The biconical dipole antenna is frequency independent antenna. A dipole antenna is a narrowband and frequency dependent. In this paper a linear array of five biconical antennas with cone angle 30 is modeled in WIPL-D software and analyzed. Radiation pattern, gain, impedance and Sparameter plots of the array are analyzed and presented for 1-5 GHz frequency range. Mathematical equations for the parameters...
Image registration is the process of overlaying two or more images of the same scene taken at different times, from different viewpoints, and/or by different sensors. It geometrically aligns two images the reference and floating images. Medical image registration concentrates on aligning two or more images that represent the same anatomy from different angles and are obtained at different times. In...
The Multiple Input Multiple Output (MIMO) radar concept exploits the independence between signals at the array elements unlike beamforming which presumes a high correlation between signals either transmitted or received by an array. Radar Cross Section (RCS) of a complex target varies with both transmitted frequency and target geometry. By widely separating transmit and receive antennas, MIMO radar...
A digital phase-locked loop (DPLL) is designed using 0.18 mm CMOS process and a 3.3 V power supply. It operates in the frequency range 200 MHz-1 GHz. The DPLL operation includes two stages: (i) a novel coarse-tuning stage based on a flash algorithm, and (ii) a fine-tuning stage similar to conventional DPLLs. The flash portion of the DPLL is made up of frequency comparators, an encoder and a decoder...
The modern antenna design structure requires lowloss, low-dispersion, dimensional robustness and design flexibility. Continuous Transverse Stub (CTS) is an antenna technology that offers greater tunable bandwidth than waveguide or Microstrip patch antennas. This paper proposes a newer design of Continuous Transverse Stub (CTS) antenna The two major problems arises, while designing large bandwidth...
