Abstract
A rectangular meandering-microstrip patch antenna (RM-MPA) with shorting pin for implant antenna and biomedical applications at industrial, scientific, and medical (ISM) band is proposed. The rectangular patch has length of l =14 mm and width of w =9.4 mm. The substrate and superstrate are made of Rogers 3210 with dielectric constant equals 10.2. The RMMPA is placed between the substrate and superstrate dielectric layers whose same thickness equals 0.635 mm. The proposed antenna is fed by a 50-ohm coaxial probe, at the centre of the length and edge of the width of the patch. The input impedance of patch antenna varies with the patch geometry. Thus, the geometry of the patch changed to achieve impedance matching at ISM band. The rectangular patch divided to three sections along width for meandering. The resonance frequency is tuned by meandering each section. The proposed antenna is simulated in free space and skin phantom. Proposed antenna has efficiency of 90%, bandwidth 1.02%. Both radiation pattern and SAR are evaluated which SAR level is below the safety and satisfies SAR standards. Finally, the antenna is tested in minced meat and tissue liquid.
