چکیده
This article proposes, single feed compact slotted patch antenna. It can be seen that bandwidth of Microstrip antenna is increased up to great extant by cutting two equal slots which are same as π structure added with rectangular slots. In some applications in which the increased bandwidth is needed, designed antenna is one of the alternative solutions. The proposed antenna operates in frequency band (1.88-3.44 GHz) the fractional bandwidth is 58.88%. The gain has been improved up to 5.11dBi, directivity 5.39dBi and efficiency 97.216%. The proposed Microstrip antenna is fed by 50Ω Microstrip feed line .The designed structures and performance of different structures are simulated and compared by using IE3D Zealand simulation software based on method of moments.

متن کاملDesign and Simulation of Circularly Polarized Compact Microstrip Patch Antenna for C-Band Applications
Abstract—A probe-fed, slotted rectangular patch antenna has been proposed. Bandwidth enhancement has been achieved by suitably cutting slots into the rectangular patch, and efficiently exciting the slot by short circuiting the conducting patch through the dielectric substrate beyond the edge of the slot. Proposed antenna is suitable for various ground based and airborne applications in C-Band. ...
متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...
