The main work of this thesis is about the study on the handset internal planar monopole antennas
the technologies of multi-band and broadband of the handset internal planar monopole antennas are analyzed in detail.For the current research focus and development trends
One internal planar monopole antennas are designed
simulated and measured.It’s operated at GSM/DCS/PCS/TD-SCDMA frequency band.The good conformity between simulation and measurement is achieved
which proves these antennas suitable for new generation mobile communication applications.The four-band planar monopole antenna has been used
