1. A dual band antenna circuit, comprising:
- a single antenna having an associated bandwidth spanning at least a first transmission signal bandwidth and a second transmission signal bandwidth;
a first receiver circuit configured to receive a first transmission signal characterized by the first transmission signal bandwidth;
a second receiver circuit configured to receive a second transmission signal characterized by the second transmission signal bandwidth; and
a switch configured to selectively couple one of the first receiver circuit or the second receiver circuit to the single antenna.

Abstract
A single, dual band antenna (101) is configured to receive multiple signals. The single, dual band antenna (101) is selectively coupled to either a first signal receiver (105) or a second receiver (107). In one embodiment, the first signal receiver (105) is configured to receive a time-slotted, multicast signal. Such a signal delivers data in short bursts at specified times. Between bursts, a switch (109) couples the second signal receiver (105) to the single, dual band antenna (101) to acquire the second signal. In one embodiment, the first signal receiver (105) is a DVB—H receiver and the second signal receiver (107) is a GPS or AGPS receiver.
