Broadband microstrip antennas with switchable polarizations
Bombale, Uttam Laxmanrao (Dhirubhai Ambani Institute of Information and Communication Technology, 2010)Microstrip antenna consists of a patch of metallization on grounded substrate. These are low profile, lightweight antennas, most suitable for aerospace and mobile application. They are replacing many conventional antennas ... -
Compact Circularly Polarized Tri-, Dual- and Single-Band Dielectric Resonator Antennas
Chaudhary, Pankaj Prabhubhai (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)The Dielectric Resonator Antennas (DRAs) have received wide attention due to low loss, high radiation efficiency, small size, wider bandwidth and simple feed network as compared to the microstrip antennas. Microstrip ... -
Design and analysis of distortion reduction techniques in direct conversion receiver
Shah, Milind S. (Dhirubhai Ambani Institute of Information and Communication Technology, 2017)Direct-conversion is alternative wireless receiver architecture to the well-established super heterodyne architecture. Direct-conversion receiver (DCR) can offer highly integrated, low-power and low-cost hardware Solutions ... -
Design and analysis of multiband fractal antenna
Dhoot, Vivek (Dhirubhai Ambani Institute of Information and Communication Technology, 2015)Miniaturized Multiband antenna design is an important and challenging task for communication industry. Several constraints like size, position of the antenna, feasibility, reflection coefficient, Specific absorption Rate ... -
Design and analysis of novel receiver front-end sub-systems in Ku-band for satellite applications
Patel, Sanket S. (Dhirubhai Ambani Institute of Information and Communication Technology, 2014)A novel receiver front-end; Low Noise Amplifier (LNA), mixer and Local Oscillator (LO); is designed and analyzed in Ku-band. Different design aspects of the subsystems along with the trade-offs and improvements are presented. ... -
Design and Performance Comparison of Novel High Q Coaxial Resonator Filter for Ka-band High Throughput Satellite
Dad, Vineet Kumar (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)The filters deployed in the satellite are high-performance filters that have very stringent in-band and out of band performance. They require high Q resonators with spurious free-range for their realization. But, the Q ... -
Efficient methodologies for package/housing effect on active MMIC and signal integrity problems
Sarvaiya, Ashish Kalubhai (Dhirubhai Ambani Institute of Information and Communication Technology, 2016)There has been a great demand in a Computer Aided Design (CAD) tool with a capability of design and analysis of gigahertz system having active Monolithic Microwave
