The 'antenna ratio' of an inter-connect is used to predict if the antenna effect will occur. 'Antenna ratio' is defined as the ratio between the physical area of the conductors making up the antenna to the total gate oxide area to which the antenna is electrically connected. When your transmitter puts a current (Radio Frequency (RF) energy) into an antenna, your antenna responds by producing a magnetic field surrounding the antenna (this is the signal). When this magnetic wave strikes another antenna (the receiving station antenna), it induces a current on the receiving antenna surface (that current is then converted by the receiving
