“…For UWB systems, printed monopole antennas with various radiation patch shapes are widely used due to their advantages of low cost, light weight and ease of fabricating and integrating with electronic devices [1][2][3][4][5][6][7][8][9]. In order to support multiple communication services in a single device through UWB and other communication systems, a single antenna that has the ability to operate in all these frequency bands is highly desirable.…”

Abstract-Three notched bands are generated, at selected frequencies, in an extremely wideband base antenna to support multiple communication systems while avoiding inference from other existing narrowband systems. The design of a fully printed extremely wideband antenna and creating triple band-notched functions are addressed in this paper. Measurements demonstrate that the proposed printed base antenna has an extremely wide 2 : 1 VSWR bandwidth from 0.72 GHz, to 25 GHz with a ratio bandwidth of 34 : 1. The antenna has a simple structure and can be fabricated at low cost for multi-band and wideband wireless communication devices. Besides, this paper presents a technique to form three notched bands within the operating frequency range of the base antenna. By introducing a half-wavelength U-shaped defected ground structure (DGS) and a pair of quarter-wavelength open arc-shaped slots to the radiating patch, three notched bands are created to prevent interference from WLAN (2.4-2.484 GHz and 5.15-5.85 GHz) systems and downlinks of X-band satellite communication (7.25-7.75 GHz) systems.

Abstract-Chipless ultra-wideband (UWB) has been proposed as a low-cost alternative for radiofrequency identification (RFID). In this paper, a comprehensible theoretical introduction to time-domain operation of a UWB RFID tag is described, and a circuit model is proposed. For commercial applications low-cost RFID readers are demanded. To this end, this paper addresses the measurement of time-coded UWB chipless tags for RFID in time domain. Two different setups to detect time-coded tags are presented, one based on commercial UWB impulse radar (IR) and the other based on a vector network analyzer (VNA). The experimental results show the feasibility of using an IR-UWB radar as a UWB RFID reader, achieving very good read ranges.

“…The reduction of the structural term of the antenna Radar Cross Section (RCS) involves the shaping of the target surfaces [1,2] and the use of Radar Absorbing Materials (RAMs) [3][4][5][6][7][8][9][10][11]. Indeed, it is well known that the antenna RCS significantly contributes to the overall RCS signature of target objects such as naval ships and airborne vehicles.…”

Abstract-An efficient strategy for reducing the signature of an antenna is to substitute the conventional solid ground plane with a patterned ground plane thus letting the incoming energy to pass through the structure except over the operating band of the antenna. However, in a real environment, the energy flowing through the FSS (Frequency Selective Surface) can be intercepted by eventual scatterers located behind the antenna, so to nullify the RCS (Radar Cross Section) reduction. To overcome this drawback, a novel composite structure is proposed which is able to dissipate such energy by placing a thin absorbing layer below the FSS ground. It is shown that a careful analysis has to be performed to accomplish this goal since the transparent antenna array and the backing absorber strongly interact and thus they cannot be separately designed. The optimal value of the foam spacer thickness between the FSS ground and the absorbing layer is investigated by an efficient equivalent transmission line approach. Criteria for enlarging the low-RCS band with respect to the free space design are also provided. An antenna array prototype backed by the thin multilayer structure is finally manufactured and tested.
