16. Modeling of a Retrodirective Channel With Active Antenna Arrays for Cross-Eye Jamming
Abstract : Cross-Eye (CE) jamming is a technique aimed at inducing false target angles in radar measurements. The potential to deceive monopulse radar, a radar type commonly used due to its angular accuracy and resilience against jamming, has captured the interest of Electronic Warfare (EW) system manufacturers.

18. Modeling and Compensation of Nonlinear Distortion in Multi-Antenna RF Transmitters
Abstract : Multi-antenna systems are utilized as a way to increase spectral efficiency in wireless communications. In a transmitter, the use of several parallel transmit paths and antennas increases system complexity and cost. Cost-efficient solutions, which employ active antenna arrays and avoid expensive isolators, are therefore preferred. READ MORE

19. Antenna Limitations and Q-factor Trade-off between Parameters, Steps towards Optimal Antenna Design
Abstract : Sub-wavelength antennas have become ubiquitous in essential devices, such as mobile phones, sensors, Internet of things (IoT) and machine to machine (M2M) communication devices. Such antennas are often embedded as a small part of the device chassis or their circuit-boards. READ MORE
