A compact microstrip planar antenna with asymmetrical slot width on single dielectric layer has been investigated for multi-frequency operation. The antenna is especially designed for 5G communication and WLAN communication. The geometry of the proposed antenna comprises of a single dielectric layer with a single radiating element, in which the rectangular patch is introduced with dual U-Slot to achieve multiple resonances. The antenna is excited by a transmission line feeding, presents on the same layer. The antenna first resonates at 4.2 GHz, later resonates at 5.2 and 5.8 GHz. Proposed patch configuration shows improved bandwidth of 180, 350, and 250 MHz with the offset transmission line feed and asymmetric slot. Both symmetric and asymmetric behavior of dual U slot has been studied. The antenna was fabricated using a single FR4 substrate of dimension 16 × 20 × 1.56 mm3.
