“…Mahmood et al, 26 have used a hexagonal shaped slot in the radiating surface and likewise Jainal et al, 27 have used a slanting slot for developing the bandnotch characteristics. Two rectangular slits are inserted into the radiator for eliminating the WLAN band in, 28,29 respectively. Jangid et al, 30 have used rectangular shaped slot for obtaining single notch characteristics.…”

Ultra‐wideband technology has experienced a rapid growth over the last decade for its contribution in different sectors of human society. Printed antennas are considered as preferred platform for implementing this technology because of its alluring characteristics like light weight, low cost, ease of fabrication, integration capability with other systems, etc. Antennas developed for ultra‐wideband applications are desired to have notch characteristics for avoiding interference with other existing radio communication systems. The techniques related to design and developments of printed band‐notched antennas are continuously upgraded for improving the antenna performance. In this article, a comprehensive review has been carried out on ultra‐wideband antennas with band notch characteristics proposed in around last decade. The band notched UWB antennas available in the literature have broadly been classified into five different categories based on their notch characteristics like single band‐notch, dual band‐notch, triple band‐notch, quad/multiple band‐notch, and reconfigurable/tunable band‐notch, respectively. This review exercise may be helpful for beginners working on ultra‐wideband band‐notched antennas and also such a review process is not available in the open literature to the best of author's knowledge.

“…In response to such needs, several design approaches of flexible and conformal antennas based on flexible substrates were reported in the literature [33][34][35][36][37][38][39]. In [32], a flexible antenna printed on a 46mm x 30mm paper-based substrate was proposed for integration into flexible displays for WLAN applications.…”

Additional information is available at the end of the chapter http://dx.doi.org/10.5772/50841 . IntroductionRecent years have witnessed a great deal of interest from both academia and industry in the field of flexible electronics. In fact, this research topic tops the pyramid of research priorities requested by many national research agencies.According to market analysis, the revenue of flexible electronics is estimated to be billion USD in and over billion USD in [ ].Their light weight, low-cost manufacturing, ease of fabrication, and the availability of inexpensive flexible substrates i.e. papers, textiles, and plastics make flexible electronics an appealing candidate for the next generation of consumer electronics [ ]. Moreover, recent developments in miniaturized and flexible energy storage and self-powered wireless components paved the road for the commercialization of such systems [ ].Consistently, flexible electronic systems require the integration of flexible antennas operating in specific frequency bands to provide wireless connectivity which is highly demanded by today's information oriented society.Needless to say, the efficiency of these systems primarily depends on the characteristics of the integrated antenna. The nature of flexible wireless technologies requires the integration of flexible, light weight, compact, and low profile antennas. At the same time, these antennas should be mechanically robust, efficient with a reasonably wide bandwidth and desirable radiation characteristics.This chapter deals with the design, numerical simulation, fabrication process and methods, flexibility tests, and measurements of flexible antennas. As a benchmark, a flexible, compact, and low profile . µm printed monopole antenna intended for the ISM band applications at . GHz is presented and discussed in details. The antenna is based on a Kapton Polyi-

“…If the bandwidth of the antenna is wide, it becomes easier to operate at the target resonant frequency even if the characteristics change. A great deal of research has been carried out on wideband flexible antenna in the ultra-wideband (UWB), but the antenna operating in the UWB band does not operate in the WLAN band to avoid signal interference [4][5][6][7][8][9][10]. However, there are many wearable devices that use frequency bands such as WIFI and Bluetooth included in the WLAN band.…”

In this paper, we designed a flexible antenna operating in the WLAN/C-band/X-band and analyzed the antenna bending characteristics. It is advantageous to have a wide bandwidth because the resonant frequency of the flexible antenna can be changed when it is bent. The proposed antenna was designed based on a ring monopole antenna with broadband characteristics. Slots and t-strip lines to the ring, stubs to the feed, and stepped structures to the ground plane were added to increase bandwidth. As a result of analyzing the characteristics of the proposed antenna when bent through the S-parameter, it was confirmed that the proposed antenna is suitable at the target frequency, even if it is bent. The size of the antenna is 0.256 λ × 0.32 λ × 0.0016 λ () at 2.4 GHz, and the antenna bandwidth is 15.68% (2.36 GHz~2.87 GHz) at 2.615 GHz and 111.69% (3.4 GHz~12 GHz) at 7.7 GHz.
