  • Patent number: 12249774
    Abstract: A wireless microphone system utilizes an antenna structure that supports dual frequency bands. With some embodiments, the wireless microphone system comprises a first apparatus (for example, a wireless transmitter) and an attached second apparatus (for example, an attached microphone), where the chassis of the first apparatus and the housing of the second apparatus support the antenna structure through an electrical connector (for example, through an outer shell of a Cannon (XLR) connector) between the two apparatuses. The chassis and the housing may support first and second halves of a dipole antenna, respectively. The first apparatus supports first and second electrical circuits that are operational within a first and second frequency band, respectively, and that connect to first and second input ports of a combining circuit (for example, a diplexer filter). The output port of the combining circuit connects to the housing through the electrical connector.
