[IEEE 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - Atlanta, GA, USA (2019.7.7-2019.7.12)] 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - A Substrate Integrated Waveguide Filtering Slot Antenna Array
摘要： A fully integrated 1×4 filtering linear antenna array is presented in this work. The filtering array is designed in substrate integrated waveguide technology and consists of 5 coupled cavities with a 6th-order filtering function. The antenna array is formed with a linear arrangement of four slot antennas in the final cavities which excite two modes in the radiating cavity. The array operates at a center frequency of 6.75 GHz with a fractional bandwidth of 5.0% and with a gain of 7.44 dBi.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Synthesis of Multiple Beam Linear Arrays with Uniform Amplitudes
摘要： A convex iterative algorithm for the synthesis of uniform amplitude, space-tapered linear phased arrays with simultaneous multiple beam optimization for 5G applications is presented. The performance of the algorithm is demonstrated by the synthesis of two arrays having 16 and 24 elements with 60 and 90 degree scan range, respectively. The effect of phase shifter quantization is also addressed. The results indicate that the space-tapered arrays with multiple beam optimization have improved radiation performance in terms of the side lobe level when compared to both single, broadside, beam optimized space-tapered arrays and uniformly distributed arrays with half wavelength spacing.
