Slot and dipoles as dual antennas

Antenna selection guidelines - STMicroelectronics

Dual Pol - National Oceanic and Atmospheric Administration array antennas for weather applications is the radiating element’s cross pol performance over the scan volume. This poster will present a slot-dipole dual polarized radiating element design and performance. A panel of 144 dual pol elements was fabricated and characterized in the far field RF anechoic chamber to demonstrate Slot Antenna The dual of a slot antenna would be if the conductive material and air were interchanged - that is, the slot antenna became a metal slab in space. An example of dual antennas is shown in Figure 2: Figure 2. Dual antennas - (left) the slot antenna, (right) the dipole antenna. Reconfigurable Microstrip Double-Dipole Antennas for Personal ... slot antennas fed by slotlines or CPW is presented in [7]. A reconfigurable patch antenna is obtained in [8] by in-serting slits at the non-radiating edges of the patch. A reconfigurable Yagi antenna is presented in [9] to operate at 2.4 and 5.78 GHz for wireless communications. A reconfigurable slot dipole antenna was presented in [10] in the ...

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 present invention is directed toward a dual linear or circular polarized antenna comprised of two orthogonally linearly polarized radiative elements. More specifically, the present invention is for a slender slot-dipole antenna, where the slot and the dipole are located in the same physical structure. Feed line interference to the antenna can be eliminated by including a centrally located ... Broadband Slotted Coaxial Broadcast Antenna Technology the slot. Babinet’s principle, put into antenna terms by H.G. Booker in 1946, relates the fields and impedance of an aperture antenna to its dual [3]. The dual of a slot would be a dipole as shown in Figure 3. Figure3: Dual antennas, (left) slot antenna and (right) the dipole antenna. 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 ...
