Modified L-type eloran transmitting antenna for co-location with an AM antenna

Hanni Koo, Sangwook Nam

Abstract

The modified L-type eLoran (enhanced Long Range Navigation) transmitting antenna is proposed for co-location with an AM transmitting antenna in a limited area. To compensate for the loading effect, the inverted L-type antenna is modified by adding the umbrella-type loading. The AM antenna is co-located with the radiator part and the loading part of the proposed antenna. The simulation results of the eLoran antenna show 1.4 kHz bandwidth and 32.5% radiation efficiency. Also, the validity of the co-location between the AM antenna and the eLoran antenna is verified through the simulation results of the radiation pattern and the antenna coupling. The proposed eLoran antenna can be used with the AM antenna in the same area.
