Abstract—In this paper, a printed slot antenna fed by a co-planar waveguide for ultra wide bandwidth (UWB) with dual notch bands has been presented and discussed. The band notches are realized by etching one C-slot resonator inside a plaque shape exciting stub as well as symmetrically adding a pair of open-circuit stubs at the edge of the slot resulting in dual stop band filtering properties fo...

Broadband microstrip antenna is more commonly realized by cutting slot inside the patch. While designing slot cut antennas at a given frequency, slot length is taken to be either quarter wave or half wave in length. However this simpler approximation does not give closer result. In this paper, an analysis to study the effect of slot like, half U-slot and rectangular slot on the broadband respon...

Dual operations of AC current sensing and Bluetooth transmission using a reconfigurable slot antenna are described here. The novel setup comprises tunable connected to transformer AC/DC converter create smart mechanism. consists double-layer on thin, flexible substrate with tuning circuit consisting capacitive-coupled biasing tracks the backside. Capacitive coupling isolates circuits at DC whil...

The intent of this paper is to compare two designs of RFID antenna which is used for Ultra High frequency (UHF) and Ultra wideband (UWB) applications. Here the comparison of Hybrid design and XETS design is done. In hybrid design the antenna simultaneously operate on both the bands viz.UHF as well as UWB. In XETS design antenna operates only for UWB. Hybrid antenna is planar antenna. There is a...

In this paper, a parametric study of conventional Uniplanar Compact Photonic Band Gap (UC-PBG) structures, with different dimensions, is investigated. The studied structure operates as an Artificial Magnetic Conductor (AMC) in which the performance is mainly characterized by the resonant frequency and bandwidth. Simulation and numerical analysis have been carried out using CST Microwave Studio ...

An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...

We describe a new dual-polarized slot antenna to be used with quasi-optical devices such as superconductor-insulatorsuperconductor (SIS) mixers at millimeter and submillimeter wavelengths. The radiation and impedance characteristics of the antenna were obtained from a moment-method calculation. The antenna has an excellent radiation pattern, a low impedance, wide bandwidth, and low cross polari...
