Abstract: A compact dual-band rectenna operating at 915 MHz and 2.45 GHz is presented. The rectenna consists of a slot-loaded dual-band folded dipole antenna and a dual-band rectifier. The length of the proposed antenna is only 36.6% of the half-wavelength (λ 0 /2) dipole antenna at 915 MHz while keeping dual-band property at 915 MHz and 2.45 GHz. The rectifier circuit is optimized for low ... (PDF) Design and Development of a 2.4 GHz Slot Antenna ...

CPW-Fed Stub-Loaded Slot Dipole Antenna Design Abstract—A novel uniplanar slot dipole antenna fed by a coplanar waveguide (CPW) is proposed for dual-band operation. The frequency ratio between the rst spurious and fundamental modes of the slot dipole antenna can be conveniently adjusted with the use of four slot stubs introduced on its two arms.

problems for the wideband dual-band dual-polarized antenna. In recent years, several dual-polarized antennas with good performances were designed based on slot antennas [3,4] and dipole antennas [5,6]. Several studies have been focused on the development of dual-band antenna elements [7{16].
