Ultra‐wideband monopole antenna for multiband and wideband frequency notch and narrowband applications

Abstract

A new design concept of a multi‐configuration antenna providing both frequency notched ultra‐wideband and multiple narrowband functionality from a coplanar waveguide fed circular monopole antenna is presented in this study. The proposed multiple antenna configurations are achieved by loading the feed section of the antenna with circular split ring resonator pair of varying dimensions and inner ring orientations and shorting copper strips. Fabricated prototypes were measured and compared with simulation and good agreement is obtained for both impedance and radiation characteristics.

A state-of-art review on band-notch characteristics in UWB antennas

“…In order to increase the applicability of UWB antennas and reduce the probability of potential interference from nearby narrowband communication systems, the UWB antennas with triple notch characteristics are extensively developed now‐a‐days. By etching multiple slots or installing multiple stubs parasitic elements triple notch characteristics is obtained …”

“…Based on the literature available here, triple band notch characteristics are realized on different antenna configurations with various techniques have been proposed at different frequencies. These band notched techniques are summarized in the Table with their cited reference.…”

Compact Uwb Antenna With Tunable Band-Notch Characteristics Using Varactor Diode

“…To avoid such potential interferences from these unwanted narrowband signals, band rejection features are required. In recent years, various design methods of UWB antenna with band-notch characteristic have been investigated [8][9][10][11][12][13][14][15][16][17]. Some conventional approaches carve differently shaped slots on radiating patches and adding stubs [8,9], insertion of resonator structures such as split ring resonator (SRR), CSRR, and electric ring resonator (ERR) [10][11][12], using parasitic strips [13] and Electromagnetic Band Gap Structures (EBG) [14][15][16][17].…”

“…However, UWB antenna's band-notched frequency [8][9][10][11][12][13][14][15][16][17] needs to be controlled and should be tunable to avoid fabrication errors and to meet the real-time reconfigurability. Thus, the reconfigurable technique has received considerable attention in wireless communications field.…”

Design of tri‐notched UWB antenna based on elliptical and circular ring resonators

“…To achieve this, different UWB antennas have been designed by utilizing different geometries for the radiating patch that is, Rectangular, 6 Circular 7,8 Elliptical, 9 fractal, 10 trapezoidal, 11 or hexagonal. 12 Single notch antennas for narrowband rejection, 6,8,9,[13][14][15] dual notch characteristics antennas, 7,12,[16][17][18][19][20][21] and tri-notch UWB antennas [22][23][24][25][26][27] have been designed and reported in the literature.…”
