Abstract:
Multiband antennas are disclosed that incorporate a high frequency antenna element connected to a low frequency antenna element by a choking circuit. The choking circuit couples the high frequency antenna element to the low frequency antenna at a low frequency band and decouples the high frequency antenna element at a high frequency band. The connection created by the choking circuit can be a direct connection or can be an indirect connection via coupling elements that are capactively coupled to the high frequency antenna element and/or the low frequency element to increase the bandwidth of the multiband antenna. One embodiment includes a high frequency antenna element including a feed, and a low frequency antenna element connected to the high frequency antenna element via a choking circuit.
