- Abstract
In this paper, patch antennas with elliptical slot and multiband features are introduced for sub-6 GHz 5G smartphones handsets. The aim of this work is to investigate the role that elliptical slots play in controlling the performance of patch antennas at sub-6 GHz frequency regime. Vertical and horizontal elliptical slots were used to study the effect of the slot direction on the antenna performance. Likewise, half vertical and half horizontal elliptical slots were used to observe the effect of the slot shape on the impedance matching and resonant frequency. The proposed antennas are simulated on FR-4 substrate with using CST Studio Suite software. Extensive simulations were carried out and two specific antennas were studied in details as case study. The first antenna (Antenna 1) incorporates a vertical elliptical slot and resonates at two frequencies (3.24 GHz and 4.95 GHz). The second antenna (Antenna 2) contains a horizontal slot and exhibits quad band performance with four resonate frequencies (0.69 GHz, 3.18 GHz, 4.65 GHz and 6.42 GHz). Both of the selected antennas were fabricated on FR-4 substrate and the measured results have shown good agreement with simulation results.
