Slot and dipoles as dual antennas

11 May 2016 ... Abstract—A novel uniplanar slot dipole antenna fed by a coplanar waveguide ( CPW) is proposed for dual-band operation. The frequency ratio ...

A Compact Dual-Band Rectenna Using Slot-Loaded Dual Band ... 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 ... The slot antenna was designed from the intuition of Babinet's principle, that a horizontal electric dipole in free space is the dual of a vertical slot and will have the same radiation pattern as the slot of the same dimension. With the use of a A Compact Dual-Band Rectenna Using Slot-Loaded Dual Band ...

20 Aug 2018 ... complementary dipole/slot antenna array at the Ka-band using 3D ... an electric dipole, consisting of two metallic cuboids, was introduced to ...

Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

The band width of a narrow rectangular slot is equal to that of the related dipole, and is equal to half the bandwidth of a cylindrical dipole with a diameter equal to the slot width. Figure 2 shows slot antennas different from the rectangular shape that increasing the bandwidth of the slot antenna.

Slot antenna - Wikipedia A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna.
