Compact Size Triple Notched-bands UWB Antenna with Sharp Band-Rejection Characteristics at WiMAX and WLAN Bands

Abstract

In this paper, a compact triple band-notched Ultra Wideband (UWB) antenna with sharp band-elimination features and controlled notched bandwidths is proposed and discussed. The design is made up of a rectangular-shaped patch UWB planar monopole antenna with double collections of band-notched configurations. The band-notched configurations are involved to produce the desired lower and upper stop bands with good frequency selectivity and suitable stop bandwidths. The first notch is realized by using a C-shaped slot etched in the radiating patch in order to eliminate the interference at the WiMAX (3.4 - 3.8 GHz) applications. The second and the third notches are realized together by using a pair of U-shaped resonators that are located beside the feed line in both sides to eliminate the interference with the lower WLAN (5.15–5.35 GHz) and the higher WLAN (5.725–5.825GHz) bands. Additionally, the bandwidths of the lower and upper stop bands can be control separately by changing the parameters of the band-notched configurations. Furthermore, the suggested triple notched bands UWB antenna is optimized, fabricated, and measured for verification purposes. The measured results are close to the simulated ones.

A novel circular fractal ring UWB monopole antenna with dual band‐notched characteristics

“…Many triple-band notched antennas have also been developed using complementary split-ring resonator (CSRR), S-shaped slot and slot split-ring resonator (SSRR) pair [20], U-shaped slots [21], C-shaped slot and double U-shaped resonators [22], two pairs of nonuniform slots [23], and π-shaped and T-shaped slits [24].…”

Miniaturized Pentagon-shaped Planar Monopole Antenna for Ultra-wideband Applications

“…In current years, some antennas with sharp notch characteristics are being investigated. In [23], a rectangular antenna having size 47 mm × 38 mm can suppress the WiMAX band with a C-shape slot in the patch, and U-shape slot resonators present on both sides of the feed line provide sharp notches for lower WLAN (5.15-5.35 GHz) and upper WLAN (5.725 GHz-5.825 GHz). Thus, it provides sharp electivity, but spiculated notch does not solve the second problem.…”

Coplanar Waveguide-fed UWB Slotted Antenna with Notched-band Performance

“…However, there still exist some other narrowband communication applications which may cause electromagnetic interference with the UWB band such as the worldwide interoperability for microwave access (WiMAX) and the Wireless Local Area Network (WLAN) [7]. To handle this problem, several techniques, recently reported in the literature, have been applied by using different techniques such as slot resonators, complementary split ring resonators, split ring resonators, parasitic strips, Defected Ground Structures (DGS) and integrating filters with antennas [8,9].…”
