This paper presents millimeter wave phased array antenna for short range communication applications at 35 GHz. The antenna array is formed by 1 × 16 microstrip antipodal tapered slot antennas each connected to RF MEMS phase shifters for beam steering. The simulation and measurement results of the single antenna element are presented and the phase shifter structure to be used in the array is described...
A first-of-the-kind 28 GHz antenna solution for the upcoming 5G cellular communication is presented in detail. Extensive measurements and simulations ascertain the proposed 28 GHz antenna solution to be highly effective for cellular handsets operating in realistic propagating environments.
A retrodirective array (RDA) capable of retransmitting predictable polarization with respect to any received polarization state is presented. RDAs have the unique ability to scatter the received signal back to the interrogator without prior knowledge of the source location. In addition to this unique feature, the proposed system can receive any polarization and always retransmits the signal that is...
This paper describes the results of a project which is aimed at making a step change in AESA build technology by moving to a ‘tile’ technology to provide much lighter, cheaper arrays. The initial application is an affordable 2-D scanning array whose design goals were to achieve azimuth and elevation beamsteering with linear polarization over a 15%–20% bandwidth. The prototype antenna described here...
A 60-GHz band phased array transmitter is developed based on 90-nm CMOS process featuring compact baseband phase shifters with ideally zero power consumption. The phase shifter changes an RF signal phase every pi/2 by switching baseband signal paths. The transmitter has 6 RF front-ends and 6 phase shifters to implement beam steering function for a 1 times 6 array antenna system. Each of the RF front-ends...
