether a wideband '4G/5G antenna' really covers the bands your modem will
• 5G RedCap and eRedCap: What Reduced-Capability 5G Means for Antenna Design — RedCap caps bandwidth at 20 MHz and drops the two-receive-branch requirement, so a RedCap device can ship with a single well-designed antenna instead of a MIMO set. It does not relax band coverage — that 20 MHz is instantaneous bandwidth, not frequency
