چکیده
Abstract In this paper, we present a 28 GHz antenna array in package which covers the n257 and n258 frequency bands designated for 5G applications. The dipole is placed on one of two re-distribution layers fan-out eWLB (embedded Wafer Level Ball Grid Array) package. For TX RX, separate but identical arrays are each side die. paper presents novel horn-shaped heatsink not only dissipates heat, also improves radiation performance. four-elements has impedance bandwidth almost 6 (24–30 GHz) shows maximum realized gain 9.5 dBi. Beam-steering ± 35 deg achieved azimuth plane (H-plane) by providing different phases to dipoles through chip. measurements nicely agree with simulation results.

متن کاملA New Design of Log-Periodic Dipole Array (LPDA) Antenna
This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...
متن کامل28 GHz High Efficiency Planar Array Antenna with Hybrid Feed Network
Microstrip antennas and arrays have been widely used in military and commercial applications because of their ease of fabrication, low profile and low cost. In any microstrip array antenna, design of the feed network is always the most challenging task for which many different methods have been proposed. One method is to distribute the power to individual array elements by a coplanar microstrip...

متن کاملCompact Array Antenna: Omni-, Sector, and Adaptive Modes of Compact Array Antenna
Three working modes, omni-, sector and adaptive modes, for a compact array antenna are introduced. The compact array antenna is an electronically steerable parasitic array radiator (Espar) antenna, which has only a single-port output, and carries out signal combination in space by electromagnetic mutual coupling among array elements. These features of the antenna significantly reduce its cost, ...
