The world's leading interconnection solution provider Molex announced the launch of a built-in mobile TV (TV) standard antenna product that complies with China's MulTImedia Mobile BroadcasTIng (CMMB) AV coding standard. This low-cost passive plug-and-play Mobile TV standard antennas can be integrated into any CMMB mobile device. Welson Tan, Molex Research and Development Manager, explained: "The previous built-in antenna design for highly compact CMMB mobile devices has been constrained by narrow antenna bandwidth and poor radiation efficiency. Off-the-shelf CMMB chips are not necessarily manufactured for mobile products Manufacturers provide access to control signals, and custom-designed CMMB chip implementations are expensive. Given the industry ’s need for highly compact and thin mobile products, manufacturers cannot use retractable whip antennas that have durability issues. Our mobile TV standard Antennas overcome numerous engineering design challenges, provide significant cost and time-to-market advantages, and are able to meet the needs of fashion-conscious consumers.

The new Molex built-in mobile TV standard antenna supports the receiving function of the 470-800MHz UHF frequency band, and the TV function based on the CMMB can be realized without active circuits or frequency tuning. This mobile TV standard antenna is manufactured using Laser Direct Structuring (LDS) technology, has a simple 50-ohm interface, and measures 50.0 x 5.0 x 6.0mm (1.97 x 0.20 x 0.24 inches).
A significant feature of this antenna is to hollow-out the antenna plastic material to reduce radiation loss. The antenna has a radome slot to help improve radiation efficiency, and longitudinal support bars are added to reduce warpage during molding. The hook on the side of the antenna buckles into a set of matching holes on the inner end of the product cover. This antenna is suitable for CMMB-enabled smartphones, tablets, laptops, netbooks, GPS devices, or other handheld devices.
Molex mobile TV standard antennas only need a simple matching network and the shortest PCB edge distance from the ground to optimize radio frequency (RF) performance. The compact antenna design can minimize the PCB footprint, while reducing the BOM cost and design cycle, which helps speed up time to market in the highly competitive consumer product field. This antenna supports industry guidelines for environmental protection and is RoHS compliant and halogen-free.
Molex standard and custom antenna components are based on various manufacturing and RF technologies, providing high performance and easy integration for demanding wireless applications covering industrial, consumer, medical and automotive markets.
