A Design of Crossed Exponentially Tapered Slot Antenna With Multi-Resonance Function for 3g/4g/5g Applications

Abstract

In this research work, a planar crossed exponentially tapered slot antenna with a multiresonance function is introduced. The presented antenna design is ascertained on a low-cost Rogers 5870 dielectric with a circular schematic. The antenna is designed to support several frequency spectrums of the current and future wireless communications. The configuration of the design contains a pair of crossed exponentially tapered slots intersected by a star-shaped slot in the back layer and a bowtieshaped radiation stub with a discrete feeding point extended among the stub parts. The crossed exponential slots exhibit a wide impedance, and the star slot generates an extra resonance at the upper frequencies. For S 11 ≤ −6, the antenna provides a wide operation band of 1.7 to 5.9 GHz supporting several frequency bands of 3G, 4G, and 5G communication. The fundamental characteristics of the proposed slot radiator are studied, and good performances have been achieved.

Dielectric-Insensitive Phased Array With Improved Characteristics for 5g Mobile Handsets

“…The fifth-generation (5G) wireless network has received a lot of attention from both academia and industry with many reported efforts [1][2][3][4][5]. It is expected to have significant improvements in terms of transmission rate, mobility,latency, and so on [6][7][8]. Compacted with 3G/4G communications, one of the main challenges in 5G networks is to shift to the higher frequencies(beyond 10 GHz) where it is easier to obtain wider impedance bandwidths and higher data rates [9][10][11][12].…”
