This paper presents the design of a dual band rectangular Dielectric Resonator Antenna (DRA) coupled to narrow slot aperture that is fed by microstrip line. The fundamental TE 111 mode and higher-order TE 113 mode are excited with their resonant frequencies respectively. These frequencies can be controlled by changing the DRA dimensions. A dielectric(More)
This paper describes the design, manufacturing and testing of a new RFID chipless tag linearly polarized, with improved data capacity, reduced size. The tag generates data in the frequency band of 3.5-6.5 GHz. It consists of an H-shaped cavity and a circular UWB antenna associated by means of transmission line. An original shape and an original association(More)
In this paper a " Low Voltage, Low Power, High Speed and High Linearity-CMOS Analog Multiplier for Modem ASK is proposed ". The multiplier circuit is implemented in 180nm CMOS technology. It can be operated even at low Supply voltage VDD=0.9V. Band width of operation is about 4.10MHz, which is suitable for high frequency/high speed applications. This device(More)
—The impact of human body on the wireless communication systems is very required recently in indoor environments. The prediction of accurate and efficient coverage is more and more needed in the presence of various obstacles. This paper will present electromagnetic indoor propagation modeling with integration of human body, taking into account the nature of(More)
In this paper, a new compact Reader Antenna is designed and analyzed in European UHF RFID band (i.e., 865MHz - 868MHz). The proposed Dielectric Resonator Antenna (DRA) is composed of microstrip line/slot feed and a half dielectric resonator made from a high-permittivity (εr = 30). The simulated results show satisfactory performance versus size. The(More)
