A compact open-slot antenna for bandwidth enhancement is presented. Multiple resonances are generated by using an asymmetrical rectangular patchOn the other hand, some slot antennas have the limited bandwidth, which is not enough to use for more applications. To reduce an antenna size... Planar Antennas with Enhanced Bandwidth and... |… It is shown that this modification improves the fractional bandwidth of the antenna from 41 to 87%; in particular, the operational bandwidth of the proposed antennas is double that of aOpen access peer-reviewed chapter. Planar Antennas with Enhanced Bandwidth and Radiation Characteristics. A Large Bandwidth T-shaped Microstrip-fed Ground Plane … The impedance and bandwidth of the proposed antenna depend highly on the design parameters. The radiation resistance has a low value.In a conventional microstripline-fed slot antenna, a narrow rectangular slot is cut in the ground plane, and the slot is excited by a microstrip feedline with either a... Slot Boosts Bandwidth Of WLAN Patch Antenna |…

enhancing the bandwidth of antenna is proposed. This paper includes a wideband inverted slotted microstrip patch antenna fed by microstrip transmission lineBy incorporating extra E shape slots in radiating edges, the gain and cross-polarization has been improved. These techniques offer easy...

improve the gain and bandwidth of a slot antenna such as changing the feed dimensions, introducing a reflector [2]. Usually, loop antenna and slot antenna are the two classes of horizontally polarized antennas. In [4], a horizontally polarized Omni-directional loop antenna shows a desirable BANDWIDTH ENHANCEMENT OF MICROSTRIP LINE AND CPW-FED ... rectangular slot antennas to obtain broad impedance bandwidth along with stability of the radiation patterns. Dual resonance nature is observed in the asymmetric slot antenna and these resonances can be merged to achieve a higher bandwidth. The rectangular slot excited by microstrip line feed and CPW fed gives an impedance bandwidth

Bandwidth Enhancement of Cavity-Backed Slot Antenna Using ... Integrated Waveguide (SIW) cavity-backed slot antenna is presented. Bandwidth improvement is achieved by separating the resonant frequency of two ...

This paper presents the designing and analysis of a U-shape microstrip patch antenna. With the advancement in wireless communication technology, the requirement for lightweight and miniature size antennas has become a compulsory requirement …

Slot antenna Slot antenna with FSS (simulated).A second order, band pass frequency selective surface with large bandwidth combined with a wideband slot an-tenna has been studied and demonstrated successfully. Slotted UWB Antenna for Bandwidth and Gain Enhancement Capability of operating over wide frequency bands and good radiation characteristics lead to choosing a rectangular radiation patch as a basic structure of the slot antenna. Modifications have been applied to the radiation patch to manage the current distribution in order to achieve a wide bandwidth. Implementation of rectangular slit-inserted ultra-wideband… In this paper, a tapered slot antenna is designed and proposed. The antenna has a 3 dB beam width, high gain, and directive characteristics, which are appropriate for reducing the area of the antenna and for location recognition. The bandwidth was improved by inserting rectangular slits in the radiator of... Enhanced bandwidth slotted microstrip patch antenna
