Abstract

A compact yet simple, printed monopole design targeted at providing multiband operation in the 2.4/5/6 GHz Wi-Fi 8 (2400-2484/5150-7125 MHz) bands and also the 5G new radio (NR79) (4.4-5.0 GHz) band and 6G upper mid-band in the 7.125-8.4 GHz range is demonstrated. The antenna is composed of longer and shorter radiating arms, as well as a matching stub that protrudes from the longer arm around the antenna port and extends toward the shorter arm. The two arms and the stub are all printed on a low-cost single-layer substrate. Four resonant modes of the antenna are excited, with the lower mode covering the 2.4 GHz band and the three upper modes forming a wide 7.4-dB return-loss bandwidth of about 4.3-8.6 GHz, covering the 5G NR79 band, 5/6 GHz Wi-Fi bands, and 6G upper mid-band. Additionally, the design can be fed by a commercially available coaxial cable, allowing the antenna to have considerable flexibility in installation within wireless devices.
