Design narrow slot antenna for dual frequency

A planar ultrawideband modular antenna for connection to a feed network. The antenna has a ground plane, and an array of antenna elements spaced from the ground plane, each antenna element comprising a pair of arms.

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. Design of Narrow Slotted Rectangular Microstrip Antenna VSWR of the proposed antenna that is Owing to it objective is to design a reduced 1:1.03 at the resonant frequency 8.73 GHz. size wide band microstrip antenna; the Good broadside radiation pattern obtain in design idea was taken from broadband fig. 5. antennas to make the antenna work in a large band of frequencies of the many CONCLUSIONS ... Compact Rectangular Slot Patch Antenna for Dual Frequency ... This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12. Non-Resonant Slotted Waveguide Antenna Design Method High Frequency Design ANTENNA DESIGN where C 0 is a phase difference of currents feeding adja-cent slots, while d is a physical distance between these slots. One use for these antennas is in a thin array for radio-location devices. It is desirable in these applications to transmit and receive energy to and from a narrow sector of a free space.

Antenna designs were achieved for wideband operation by the use of a coplanar patch-slot antenna, fed by a coplanar waveguide. This design is easily tuned to operate at 2.45 and 5.75 GHz, with wide bandwidth for wireless systems. The oper- ating frequency is controlled by modifying the patch dimensions. Study and Design of a Differentially Fed Tapered Slot Antenna ... such antenna array concepts, thereby facing one of the biggest Abstract—The results of a parametric study and design of an ultra-wideband dual-polarized array of differentially fed Tapered Slot Antenna elements are presented. We examine arrays of bunny-ear antennas and discuss the capabilities and limitations of differential antenna technology. DUAL NOTCH LOADED MICROSTRIP ANTENNA FOR PENTA ... - 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).

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.
