If you remember the early days of mobile phones, you’ll clearly recall the big, bulky antennas that formed part of their signature look. It’d be unthinkable for a new iPhone or Pixel to have an external antenna these days, and unnecessary too. So when exactly were they phased out?
Why Did Phones Used to Have Big Antennas?
The earliest cell phones had very prominent, and often extendable, external antennas. They were a consequence of all sorts of limitations in the technology of the time.
The phones ran on first-generation (1G) networks. These were analog and were used exclusively for voice calls. They ran at lower frequencies, often around 800-900MHz, which means that they had longer wavelengths and so needed larger antennas.
On top of that, antenna design was more primitive, and the infrastructure was less well-developed. Network coverage was far patchier, especially away from the most built-up areas. The result was often poor call quality and lots of dropped calls. Larger antennas were an attempt to get around this.
Also, there was no real consumer demand for anything smaller. Mobile phones were new, so nobody really knew or expected anything different. In fact, the first generation devices were predominantly car phones rather than personal devices.
When Did Antennas Become Internal?
The move to second-generation networks in the 90s marked the beginning of the end for the external antenna.
The phone that is most widely credited as being the first without a large external antenna is the little-known Toshiba TCP-6000, released as the Hagenuk GlobalHandy, in 1996. It still needed an antenna, of course, as all phones do, but it was fully integrated inside the casing.
Nokia got in on the act in 1998 with the 8810, but made the first real breakthrough into the mainstream with the 3210 in 1999. That was followed a year later by the iconic and still fondly remembered Nokia 3310.
The change came about because 2G was digital, which allowed for cleaner signals, higher capacity, and smaller hardware. It ran at higher frequencies, meaning shorter wavelengths and smaller antennas. Throughout the late 1990s and early 2000s, antenna design became more advanced, and improved coverage required less power to retain a signal.
The move to digital also enabled the introduction of text messaging over SMS, and even basic (and very slow) data connections, bringing about the birth of the mobile web. Phones increasingly became something that people would want to carry with them all the time, so smaller became a much more important design priority.
But it took a while longer for the US to fully embrace the internal antenna. While much of the world had adopted the GSM standard for 2G, America had a combination of GSM and the CDMA network supported by Verizon. That complicated matters, as did the large rural areas where network coverage remained patchier. With different frequencies and less uniform coverage, manufacturers would often stick to external antennas to ensure reliability.
Antennas got smaller and stubbier, but it took a while for them to disappear entirely. By the time of the launch of devices like the Moto Razr V3 in 2004, along with the growing popularity of BlackBerry, internal antennas were common.
As networks developed through 3G, 4G, and 5G, frequencies climbed higher, and data became more important than voice, antenna size was able to shrink even further. When the iPhone brought in the smartphone era in 2007, the external antenna was a thing of the past.
Where Is the Antenna Now?
Every phone has multiple antennas, not just for a cellular connection, but for Wi-Fi, Bluetooth, GPS, and more. Antennas are now typically flat and positioned around the edges of the phone’s casing. Modern phones have multiple antennas for different bands and technologies, and you can see them if you look closely.
The infamous “antenna-gate” controversy that hit the iPhone 4 in 2010 was an early fail, and showed how tricky internal antenna designs can be. Then, the metal casing functioned as the antenna, but if you “held it wrong,” it could cause it to lose signal. Even years later, that experience still puts some people off buying a new iPhone on release day.
Most phones now have thin strips of plastic around the edges called “antenna lines.” These enable radio signals to pass through materials like metal that would otherwise block them. You can see it very clearly on the iPhone 17, which has the antenna lines integrated neatly into the camera bump. On the iPhone 17 Pro and Pro Max in the US, there’s an additional large antenna window on the top edge for 5G mmWave connectivity that’s presumed to be glass.
Sleek Lines
We’ve just about passed the point in cellphone history where internal antennas have been around for longer than external ones, with a modern phone’s sleek design hiding what’s inside. And no one is complaining. The only place you’re likely to see an external antenna on a phone today is in the hands of a yuppie in an ’80s movie.
