A Miniaturized Wideband Floret - Monopole Antenna for C Band Applications

Due to its low power consumption, the ultra wideband floret monopole antenna discussed in this article is intended for short-range communication. Three florets were arranged symmetrically on the top substrate surface to increase gain and efficiency. Simulation software (HFSS) was used to analyse the florets’ features. To increase the impedance bandwidth, the substrate’s bottom is provided with a partial ground. Broadband applications are served by the proposed antenna’s simulated impedance bandwidth, which ranges from 4 to 9 GHz. It is built on a low-profile, inexpensive FR4 substrate. The antenna’s total measurements are 20 x20x0.8m$\mathrm{m}^{3}$. The antenna has a maximum gain of 2.74 dB and emits omnidirectionally at a frequency of 6 GHz. The suggested miniaturized antenna supports 5G LTE (4,S-5 GHz), WiFi 7, and C band (4-8 GHz). Applications involving many frequencies can use the antenna.
