Abstract: A one-way gateway and a vehicle network system and method for protecting networks within a vehicle using the one-way gateway. The one-way gateway includes a communication control unit, a physical one-way communication unit, and a data transmission/reception unit. The communication control unit takes charge of communication with a device of the internal network or infortainment network of a vehicle. The physical one-way communication unit configures a communication section between the internal network and the infortainment network in a physically one-way form. The data transmission/reception unit transfers data, transmitted by the device of the internal network or infortainment network, to the physical one-way communication unit via the communication control unit, and transfers data, received via the physical one-way communication unit, to the device of the internal network or infortainment network.

Abstract: A circularly polarized Global Positioning System (GPS) antenna using parasitic lines, in which circular polarization is implemented to improve the efficiency of the reception of satellite signals by an antenna. For this, a circularly polarized GPS antenna using parasitic lines according to an embodiment includes a substrate, a radiating patch formed on a top of the substrate, a parasitic line part formed on the top of the substrate and disposed to be spaced apart from the radiating patch, thus implementing circular polarization characteristics by inducing reverse current, a ground plate formed on a bottom of the substrate, and a feeding via formed through the substrate and configured to electrically connect the ground plate to the radiating patch.

Abstract: Disclosed herein is a controlled reception pattern antenna that prevents the degradation of anti-jamming performance in a compact array antenna by increasing the antenna gain at a low elevation angle. The proposed antenna includes a radiator for receiving a satellite signal, a ground platform in which the radiator is arranged, and a radiating slot formed in the ground platform. By simply forming a radiating slot in the ground platform, antenna gain may be increased at a low elevation angle. Therefore, it is possible to maintain anti-jamming performance and to reduce the size of the array antenna.
