Design narrow slot antenna for dual frequency

By Admin


Effect of Capacitive loading on slot loaded Dual Band Microstrip antenna Mr. Prathamesh Bhat*, single-feed dual-band microstrip antenna loaded with narrow slots having capacitive loading has been studied which shows tuning and reconfigurability at the two frequencies 1.72 GHz and ... Dual-frequency antennas exhibit a dual-resonant behavior ... Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. Design and Analysis of Microstrip Monopole UWB Antenna the narrow impedance BW of these antennas. Some of the bandwidth enhancement techniques that are used to design planar antennas have been stated as below: Etching polygon-like slot antennas [2-8], modified elliptical antennas [4], using a fork-like tuning stub [5], and parasitic elements [11].

A design of broadband circular patch bandwidth (3-6)% [1,2]of the central frequency, its microstrip antenna with Diamond shape slot is given bandwidth is limited to a few percentage which by Garima, et al. [6].

Design of a new miniaturized FF-PIFA (Folded Fractal Planar Inverted F-antenna) with dual-band resonant behavior is introduced in this paper for use in the dual-band WLAN MIMO (multi-input multi-output) applications. slot array | Bandwidth (Signal Processing) | Antenna (Radio)

Dual Frequency Circularly Polarized Microstrip Antenna Fig 3. show the s parameter of the proposed design. This curve shows that the antenna resonate at two frequency.Fig 4 & 5 shows the Elevation pattern curve of dual frequency circularly polarized microstrip antenna at frequency 7.44 and 7.1 GHz respectivaly.Fig 6 shows the smith chart of the proposed design. Slot Antenna Uses Dual Polarization | Microwaves & Radio As will be shown, however, it is possible to obtain broadband frequency operation with a dual-polarized-antenna design. The antenna, excited by two coaxial-line feeds, is composed of four T-shaped slots and four cross-shaped slots in the radial directions of a circular patch.
