Possible, but unlikely. When was the last time you saw a cellphone with an external antenna?
Last cellphone I saw with an external antenna - iPhone 5, where the case is the antenna... same goes for iPhone 4/4S
In any event, even if you see a pointy antenna, doesn't mean it's real - Motorola, years back, actually shipped a very popular phone that had a pull out thing that folks that was the antenna, but actually wasn't - the real antenna was inside the phone - if I recall it was one of the old Analog Microtacs for a big east coast Cellular carrier where the certification/acceptance team insisted on having an external antenna...
Interesting history/trivia moment - this goes back a few years...
Internal antenna's were driven by two factors - design, folks wanted pretty phones, and FCC's implementation of SAR Limits. How FCC tested this - they used a head and torso simulator (HATS fixture), and with the phone in the position where people would have it next to their head, made much more sense to put the antenna at the bottom of the phone, away from the ear, which was positioned right against the head.
Now a phone with an external antenna pointed down would look pretty awkward, so that's what drove the antenna inside the phone. Now imagine what a phone would look like with multiple antenna's these days - two for Rx diversity (you can use one or both for Tx diversity), one for BT/WiFi, one for GPS, and the phone would look like a porcupine in rapid manner - lol...
The first internal antenna's were pretty horrible - typically -0.5 to -1.5 dB gain, as the RF front ends (PA and LNA for Tx/Rx) were designed more for external whips and coil stubbys - we'd have to juice the hell out of the PA's to get decent Tx performance, and Rx was always a challenge - this is 800/900 and 1800/1900 MHz bands for cellular/PCS.
But antenna design has improved significantly over the past few years - better computer programs, lessons learned, and the more recent RF front ends have this all accounted for.
The takeaway here is that much of what was learned in the mobile space has trickled down in the WiFi space, and most of the internal antenna designs you see these days are pretty efficient, on par with external Dipole's that you see on some gear - it's mostly cosmetic, as some folks do equate pointy things as being somehow better
who knows, those external antenna looking things, they might not even be real
