Compact triple-band monopole antenna with anti-symmetric L-shaped branches for IoT applications on LTE/Wlan/Wimax/5G NR/V2X/WiFi 7 network
Abstract
A compact monopole antenna designed for triple-band functionality in multiple application networks is proposed. This antenna simply contains a pair of antisymmetric L-shaped branches and is constructed on FR4 substrate, which occupies only a miniature volume of 10×20×1.6 mm3. By properly designing the branches based on multiple harmonic resonance, three impedance bands including 2.35-2.7, 3.3-3.7, 5.05-9 GHz can be completed with this antenna. The antenna's resonant characteristics can be easily adjusted by changing the lengths and widths of its branches. With a compacted size and suitable radiation performance, the suggested monopole antenna may well work as an internal antenna for LTE/Wlan/Wimax/5G NR/V2X/WiFi 7 band wireless applications.
