Abstract
An antenna assembly for a wireless communications device has an antenna, a filter circuit, and a connector constructed to engage a wireless communications device. A filter circuit includes a band-pass filter and a first notch filter disposed in serial electrical communication with the band-pass filter, the band-pass filter operable to permit the passage of oscillatory electrical signals in a first frequency range, the first notch filter operable to impede the passage of oscillatory electrical signals in a second frequency range, the second frequency range residing within the first frequency range.

An antenna assembly for a wireless communications device, the antenna assembly comprising:
- an antenna for wirelessly receiving data;
- a filter circuit in electrical communication with the antenna;
- a connector in electrical communication with the filter circuit, the connector constructed to dispose a wireless communications device into electrical communication with the filter circuit by engaging the wireless communications device;
- whereby when the connector is in engagement with the wireless communications device the received data is provided to the wireless communications device by way of the filter circuit and the connector;
- and
- wherein the filter circuit comprises a band-pass filter and a first notch filter disposed in serial electrical communication with the band-pass filter, the band-pass filter operable to permit the passage of oscillatory electrical signals between the antenna and the connector in a first frequency range, the first notch filter operable to impede the passage of oscillatory electrical signals between the antenna and the connector in a second frequency range, the second frequency range residing within the first frequency range.
