NAB Fastroad Investigates Improvements in Embedded Antennas
Washington - Jan 2, 2011 - NAB Fastroad released two reports on the development of improved VHF and UHF frequency band antennas to support reception of broadcast radio and mobile DTV signals in handheld devices. These Fastroad-funded projects were undertaken to help accelerate the proliferation of radio and mobile DTV receivers in cell phones, which can benefit greatly from the use of embedded antennas.
The reports present the results of separate antenna development efforts conducted by Ethertronics, an antenna systems company based in San Diego, CA, and The Technology Partnership (TTP), a technology development company based in the UK. Each company has developed new antenna methods to operate over low- and high-VHF and UHF TV band frequencies as well as the VHF frequencies which comprise the FM radio band. This broad frequency range requirement, combined with the small size and power constraints of cell phones, presented a significant challenge for design and implementation of small antenna systems.
New, embedded antenna designs, such as those developed under these Fastroad projects, offer a more attractive antenna solution to handheld device manufacturers than the headset cords or fragile, telescoping monopoles currently in use. The NAB and the antenna development partners encourage the use of these new designs by cellular handset and other portable device manufacturers for new radio and ATSC mobile DTV receiver products.
