Antennas Aren’t Extinct

This is the reason companies like Apple and Samsung are leaving their competition in the dust: everything they come out with hit all the right notes when it comes to looks. It doesn’t hurt that they’re technologically ahead of the curve either.

Antennas Are So Last Millennium

Smartphones and gadgets have been constantly changing and adapting to balance form and function. Today, that balance seems to have been struck, which is why people are seeing phones of similar designs coming from their favorite brands. Nevertheless, these changes in appearance have fostered falsehoods in many of their features, the most famous of which is that phones no longer have antennas.

For people too young to know what an antenna even looks like, they’re the rods at the top of handheld radios. Cell phones used to have retractable ones, but it’s been decades since the last one of those models were seen, which led many to assume that antennas are part of an obsolete past.

Antenna Waves

This isn’t true, as there are antennas in phones right at this moment; they’re just hidden. Any wireless device depends on antenna technology to stay connected to the rest of the world. Wireless signals for phones are encoded on unique wavelength known as the carrier frequency. The frequency is a periodic oscillation of an electric and magnetic field; it’s the modulation of the field’s amplitude that carries the information people want to send.

Think of it this way: the wireless information is a boat on the high seas. The waves are the carrier frequency that moves the boat towards the destination. In this analogy, an antenna is a buoy that the boat crashes into in a transfer of information. The question is, why don’t modern cell phones have such antennas if they’re so essential? They do, it’s just that modern devices can communicate to each other using frequencies that smaller antennas can detect; all this in an effort to make technology more stylish.
