Abstract
In this paper, a circularly polarized broadbandslot antenna is designed for base station applications. Theantenna is built on a square-shaped FR4 Epoxy substrate thatmeasures 60mm in length and 1mm in height with a relativepermittivity of 4.4. The ground plane has a recessed slot, and thefeeding mechanism employs an offset microstrip line. The slotenables circular polarization and optimal impedance matching,which are enhanced further by offset feeding and the additionof stubs to create a composite-shaped patch. With an impedancebandwidth of 106% (1.28 GHz-4.16 GHz) and an axial ratiobandwidth of 69% (1.71 GHz-3.51 GHz), the CP broadband slotantenna effectively covers popular mobile communicationbands such as GSM 1800, GSM 1900, 3G/LTE 2100, 3G/LTE2300, 4G/LTE 2500, and 2.4 GHz Wi-Fi bands. The maximumgain is simulated to be 3.5 dB.
