In this thesis, FR4 substrate and IE3D software are used to design multi-band antennas, including comb shaped with rectangular arm dipole antenna which can be applied to 1.8GHz,2.4GHz,2.45GHz and 2.6GHz frequency bands, comb shaped with needle arm dipole antenna which can be applied to 1.8GHz,2.4GHz,2.45GHz and 2.6GHz frequency bands, comb shaped with unequal rectangular arm dipole antenna which can be applied to 1.8GHz,2.4GHz,2.45GHz and 2.6GHz frequency bands , and comb shaped slot antenna which can be applied to 0.7GHz 0.9GHz and 1.8GH frequency bands.
In this study, the size parameters of comb shaped planar dipole antenna are changed to observe the impacts on antenna characteristics. After simulation, the better parameter values of dipole antenna are obtained and can be used in GPS,RFID,WLAN and LTE frequency bands.
The suitable size parameter L5=26.75mm of the comb shaped with uequal rectangular arm dipole antenna is obtained from simulated results. The proposed antenna can be used in RFID, WLAN and LTE frequency bands.
The comb arm size parameters of the dipole slot antenna are adjusted to observe the variations with respect to the bandwidth, resonant frequency and gain of the proposed antenna. The better size parameters L5=29mm and L6=15mm are obtained to fabricate the comb dipole slot antenna which can be used in LTE 0.7GHz, LTE 0.9GHz and LTE 1.8GHz frequency bands.
The proposed multiband dipole antennas by changing size parameters can be applied to GPS, WLAN, RFID and LTE frequency bands, respectively.

Key words：planar dipole antenna、comb shaped rectangular arm、needle arm、WLAN、LTE
