This paper is about the investigation of a novel approach for establishing a data telemetry link in a dual-unit retinal prosthesis at microwave frequencies (1.4GHz and 2.35GHz) using a pair of Microstrip patch antennas. Approximately sized extraocular (25mm X 25 mm) and intraocular (6mm X 6mm) antennas are simulated using IE3D and compared with reference experimental results which was designed and fabricated using the Finite Difference Time Domain Method.

This paper presents a band notched WLAN self complementary ultra wide band antenna for wireless applications. The proposed antenna encounters a return loss (RL) less than -10 dB for entire ultra wideband frequency range except band notched frequency. This paper proposes a hexagon shape patch, edge feeding, self complementary technique and defective ground structure. The antenna has an overall dimension of 28.3 mm × 40 mm × 2 mm, built on substrate FR4 with a relative dielectric permittivity 4.4. And framework is simulated finite element method with help of high frequency structured simulator HFSSv17.2. the proposed antenna achieves a impedance bandwidth of 8.6 GHz, band rejected WLAN frequency range 5.6-6.5 GHz with vswr is less than 2.
