Novel compact dual-band implanted antenna

This paper presents a compact implanted antenna operating at 0.915 GHz and 2.45 GHz. The antenna performance was investigated by simulation and validated with measurements. The antenna size is 1/25 λ at 915 MHz with a gain of -22.8 dB at 2.45 GHz and -27.3 dB at 915 MHz. The total efficiency achieved is -18.2 dB at 2.45 GHz and -21.8 dB dB at 915 MHz.
