“…In other words, this may be conveniently considered as an array of arrays. Some recent research on Sierpinski carpet arrays, multiband arrays, fractal ultra-wideband arrays, super wideband antennas gives promising and excellent results for the application of fractal concept in antenna arrays [11][12][13][14][15][16]. The different types of fractal antenna arrays include cantor recipe set for linear fractal antenna array, planar Sierpinski carpet array, triangular, square and hexagonal antenna arrays.…”

Abstract-Fractal antennas have undergone dramatic changes since they were first considered for wireless systems. Numerous advancements are developed both in the area of fractal shaped elements and fractal antenna array technology for fractal electrodynamics. This paper makes an attempt of applying the concept of fractal antenna array technology in the RF regime to optical antenna array technology in the optical regime using nonlinear array concepts. The paper further discusses on the enhancement of nonlinear array characteristics of fractal optical antenna arrays using nonlinearities in coupled antennas and arrays in a conceptual manner.

“…So far, different notch band UWB antennas are reported in the literature . Fractal geometry‐based notch are etched from the monopole of the antenna to achieve the band rejection in UWB band . The analysis and design of these antennas is difficult because of their large structure and complex design.…”

In this article, a compact octagonal‐shaped UWB antenna with Minkowski fractal‐shaped notch and a dual C‐shaped notch is presented. The Minkowski fractal helps to obtain band rejection at WiMAX (3.4–3.7 GHz) band, whereas dual C‐shaped notch on either side of feed line provides the band rejection at WLAN (5.15–5.825 GHz) band. Moreover, a rectangular slot is also inserted in the ground plane, which helps to obtain the desired UWB bandwidth. The proposed antenna has the compact size of 26 × 16.5 mm2. The proposed antenna shows proper impedance matching, stable radiation pattern with good antenna gain (2–5 dBi) over the entire UWB frequency range. © 2015 Wiley Periodicals, Inc.

“…Several methods have been used to disturb the surface current of the antenna in order to drop the radiation in a favorable range of frequency bandwidth. One of them is etching slots or slits on the radiating patch [4][5][6][7][8]. Other methods are implementation of stubs, parasitic elements, and compact resonance patches, which unfavorably increase the size of antenna [9,10].…”

This paper introduces a new volumetric conical notch-band antenna. Structure of this antenna is in contrast with planar and printed band rejection antennas currently existing in almost all of the literatures. The radiation pattern of the proposed antenna is symmetrical and stable against frequency variation, while planar and printed antenna types suffer from high variation of their radiation pattern with frequency, and consequently asymmetric and unstable omnidirectional behavior. The frequency band of the antenna is notched with two slots implemented on the antenna structure. Uniform various frequency band rejections are achieved by changing the slots dimensions and position. Both measured and simulation results of manufactured antenna show the frequency bandwidth of the antenna is from 3 to 4.9 GHz and from 6.2 to 11 GHz with reflection coefficient less than −10 dB. Moreover, the antenna notches the frequency band from 4.9 to 6.2 GHz with nearly uniform reflection coefficient level of approximately −3 dB. Stable radiation pattern and proper range of frequency band rejection make the designed antenna an appropriate candidate for the use in UWB and indoor communication systems.
