Abstract—In this paper, ultra-wideband and miniaturization, technique for the microstrip monopole patch antenna (MMPA) in wireless applications is presented. Ultra-wideband was achieved by using printed modified ground plane on a dielectric substrate with 50Ω microstrip feed line. This technique allows the bandwidth of the MMPA to be ultra-wideband with satisfactory radiation properties and red...

1. Introduction With the rapid growth of various wireless services and applications calling for high data rate transmission there is a demand for developing robust wideband wireless technology. In order to counter count adverse phenomena such as multi-path signal propagation and interference, which become more pronounced in wideband systems, smart antennas can be employed as a remedy.
