An antenna system of a vehicle includes a glass antenna installed on a surface of a glass of the vehicle, configured to receive a first broadcast signal and a second broadcast signal; and a broadcasting receiver configured to receive the first broadcast signal and the second broadcast signal, and to cancel and remove a harmonic components of the first broadcast signal from the second broadcast signal. The antenna system can ensure a free space of a loop antenna by implementing an integrated glass antenna, and realize installing an additional antenna module in the free space of the loop antenna.

An electronic control device may be configured to be integrated, or coupled, with a bicycle to control bicycle components. The electronic control device may wirelessly control bicycle components to trigger an action when actuated. The electronic control device may be dimensioned to have a mating surface contoured to matingly engage with a mounting surface of a bicycle, such as on a handlebar. The electronic control device may also be dimensioned to have a compact and/or concealed appearance aided by a low profile relative to the bicycle mounting surface selected for the control device.

In an antenna, the outer conductor is formed of a first linear conductor, the first linear conductor having a length corresponding to one wavelength of a right-handed circularly polarized wave and circularly extended from a first feed point to a second feed point. The inner conductor is disposed inside the outer conductor and formed of a second linear conductor, the second linear conductor being different from the first linear conductor and having a length determined based on one wavelength of a left-handed circularly polarized wave. The inner conductor has a starting point of the second linear conductor connected to the first feed point and has an end point of the second linear conductor kept free from connection at a location inside the outer conductor, and causes current to flow in a direction opposite to the current flow in the outer conductor.
