On several occasions transportation vehicles require several antennas mounted on the roof. Each antenna presents an object that can reflect radio transmission back into the transmitter that is operational and noise on the ground plane because of the poor material electrical properties. This chapter presents three examples of how radiation may affect ground plane noise. The first is the radio transmitting antenna with a receiving antenna nearby mounted on cold rolled steel ground plane. The second and third examples are a similar configuration with a stainless steel ground plane and a copper ground plane, respectively. The chapter reviews antenna reflection and diffraction at the edge of the ground plane. In the antenna farm application, four patch antennas are clustered in an area and sheltered by a ray dome cover. The chapter provides a guide for the electromagnetic compatibility (EMC) engineer when determining loss between patch antennas that are closely spaced.
