| How to Avoid a Costly PTCRB Test Failure and Build Smaller Cellular IoT Products with Inpai antenna | 2025-05-14 |
PTCRB certification is a critical step for any cellular device destined for the U.S. and Canadian markets. Failing these tests - particularly those required by AT&T, Verizon and T-Mobile can delay product launches and drive up costs with repeat certification attempts. One of the most common causes of failure can come from the antenna integration. That’s where Inpai (P/N SR4L099), Antenova’s newly developed SMD antenna, changes the game - meeting PTCRB requirements with ease and enabling engineers to create smaller, more compact cellular devices without compromise. More than just another 4G/LTE antenna, Inpai is a purpose-built solution that delivers sufficient performance to pass PTCRB certification even on reduced 100mm/110mm length ground planes giving a 20% size reduction compared to typically 120mm or more for standard cellular antennas. |
