The 18th China International Hi-Tech Fair was held in Shenzhen from November 16th to 21st, 2016. The theme of this year's Hi-Tech Fair is “Innovation Driven, Quality Leadingâ€, focusing on energy conservation, environmental protection, new technologies, biology, Advanced technologies and products in the energy and other industries have highlighted major breakthroughs in the frontier areas and achievements in innovation and entrepreneurship, but there has been an episode at this high-tech fair.
A robot named Xiaopeng suddenly malfunctioned and smashed the booth glass without instructions. Eventually, some of the booths were destroyed. What is more serious is that the robot also injured the passers-by and exposed the pictures from the Internet. We saw that the injured had been taken away by the stretcher.
The chubby robot was originally developed for children aged 4-12, mainly for educational purposes, but it seems that this robot has great flaws, and parents will not be assured of giving their "heart" to it.
An Internal PCB (Printed Circuit Board) Antenna is a type of antenna that is integrated directly onto the surface or embedded within the layers of a printed circuit board. This design approach offers several advantages over traditional external antennas, making it a popular choice for modern electronic devices such as smartphones, tablets, laptops, and wearable technology. Internal PCB antennas are a versatile and efficient solution for modern electronic devices. Their space-saving design, durability, and performance characteristics make them an attractive alternative to traditional external antennas.
Key Features and Advantages of Internal PCB Antennas:
Space Efficiency: Internal PCB antennas eliminate the need for a separate antenna housing, freeing up valuable space within the device. This is particularly important in compact devices where every millimeter counts.
Aesthetics: By hiding the antenna within the PCB, manufacturers can create sleek and seamless designs that are visually appealing. This enhances the overall user experience and makes the device more attractive to consumers.
Durability: External antennas are prone to damage from impact or environmental factors. Internal PCB antennas, on the other hand, are protected by the device's housing, reducing the risk of damage and increasing the device's overall durability.
Performance: Modern internal PCB antenna designs are highly optimized for specific frequency bands and can achieve excellent performance characteristics, including high gain, low noise, and wide bandwidth.
Integration Flexibility: Internal PCB antennas can be easily integrated into the device's PCB layout, allowing manufacturers to customize the antenna's position, orientation, and size to suit their specific needs. This flexibility also facilitates the integration of multiple antennas for MIMO (Multiple Input Multiple Output) systems, enhancing data throughput and reliability.
Cost-Effectiveness: While the initial design and engineering costs of internal PCB antennas may be higher than those of external antennas, the overall cost savings achieved through space efficiency, reduced material usage, and simplified manufacturing processes often make them more cost-effective in the long run.
Types of Internal PCB Antennas:
Planar Inverted-F Antenna (PIFA): A popular choice for mobile devices, PIFA antennas are compact and offer good performance across a wide range of frequencies.
Chip Antennas: Small, low-profile antennas that are designed to be mounted directly onto the PCB. They are ideal for space-constrained applications.
Monopole Antennas: Simple, single-element antennas that can be embedded within the PCB or mounted on its surface.
Meandered Antennas: Antennas with a complex, serpentine-like shape that allows them to fit within a small area while maintaining good performance.
