Design narrow slot antenna for dual frequency

By author

A novel reconfigurable dual-band patch antenna design using a varactor-loaded slot has been proposed. The frequency ratio tuned from 1.35 to 1.73 with capacitance varying from 0.5pF to 1.1pF. The radiation patterns are similar at both bands. When C = 0.5 pF, the realized broadside gain at both bands is 7.2 and 7.5 dBi, respectively.

A planar array antenna having radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns. A distribution network, which is connected to each dual polarized … Radar Basics - Slot Antennas Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. Design of dual and Wideband Rectangular Patch Antenna for C and… For that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized. EUMA Frequency- and time-domain characteristics as well as indoor propagation channel impulse response of a compact dual band-notched ultra-wideband (UWB) slot antenna are investigated in this paper.

In the proposed antenna design, a combination of dual U-slot and multiple layers is used to ... Design of multi-band microstrip patch antennas even with narrow ...

CIRCULAR MICROSTRIP SLOT ANTENNA FOR DUAL- FREQUENCY RFID ... favorable to design a single antenna which operates on both frequency bands. A variety of dual-band slot loaded antennas have been reported in [26{28]. The dual-frequency characteristics have been demonstrated owing to a pair of slot is placed close to the radiating edges. However, the proposed antenna utilizes probe feeding that results in narrow Dual-frequency slot-loaded rectangular microstrip antenna In thi s sllldy, dual-frequency slot-loaded rectangular microstrip antennas were designed, fabricated and evaluated. The design consists of rectangular patch microstrip antenna loaded with a pair of narrow slots parallel and close to the radiating edges on the patch, which is feel by centre-fed microstripline feed .
