摘要： Planar or cylindrical phased arrays are two candidate antennas for future polarimetric weather radar. These two candidate antennas have distinctly different attributes when used to make quantitative measurements of the polarimetric properties of precipitation. Of critical concern is meeting the required polarimetric performance for all directions of the electronically steered beam. The copolar and cross-polar radiation patterns and polarimetric parameter estimation performances of these two phased array antennas are studied and compared with that obtained using a dual-polarized parabolic reflector antenna. Results obtained from simulation show that the planar polarimetric phased array radar has unacceptable polarimetric parameter biases that require beam to beam correction, whereas biases obtained with the cylindrical polarimetric phased array radar are much lower and comparable to that obtained using the parabolic reflector antenna.

摘要： This paper introduces a planar 4 × 4 slot antenna array based on Empty Substrate Integrated Waveguide at 28 GHz. The proposed antenna offers reduced weight and fabrication cost as well as relatively feasible integration with planar electronic components. The proposed antenna suggests an operating bandwidth of 7.8% (i.e. 27.1-29.3 GHz) suitable to fulfill demands of 5th Generation (5G) networks with high gain performance of 17.2 dBi and with reduced sidelobes level in the H-plan.
