Abstract

An end fire antenna architecture based on transmission line (TML) theory is suggested. N element end fire antenna array could be constructed with N-1 elements of full wave dipole antennas and one half wave dipole antenna without additional impedance matching network. The N dipole antennas are placed with each other with a distance of quarter wave length, while the one half wave dipole antenna is at the outer most of the array, the farthest from the feeding point of the antenna array. And three 24 GHz dipole end-fire antenna arrays with gains of 7.1, 8.4 and 9.4 dB respectively are presented to explain and verify this end fire antenna architecture based on transmission line theory. Simulation and measurement results of the three end-fire antennas are given and compared. This 24 GHz end-fire antenna architecture could be utilized in 24 GHz planar end-fire antenna arrays to increase the effective isotropic radiated power (EIRP) of the transmitter.
