The more energy absorbed by the nearby antenna, the less will be transmitted for … Web(d/λ) between array elements increases with frequency. At different frequencies, the same interelement phase shift corresponds to different time delays and therefore different angles of wave propagation, so using the same phase shifts across the band causes the beam direction to vary with frequency. This effect is shown in Fig 3-3. This beam
