This paper discusses the advantages and an example of using shaped elevation patterns for 5G base stations. A simple iterative power synthesis method involving the phase of shaped patterns, and suitable for both center- and end-fed sub-arrays, is used. Numerical simulations and some experimental results for an array of linear sub-arrays with...

The effect of forming single and multi-lobe beam<br/>patterns at mm-wave base station antennas on the received signal<br/>strength and co-channel interference is studied for mm-wave urban outdoor environments. A sample, simplified urban city model is used with randomly selected user positions. Ray tracing simulations are performed to analyze the...

The impact of reducing the total number of elements in passively-cooled, chip-integrated and space-tapered 5G base station antenna arrays on inter-beam interferences and chip temperatures is investigated for multi-user spacedivision-multiple-access applications. A convex element position optimization algorithm is used to synthesize the array...

The thermal and electromagnetic effects of varying the ground plane thickness and aperture size of the 5G integrated base station antennas are investigated. A double-sided PCB structure is designed with antennas and digital beamforming chips on the opposite sides. Fully-passive cooling is achieved by using fanless CPU coolers attached to the...

The performance of space-tapered multi-beam arrays with minimized side lobe levels is statistically evaluated in a line-of-sight propagation environment within a cell sector in terms of the signal-to-interference-plus-noise ratio at the multiple user ends. Comparative analyses are performed to examine the advantages of space-tapered, irregular...

A novel hybrid beamforming architecture based on aphased array of active multiport subarrays is proposed for multi-user 5G applications. The subarrays have multiple simultaneous fixed beams which are smartly combined at the user locations withrelatively large gains towards the intended co-frequency users and sufficiently low inter-user...

This paper presents a 5G downlink system model for a hybrid multi-user beamforming technique at the base station. The presented technique employs power flux equalization in the elevation plane using a fixed analog cosecant-shaped beam and digital beamforming in the azimuth plane. The system performances of various beamforming algorithms are...

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...

In this paper, we present a 5G base station phased antenna array concept based on the power equalization in the elevation cut. We designed aperture coupling microstrip patch array exploiting a substrate integrated waveguide structure as feeding line for realization of the cosecant radiation pattern in elevation cut. The antenna is designed to be...

A novel two-port, dual-band square-ring microstrip antenna element for wide-angle scanning planar phased array is proposed. The two ports are used to operate the antenna array over the L and S radar bands. Microstrip square-ring radiators are chosen due to their smaller dimensions compared to the conventional microstrip patch. To extend...
