This work presents a circular planar antenna with reconfigurable radiation pattern using parasitic patches. The of the proposed may take different modes. mode change is made PIN diodes connected in gap between central patch and A short circuit or an open can be provided by this gap. works at 5 GHz, such as 802.11a/d/n applications. goal to provide wider coverage redirecting main lobe controlling beam directions avoid interference surrounding signals.
The present work demonstrates the design of a wideband 2 ×1 reconfigurable beam steering array for wireless communication systems.The designed antenna is powered by microstrip line and consists two rectangular-shaped radiating elements rectangular planar ground.Its dimensions are as follows: 0.67λ0 × 0.53λ0 0.03λ0.It executes three operating states turning on off PIN diodes to change direction main beam, well tilt ranging from (±30 • ) (±38 ).A progressive analysis in order enhance...
An Ultra-wideband (UWB) patch coplanar waveguide (CPW) antenna with tri band notched has been presented. The proposed consists to insert two different forms of slots in order obtain triple-band-notch characteristics. By using C-slots on the radiating bands are achieved at 3.5 GHz for Worldwide Interoperability Microwave Access (WIMAX), and C-band satellite communication systems 7.5 GHz. A spiral shaped slot is etched feed line another Wireless Local Area Network (WLAN) 5.8 design uses FR-4...

A compact ultra-wideband (UWB) monopole antenna with reconfigurable dual band-notch characteristics is exhibited in this paper. It consisting of a reshaped rectangular patch partial ground plane including slot. The property at WiMAX [3.3-3.6] GHz and WIFI 6E [5.925-7.125] bands, are achieved by associating three open-ended slots on the radiating patch. for purpose achieving performance, metallic switches inserted slots. Switching or off strips enable disable bands notched thus...
