A compact microstrip patch antenna operating at 60 GHz is presented for short-range wireless and millimeter-wave sensing applications. The antenna is designed on a Rogers RT/duroid 5880 substrate with a relative permittivity of 2.2 and a thickness of 0.2 mm, resulting in a compact physical size of 8.12 mm × 3.48 mm × 0.2 mm. A modified patch geometry and microstrip feed structure are employed to achieve effective impedance matching and stable radiation performance at the target frequency. Simulations are carried out using Ansys HFSS to evaluate the antenna characteristics. The simulated results show a resonance at 60 GHz with a minimum reflection coefficient of approximately -24 dB and an impedance bandwidth of 0.92 GHz. The antenna exhibits a stable broadside radiation pattern with a peak realized gain of about 7.9 dBi and a front-to-back ratio exceeding 14 dB. These characteristics make the proposed antenna suitable for compact short-range wireless sensing systems operating in the 60 GHz band.

Abstract
A compact microstrip patch antenna operating at 60 GHz is presented for short-range wireless and millimeter-wave sensing applications. The antenna is designed on a Rogers RT/duroid 5880 substrate with a relative permittivity of 2.2 and a thickness of 0.2 mm, resulting in a compact physical size of 8.12 mm × 3.48 mm × 0.2 mm. A modified patch geometry and microstrip feed structure are employed to achieve effective impedance matching and stable radiation performance at the target frequency. Simulations are carried out using Ansys HFSS to evaluate the antenna characteristics. The simulated results show a resonance at 60 GHz with a minimum reflection coefficient of approximately -24 dB and an impedance bandwidth of 0.92 GHz. The antenna exhibits a stable broadside radiation pattern with a peak realized gain of about 7.9 dBi and a front-to-back ratio exceeding 14 dB. These characteristics make the proposed antenna suitable for compact short-range wireless sensing systems operating in the 60 GHz band.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
