Web18 de out. de 2024 · Antenna gain is symmetric for transmitting and receiving. If an antenna radiates more power in a particular direction, then this antenna will also be better at receiving electromagnetic waves in that particular direction. Beam/Radiation Patterns. One can represent the gain of an antenna in all directions through a plot of its radiation pattern. Web12 de abr. de 2024 · A dual-wire antenna above the ground plane radiates a circularly polarised (CP) wave [1-3]. The antenna is characterised by a two-element array configuration with a single-balanced feed.
