Universal Wireless Connectivity


antennas are custom made and expensive, however a quad-band GSM standard antenna met the requirement. The small size, ease of use, and low-cost were key differentiators against customised antennas. Personal and professional navigation devices also require small form factors and cost effective solutions. A manufacturer of marine navigation devices was searching for embedded GPS antennas. Market-ready solutions were either too large or required significant customer design. A standard off-the-shelf GPS puck antenna exceeded all specifications for this application.


Standard antennas are not only designed for a variety of applications,


but are also intended to accommodate numerous sets of frequency bands for operation on any network - in both regional and global markets.

Growth in global cellular coverage requires that handset and other cellular devices comply with multiple standards. Design simplification has led standard antenna manufacturers to develop multi-band antennas supporting single, dual, tri, quad, and even penta band applications. This allows virtually any wireless product to operate at different frequencies without the need of multiple antennas.


Standard antennas leverage repeatable manufacturing process such as plastic injection molding, metal stamping, electroless plating and standard PCB manufacturing. These tried and tested processes maximise product reliability while minimising overall system costs. Standard design techniques such as integrated ground planes and minimal or no matching components produce small and lightweight products. Universal wireless connectivity continually affects daily life. As shown, a number of applications embed standard antennas to drive this connectivity. Proper antenna selection, while not trivial, is simplified using standard antennas. Avnet Abacus and its supplier partners have the tools and product selection to enable wireless connectivity in all products.
