Nowadays wireless devices are commonly used in modern life. Own brand companies or electronic wireless devices design suppliers are specialized in system integration, circuits design and or mechanical design. When it comes to antenna, which is a must-have part for wireless units, most of the engineers deemed antenna as a plug-and-play component and is easy to matching. In some cases, when the circuits design is proper or the electromagnetic environment is acceptable, applying so-call standard external antennas or embedded chip antennas is applicable.
While the size of the wireless devices become smaller and miniaturized, furthermore, more and more wireless technologies like cellular LTE, Wi-Fi/Bluetooth, unlicensed ISM bands, and GPS/GNSS are included in a single unit, however, the challenge for antenna placement and implication becomes a serious topic to deal with. Engineers always need to review the antenna design to see if there is any way to decrease the size of the antenna without compromising its performance. For some radio failure cases, antennas are required to be redesigned to meet the public standards of the authorities or telecom service vendors. Electromagnetic interferences are one of the major issues which lead to system failure: measuring the radio-frequency characteristics of the main board and the antenna performance figures shall be helpful for identifying the root causes of the problem. In the above-mentioned cases, design engineers of the system integrators demand for antenna design services from the antenna design companies as developing qualified anechoic chambers or hiring a team of antenna design experts is costly and not efficiently.
To save monetary or human resources, outsourcing for antenna design services shall be a smart and cost-effective way for system developers to apply. Engineers are able to spend more time on improving the overall design and competitiveness of the products to develop, leaving the antenna measurement, evaluation, and design to antenna design companies.
