“…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.

“…15-5.825 GHz band assigned for IEEE802.11a and HIPERLAN/2 and 7.35-7.75 GHz band for downlink of X-band satellite communication systems. In recent years different strategies have been investigated to reject such frequencies [4][5][6]. Introducing slot is a very popular and easy approach in this regard.…”

“…Omega-slots have been introduced in the patch close to each other to bring about band notch characteristics. In comparison to [17] the proposed antenna provides better bandwidth performance and in comparison to [4][5][6], it provides strong radiation attenuation at the notch bands. However, in literature various antennas are reported with dual, multiple band notch characteristic [9,13] but their gain performances are low with respect to the proposed antenna.…”

Abstract-This paper presents the development of an Ultra Wide Band (UWB) monopole antenna with dual band notch characteristics. Modified crown-square shaped fractal slots in the ground-plane are implemented to enhance the impedance bandwidth to around 58% as compared to conventional square monopole antenna without slots. Impedance bandwidth of the proposed antenna is approximately 114% with Voltage standing wave ratio (VSWR) < 2. In addition to this, two omega-shaped (Ω) slots have been incorporated in the radiating patch to render band-notch characteristics centered at 5.5 GHz band assigned to IEEE802.11a and HIPERLAN/2 as well as X-band for satellite communication centered at 7.5 GHz band. Measured antenna gain is stable over the entire UWB region except at the notch bands. Radiation pattern of the antenna show that the proposed antenna exhibits nearly monopole like E plane radiation patterns and omni-directional H plane radiation patterns throughout the band. A fabricated prototype is developed with close agreement between simulated and measured results.

“…In an UWB communication system one of the key issues is the design of a compact antenna while providing wideband characteristic over the whole operating band [2]. Considering the requirements of size, cost and performance， the design of a wideband antenna is a very difficult task.…”
