A Dual Notch Band UWB Antenna for Local Area Cognitive Radio Network Applications
نویسندگان
چکیده
Over the years, Cognitive radio technology has dramatically influenced wireless systems in which antenna plays a significant role for interviewing spectrum sensing and underlay operations. An ultra-wideband (UWB) with extended dual notch band feature is proposed this work to meet requirements of cognitive radios without interference from crowded spectrum. The consists stair-stepped rectangular patch circular cut off at lower edges complementary split ring resonator (CSRR) Patch Stub are loaded achieve bands. It an optimum dimension 18mm by 18 mm, fabricated on FR4 material operates between 2.64 GHz 11.87 two bands 3.293.61 4.956.05 GHz, respectively 5G carrier WiFi carrier. measured results show peak total gain 3.93 dBi more than 92% radiation efficiency entire operating range. This well suited Local area networks; simulated were found be good agreement satisfactory.

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

متن کاملClosely Spaced Dual Band-Notched UWB Antenna for MIMO Applications
A closely spaced dual-band notched UWB MIMO antenna is proposed in this paper. A traditional semi-circular monopole with ultra-wideband operation is chosen as an element of the proposed MIMO antenna. When two of the UWB monopoles are put together closely, the mutual coupling between them is apparently strong. To reduce the coupling between the antenna elements, a T-shaped branch is inserted bet...
متن کاملReconfigurable Notch Band Antenna for UWB Application: A Review
Microstrip Patch antenna is generally used in a number of antenna systems because of their low profile, light weight, low cost, compactness etc. Patch antenna is also used with Microwave IC’s and Monolithic Microwave IC’s because of its compatibility. Reconfigurable band notches in UWB antennas are dynamic research area. The advantage of the antenna with reconfigurable band notch is to efficien...
