Abstract
In order to subsitute for the normal mode helical wire antenna, bent monopole antenna combined with a helical structure is proposed as a kind of printed antenna. The antenna which can be operated at 418MHz has been simulated and designed by use of a commercial EM simulator Microwave Studio(MWS). It has been observed that the proposed antenna has good agreements between simulated results and measured results such as the return loss and the radiation pattern. The proposed antenna has been applied practically to the wireless remote controller operationg at 418MHz. It has been observed that the use of the proposed antenna result in similar antenna performance from view point of radiation power when compared with the use of the previous normal mode helical antenna.
