“…Due to these features UWB antenna is an active research topic in recent years for academia and industry people. The various printed UWB antenna are reported [2,3] and prevalent methods to increase impedance bandwidth are introduction of steps and triangle cut in partial ground plane [2,3]. In the UWB band, there are bands such as radiolocation system (RLS) band (3.1 ̶ 3.7 GHz) as per US National table of frequency allocation, wireless local area network (WLAN) for IEEE 802.11a (5.15 ̶ 5.825 GHz), and X-band satellite communication system (XSCS) band (7.3 ̶ 8.4 GHz) exists which can create interference with UWB system.…”

A novel hammer-shaped UWB printed antenna with triple notched stop bands is presented and fabricated on FR-4 substrate with size of 40×40×1.6 mm 3 . The proposed antenna is composed of hammer-shaped patch with Cshaped slot, U-shaped slot on feed line, and inverted stepped notch and bevel edges with pair of L-shaped slots in partial ground plane. The fabricated antenna is tested and obtained impedance bandwidth 2.89 ̶ 11.6 GHz with three notched stop bands 3.15 ̶ 3.7 GHz, 5.45 ̶ 6.8 GHz, and 7.5 ̶ 8.8 GHz, for radiolocation system (RLS), wireless local area networks (WLAN), and X-band satellite communication system (XSCS) bands, respectively. Moreover, the antenna result shows omnidirectional radiation pattern, average gain of 3.10 dBi over the whole UWB band except at the notched frequency bands.

Abstract-In this paper, an efficient spectral signature based chipless RFID tag is presented, where 4 N number of words can be coded using only N number of resonators. As data bit encoding element, the proposed tag utilizes a number of modified complementary split ring resonators (MCSRR). A novel resonance detuning mechanism proposed here allows the use of an MCSRR to independently encode two data bits instead of one bit. Compared with two separate rings based CSRR, the proposed MCSRR occupies 56% less area and also reduces the resonance bandwidth requirement by more than 60%. The multiresonator circuit and the UWB antennas are implemented on a thin (0.127 mm) substrate with only single sided metallization. The proposed tag has great prospect to yield an ultra-low cost chipless RFID tag that may replace barcode in the long run.

“…The omnidirectional monopole antenna is modified by adding different shapes of reflectors such as planar reflector [7], corner reflectors [8,9], curved reflectors [10], ring reflectors [11], and others to obtain the unidirectional or bidirectional beams. To enhance the bandwidth, the linear monopole is extended to surface monopole [12] or three-dimensional (3D) monopole [13][14][15]. To realize the bidirectional pattern along the UWB frequency range, this paper presents the circular disc monopole (CDM) excited rectangular ring antenna.…”

This paper presents an ultra-wideband (UWB) rectangular ring antenna excited by a circular disc monopole (CDM) with a conducting rod and two double ridges to radiate bidirectional pattern with constant beam direction along the entire UWB frequency range of 3.1-10.6 GHz. The conducting rod and double ridges at the upper wall of the ring are added to solve the tilted beam problem at the higher edge frequency whereas the double ridges at the lower wall are used to enhance the impedance bandwidth. The dimensions of the rectangular ring and the CDM are initially considered to achieve the bidirectional pattern with the suitable resonant frequencies and bandwidth. Then, the parameters of copper rod and two double ridges are determined by parametric study using CST Microwave Studio simulation software. The prototype antenna was fabricated, and the measured results show good agreement with the simulated ones. The obtained bandwidth of |S 11 | < −10 dB can cover the UWB frequency range as well as the bidirectional beam radiation with constant beam direction (θ = 0 • , 180 • and φ = 90 • ). The minimum and maximum measured gains are 3.1 dBi to 5.3 dBi, respectively. The proposed antenna possesses compact size with good radiation performance that can be a promising candidate for UWB applications.
