Abstract :
A novel integrated antenna is proposed for LINC (linear amplification using non-linear components) transmitters. In this antenna, the power combiner involved in the conventional LINC is removed, and the power combination is realized within a microstrip antenna. By using a dual-fed H-shaped microstrip patch, the antenna can suppress higher harmonics and occupy a smaller size compared to a rectangular patch. An example antenna is designed at 1.8 GHz. The simulated results based on the moment method are presented, which validate the concept.
