Problems solved by technology

Unfortunately, the components required to achieve FM phase difference using at least two external FM antennas are expensive, inhibiting vehicle manufacturers from implementing FM phase difference on high-volume and / or low-price vehicles
Furthermore, for vehicle manufacturers, FM phase differences can increase assembly costs and be a source of reliability issues

Embodiment Construction

[0012] refer to figure 1 , which illustrates an exemplary environment or system 20 in which the principles of the present disclosure may be implemented. System 20 has FM phase difference capability and is adapted to provide improved FM reception and performance over systems without FM phase difference capability. Additionally, system 20 is adapted to provide a less expensive option to achieve FM phase difference capability. In the exemplary embodiment shown, the system is a vehicle 20 . The illustrated vehicle 20 is an exemplary vehicle only, and is not intended to be limiting. Rather, any type of vehicle may incorporate the principles of the present disclosure.

[0013] The exemplary vehicle 20 includes a cabin 24 in which passengers ride during operation of the vehicle 20, an external antenna 28 located outside the cabin 24, a radio unit 32 located inside the cabin 24, and a radio unit electrically coupled between the external antenna 28 and the radio unit 32. Between th...

Abstract

The present invention provides systems, apparatus and methods for providing FM phase difference capability. In some aspects, a vehicle system includes: a first FM antenna located on the exterior of the vehicle and adapted to receive a first FM signal; a radio unit located on the interior of the vehicle and including a display and at least one user control; a cable , which is electrically coupled to the first FM antenna and the radio unit to transmit the first FM signal to the radio unit; and a second FM antenna, located inside the vehicle and adapted to receive the transmitted A second FM signal to the radio unit. In another aspect, a radio unit located inside the vehicle may include a printed wiring board, and a second FM antenna may be located on the printed wiring board inside the vehicle and adapted to receive a second FM signal.

Description

technical field [0001] In general, the present disclosure relates to FM phase differences for vehicle radios, and more particularly, to apparatus, systems, and methods for providing FM phase differences for vehicle radios utilizing a single external antenna. Background technique [0002] Vehicles attempting to have FM phase difference capability require at least two FM antennas located outside the cabin to bring the FM signal to the vehicle radio unit located inside the cabin. Exemplary external locations for FM antennas include the roof of the vehicle, rear view mirrors, and the like. Other vehicles without FM phase difference capability include only a single FM antenna throughout the vehicle, and this single FM antenna is located outside the cabin to carry the FM signal into the vehicle radio. Vehicles with FM phase difference capability may have significant improvements in FM reception and performance compared to vehicles without FM phase difference capability. This imp...
