Design narrow slot antenna for dual frequency

Antennas Research Papers - Academia.edu

Further it can be noted that, DNSMSA shows virtual size reduction of about 13.01% which indicates the compactness of the antenna. Also, the frequency ratio f2/f1 of the antenna is found to be 1.70 which shows the flexibility in the design of dual and triple frequency antennas. Design of Dual-Band Microstrip Antenna with U-shaped slot resonant frequency. Design process For designing of a rectangular microstrip patch antenna with U-shaped slot as shown in Figure1 (a), we have to select the resonant frequencies and a dielectric medium for which antenna is to be designed. The side view of the microstrip patch antenna with coaxial feeding method is explained in Figure1 (b). Chapter 5 Impedance of Slot Antennas 5.1 Introduction narrow slot approximation is reasonably good as shown in Figure 5.3. Note that the series impedance of the slot varies slowly with respect to frequency and that the reactive part is fairly flat and is capacitive above resonance. When additional layers are added, (layer 2 is εrÊ=Ê2.4 and layer 3 is εrÊ=Ê13) where each layer is nominally Chapter 8 Slot Antennas - eetrend.com A slot-antenna design will often require that the slot be cut in something other than an extended flat sheet surface. Whatever the surface, the electric field will be normal every-where except in the region of the slot. The field due to the electric currents on this metal surface can be deduced from the exciting magnetic currents2 in the slot ...

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 .
