Abstract: In this study, four novel microstrip antennas are designed for various wireless systems in two different types which are log periodic dipole array and planar monopole. In the first design, multiband behavior of standard printed log periodic dipole array antenna is converted to wideband by employing sub-sectional tapered feeding and the operating bandwidth is increased by using a feed point patch. By the way, the proposed antenna becomes capable of GPS (L1 and L2), PCS, IMT-2000, WLAN, WiMAX, UWB and X Band systems. The other designs are printed planar monopole antennas which have small size and low group delay. Microstrip inset feeding, sectional design and slot loading methods are basically used for these antennas. First printed planar monopole antenna is designed for WLAN, WiMAX, UWB and X Band applications by employing inset feeding and sectional design. In the second and the third printed monopole designs, slot loading technique is also employed. It provides both exciting extra resonance frequencies and keeping S11 performance below -10 dB level. In the second design, a novel slot geometry is implemented on the first printed monopole design for PCS band. Then, desired frequency resonance with required bandwidth is reached and the antenna becomes capable of PCS in addition to UWB and X Band. In the third design, another novel slot geometry is also implemented on the first printed monopole design for GPS band. Consequently, the antenna becomes capable of GPS in addition to WLAN, WiMAX, UWB and X Band.
