Energy-Efficient RF for UDNs

Abstract

multi-standard RF front-end is a critical part for current and future mobile generations, where the size, efficiency and the integration of the elements in the RF front-end affect the expectations of the standard performance, This chapter discusses the design of power amplifier in both handset and base station of 5G and beyond. Also, this chapter deals with the filters, antennas, and the integration between these elements. A filter-antenna integration has been studied here. A synthesis-based approach has been followed for the filter-antenna codesign, moreover, design of a differentially driven reconfigurable planar filter-antenna integration with high-gain and high-common mode suppression is proposed for 5G RF front end systems. Finally, an insensitive phased array antenna with air-filled slot-loop resonators is introduced for 5G mobile communications

Synthesis and Realizability in Design of Minimum-Simulation Inline Antenna Arrays

“…For whatever choice of z I , S IC(n) can be computed as cascade of the input phase shifter and the known core (1), resulting in the needed Γ (n) M for input matching: Fig. 3.…”

“…In the current landscape of wireless telecommunications, phased arrays are gradually replacing some traditional singlefeed antennas such as parabolas and horns in several applications. Architecturally however, phased arrays demand multiple radio-frequency chains which are unpalatable where cost, consumption and number of components must be minimized and where dynamic beam steering is not required [1].…”
