This article presents a novel, compact, single feed circularly polarized (CP) microstrip antenna. Proposed design involve an inverted Y‐shaped radiating patch fed by an L‐shaped microstrip line feed and a rectangular open‐loop placed near its right corner. A semi‐rectangular ground plane is used on the opposite side of the substrate. Coupling between the rectangular open‐loop and the inverted Y‐shaped patch plays a vital role in attaining wideband CP, while the semi‐rectangular ground plane is crucial for enhancing impedance bandwidth (IBW). The optimized design achieved measured wide IBW of 5.164 GHz (65.53%, spanning over 5.297‐10.461 GHz) having its center frequency ( f rc ) at 7.878 GHz. The corresponding measured axial ratio bandwidth (ARBW) obtained inside the measured IBW curve is 2.25 GHz (having its center CP resonating frequency f cp 7.52 GHz, spanning over 6.40‐8.65 GHz, 29.92%). Measurement results are validated in both Ansys Electronics Desktop 2020 R1 and CST Microwave Studio 2018. Proposed antenna is fabricated on FR‐4 epoxy substrate of 1.6 mm thickness and exhibits a very small footprint of just 400 mm 2 (20 × 20 mm 2 ) (size 0.58 λ mgL × 0.58 λ mgL × 0.046 λ mgL , where λ mgL is the measured guided wavelength at lower resonating frequency f mrL = 5.297 GHz) with 51.31% reduction in size. Measured maximum peak gain for the impedance band is 2.04 dBi at 8.8 GHz and 1.96 dBi at f cp 7.52 GHz. The structure of the proposed antenna is extremely simple, quite small in size and its CP bands can be suitable for some C‐band and ITU (International Telecommunication Union)—8 GHz application.
