Yes that is possible. You don't say much about the history of your device and that is the most important thing to give when you ask people who don't have access to your phone for repair advice.

The related IC's could go bad but that is pretty rare. When things fail, it is usually related to drops, water damage, excess heat, bending/flexing etc.

So if you recently dropped your phone or it happens often enough, then the antenna flexes, may be partially or completely disconnected. Open you phone, following this guide[guide|30696], and check all the connections. Be very careful as the flexes are delicate and keep track of which screw goes where.
