“…The split ring resonator is self‐resonant and has a resonant frequency that is determined mainly by its loop inductance and the capacitances resulting from the cuts, which open the loop. The salient feature for the metamaterials is that the electrical size of a single unit cell is small compared to the wavelength; hence it can be effectively used for creating narrow band notches . The proposed structure is a single ring modified triangular split ring resonator with split at the end and a conductor extension inside the triangle as shown in Figure .…”

A compact microstrip fed novel U‐shaped fractal monopole antenna with enhanced bandwidth and band notched characteristics is presented for ultrawideband applications. The self‐similar fractal property is used in the U‐shape monopole to obtain 2n surface current paths to achieve good impedance matching over a wider bandwidth. A parametric study is performed to optimize the crucial antenna parameters. The proposed fractal antenna exhibits wider impedance bandwidth from 2 to 13.7 GHz for VSWR ≤ 2. By increasing the number of fractal iterations to three (n = 3), wider bandwidth of about 149% (impedance bandwidth ratio 6.85:1) is achieved with 43% improvement in impedance bandwidth. By etching a novel complementary split ring resonator in the ground plane, the stop band for wireless local area network and HIPERLAN/2 (5.15–5.825 GHz) system is obtained. The total volume of the presented antenna is 20 × 20 × 1.0 mm3 and the simulated and measured antenna characteristics are in good agreement. © 2015 Wiley Periodicals, Inc.

In this article, low-profile and compact cylindrical dielectric resonator antenna along with circular slots and filtering structure for wireless application is reported. Proposed antenna is excited by annular-shaped microstrip line. Two ring-shaped resonators placed on opposite sides of feed line are working as a band-pass filter. These resonators are unified with wideband cylindrical dielectric resonator antenna and make it suitable for triple band operations with better isolation level. Dual ringshaped parasitic slots on a partial ground plane are used to make CDRA more compact. The proposed triple band antenna has been analyzed, studied and optimized using Ansoft HFSS simulation software. Prototype of proposed geometry has been fabricated and tested. There is a better accord between simulated and measured results. The proposed design engenders three frequency bands i.e. 2. GHz with a resonant frequency of 2.45, 3.55, and 5.35 GHz, respectively. Proposed antenna design may find suitable applications for WLAN (2.4/5.2 GHz) and WiMAX (3.5 GHz) bands. The proposed design shows an average measured gain of 4.71 dB in the three desired bands.
