Abstract :
In this paper, a measure of image-rejecting capability of an antenna for wireless communication devices is introduced and a loaded dipole antenna is designed to reject the image component for Korean personal communication system handset applications. The image-reject ratio for a receiving antenna is defined as the received power ratio of the image-frequency component to the desired frequency signal component for the same incident radio power density. An example image-reject dipole antenna shows that dramatic improvement in image-rejection capability can be realized without seriously compromising signal reception capability in the desired frequency band.
