Cellular /WiFi multi-band embedded flexible PCB antenna
It is equivalent to pulling out the antenna line on the PCB board and using other external metals to do the antenna. It is usually used in medium and low end mobile phones with complex frequency band and smart hardware products.
Advantages: suitable for almost all small electronic products, can do more than ten frequency band of complex antennas, good performance, low cost.

At the Green Lighting (China-ASEAN) International Conference held here, China gradually phased out incandescent lamps and accelerated the promotion of energy-saving lamps project office and China Energy Conservation Association Energy Conservation Service Industry Committee, and jointly issued a “Farewell to Incandescent Light Bulbs and Light Smart Cities†initiative. The city is called upon to speed up the process of eliminating incandescent lamps with practical actions. The meeting released the list of the first pilot cities.
This is a concrete measure for China to promote the roadmap for the elimination of incandescent lamps. In response to global climate change, since 2007, more than a dozen countries and regions such as Australia, the United Kingdom, and the European Union have successively released roadmaps for eliminating incandescent lamps. In order to actively respond to the trend of the international community to eliminate incandescent lamps, and further promote China's green lighting project, in 2011 China issued the "Announcement on the gradual ban on the import and sale of ordinary lighting incandescent lamps", decided to start from October 1, 2012, according to the power size Import and sale of general lighting incandescent lamps are phased out in stages. Among them, the third stage, since October 1, 2014, prohibits the import and sale of ordinary lighting incandescent lamps of 60 watts or more.
Lu Wenbin, deputy director of the Department of Resource Conservation and Environmental Protection of the National Development and Reform Commission, said that through the implementation of green lighting projects, China has achieved remarkable results in energy conservation and emission reduction, forming an annual energy saving of 32 billion kWh and reducing the capacity of carbon dioxide emissions by 24 million tons. Significantly optimized, the proportion of energy-saving lamps and incandescent lamps increased from 1:1 in 2009 to 1.28:1 in 2013; the market share of high-efficiency lighting products continued to increase, from 67% in 2009 to 85% in 2013.
Jia Fusheng, director of the National Energy Conservation Center, said that China is a major producer and consumer of global lighting products. In 2013, the output of incandescent lamps was 3.89 billion, accounting for about one-third of the world's total output; the output of energy-saving lamps was 4.16 billion, accounting for about 80% of the global production. If all the incandescent lamps in use are replaced with energy-saving lamps, the annual energy saving will be 48 billion kWh, equivalent to 48 million tons of carbon dioxide emission reduction, and the potential for energy saving and emission reduction is huge.
Attached to the list of the first pilot cities of “Bid farewell to incandescent bulbs and light up smart citiesâ€:
Wuhan City, Hubei Province, Zhengzhou City, Henan Province, Nanjing City, Jiangsu Province, Jinan City, Shandong Province, Lanzhou City, Gansu Province, Linyi City, Shanxi Province, Shizuishan City, Ningxia Hui Autonomous Region, Huludao City, Liaoning Province, Hebi City, Henan Province, Tongliao City, Inner Mongolia Autonomous Region City, Zhongwei City, Ningxia Hui Autonomous Region, Jiyuan City, Henan Province, Zunyi City, Guizhou Province, Tongren City, Guizhou Province, Zhangzhou City, Anhui Province, Changshu City, Jiangsu Province, Xiangtan City, Hunan Province, Tongxiang City, Zhejiang Province, Haiyang City, Shandong Province, Jiangsu Province Fengxian County, Xinping County, Yunnan Province. 
Disadvantages: need to be debugged separately for each product.
21 counties and cities across the country recently signed a proposal to bid farewell to the incandescent light bulbs and light the smart city. The contract energy management will be adopted to accelerate the implementation of green lighting renovation. All incandescent lamps will be eliminated within the city by 2017. Efficient lighting products are used in all large public buildings.
PCB antenna is widely used in Bluetooth module, WiFi module, ZigBee module and other single-band module circuit boards.
Advantages: the cost is very low, a debugging without debugging again.
Disadvantages: suitable for single band, such as Bluetooth, WiFi. Different batches of PCB antenna performance will have certain deviation.
