Abstract
A method of transmitting from a traffic alert and collision avoidance system (TCAS) directional antenna, the TCAS directional antenna including a plurality of antenna elements connected to an integrated beam forming network, according to various aspects of the present invention comprises: providing a signal to each input of the integrated beam forming network, wherein each signal is of equal phase and equal amplitude to result in transmitting omnidirectionally from the TCAS directional antenna.
