For decades, both the antennae and the microwave engineering have been inextricably linked. Both are highly professional and complex, and neither side's experts question the expertise of the other. Microwave engineers focus on how to through a variety of active (amplifier, oscillator, active tuner, etc.) and passive (filters, couplers, separator, etc.) device to adjust the radio waves, and antenna engineers have been studying the increasingly complex based on fractal geometry and related antenna structure innovation methods from by the manipulation of the waves. However, with the introduction of "no antenna" technology, this division may change radically. Compared with traditional antenna engineering, this technique makes antenna design more similar to filter design.
The principle of non-antenna technology is to replace the complex custom antenna design with a ready-made standardized micro-component called antenna intensifier. Antenna booster itself is the chip shape, SMT, so that they can like other electronic components (such as microprocessors, memory, amplifier, filter, or switch) as fit perfectly to the printed circuit board. It can also be combined with a traditional chip to make the design and manufacturing process of the next generation of IoT/ mobile or wireless devices simpler, faster and more efficient.
For the antennas and microwave engineers, the tiny patch antennas have been around for decades, and what makes these new antennas different? One big innovation is their ability to multiband. The traditional micro patch antenna USES a high dielectric constant ceramic material, which is good for narrowband single-frequency applications such as bluetooth and GPS. A single new antenna booster can achieve full mobile performance in broadband segments such as 698 to 2690MHz. In addition, they are made from traditional low-cost materials, such as epoxy glass substrate or plastic mold components, so that off-the-shelf components can be mass-produced at low prices.
Antenna engineers have a mantra about increasing the number of bands and reducing the size of the antenna: "change the size wavelength." Although antenna technology has been in progress, and constantly generate more complex shape to meet the demand of small space of multiband, in between 2008 and 2012, however, seems to meet the technical bottleneck, no matter how to also cannot be further narrowed the antenna size. Chu and Wheeler, put forward in the 1940 s, after all, the basic conditions: any smaller than working wavelength devices (e.g., lambda / 10 or less), its radiation condition are affected, in extreme cases even won't produce radiation. So how do these small antenna intensifiers, which are much lower than this limiting condition (often 1/30 or 1/50 of the working wavelength), reach full radiation at the moving frequency? How do they achieve full radiation at multiple mobile/wireless wavelengths?
