Compact Loaded PIFA for Multifrequency Applications
TLDR
In this article, a new multifrequency microstrip patch antenna is presented, which can be considered a PIFA since it has a metallic wall on one of its sides, and different radiation patterns for each band can be achieved if desired.Abstract:
A new multifrequency microstrip patch antenna is presented. The antenna can be considered a PIFA since it has a metallic wall on one of its sides. The different bands of operation are independent of each other, and different radiation patterns for each band can be achieved if desired. In addition, a circuital model is introduced to explain the operation of the antenna. This model presents some similarities with composite right left handed models presented in the literature. Some prototypes have been manufactured and measurements of return losses, efficiencies and radiation patterns, have been performed for a thorough characterization of the antenna as well as to validate the simulation results.read more
