Design of a Dual-Band Microstrip Patch Antenna for GPS The dual frequency and wide-band operation of a trapezoidal patch with V-shaped slot have been studies and simulated. The proposed antenna is compact, occupies small volume and has simple structure compared to other antenna design. The antenna offer a 2:1 VSWR bandwidth of 4% from frequency range (PDF) DUAL NOTCH LOADED MICROSTRIP ANTENNA FOR … 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. Figure 5: Radiation pattern of DNSMSA measured at 4.85 GHz Figure 5 the far field co-polar and cross-polar radiation patterns of DNSMSA measured in … Design Narrow Slot Antenna for Dual Frequency - PIERS PIERS ONLINE, VOL. 3, NO. 7, 2007 1028 The radiation pattern on yz-plane and xz-plane at frequency 2.44GHz and 5.25GHz are shown in Figure 5 and Figure 6. 5. CONCLUSIONS In this paper, a narrow slot loop antenna and linear slot antenna were designed for dual frequency. Design Narrow Slot Antenna for Dual Frequency | Request PDF

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 .

Design of Asymmetric Slot Antenna with Meandered Narrow Design of Asymmetric Slot Antenna with Meandered Narrow Rectangular Slit for Dual Band Applications Raj Kumar1, *, Praveen V. Naidu2, and Vivek Kamble3 Abstract|A compact, coplanar waveguide (CPW) fed asymmetric slot antenna with dual operating bands is proposed. The slot is modifled rectangular in shape and asymmetrically cut in the ground plane.
Further, a 2×2 antenna array with such antenna element is designed at the centre frequency of 6.684 GHz for obtaining higher directive gain.
The Design II structure of antenna’s geometry is as shown in Figure 2(a). From the figure, there is a double C-shaped slot which create the additional of second frequency, then makes the antenna act as a dual-band antenna. Figure 2(b) shows the parametric study on the different patch width. Four different dimensions are Design of Miniaturized Dual-Band Microstrip Antenna for WLAN ... principle and method of microstrip antenna design. A broadband dual band printed antenna for WLAN is designed in Section 3. In Section 4, a dual frequency dual band microstrip antenna is designed, which is used to realize the dual band operation on the radiation side. Section 5 is the summary of the paper. 2. Design Theory 2.1.
To better explain the antenna design, Fig. 2 shows four evolution stages of the antenna. Initially, a square slot antenna with two CPW-fed ports are depicted as shown in Ant.1 of Fig. 2. It provides two operating bands at around 3.8 and 15.6 GHz with narrow impedance matching and only has linearly polarized feature. Design A Dual-Frequency Rectangular Patch Antenna ... The design graphs are then used to compute the dimensions of a rectangular patch and feed network for a dual-frequency antenna for use at 1.9 and 2.4 GHz. For the feed network, two transmission lines are used to connect the two edge feeds to an open circuit stub to match the antenna at the two frequencies.
