چکیده
A small 3-Dimensional (3-D) multi-band antenna of “F” shape is proposed for portable phones’ applications. The designed configuration of the proposed antenna is different from traditional Planar Inverted-F Antenna (PIFA) radiators. The proposed antenna has the good characteristics of wide band. The ratio of impedance bandwidth to the central frequencies 2.5 and 5.1GHz is 28.6% and 9%, respectively. It can be applied to Bluetooth (BT) 2.4GHz and Unlicensed NII — 5GHz, UNII-1 5.1 ∼ 5.25GHz and UNII-2 5.25 ∼ 5.35GHz. The experimental results have fairly good agreement with the simulation data by High Frequency Structure Simulator (HFSS).

Modified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...
