Compact dual‐band antenna with slotted ground for implantable applications

Abstract

In this article, a miniaturized circular planar inverted‐F antenna (PIFA) is proposed for biomedical applications, operating in Medical Device Radiocommunications Service (MedRadio; 401‐406 MHz) band and Industrial Scientific and Medical (ISM; 2.4‐2.4835 GHz) band. It consists of a U‐shaped patch on top layer, a circular ground on bottom layer, and a shorting pin connecting two layers. By adding two sets of open‐end slots in the ground, dual‐band performance of the proposed antenna is achieved with compact size. Measurement result shows that a wide bandwidth of 41%, ranging from 345 to 510 MHz, can be achieved in MedRadio band, and a wide bandwidth of 27.8%, ranging from 1.92 to 2.60 GHz, can be achieved in ISM band.

Implantable Antennas for Bio-Medical Applications

“…Luo et al have designed a PIFA with slotted ground plane in [42]. The antenna makes use of 0.635 mm thick layer of Rogers 3010 (✏ r =10.2 and tan =0.005) as substrate and superstrate with an overall size of ⇡ ⇥ 5.35 2 ⇥1.34 mm 3 .…”

Systemic Overview of Microstrip Patch Antenna’s for Different Biomedical Applications

“…Ideally, the implantable antenna should have the slightly high signal waves as required outside the body because deep skin will absorb the signals ( Table 2 ) and hence, signal losses are possible before the message reaches to the receiver. 61 , 62 …”

X-Shaped Slotted Patch Biomedical Implantable Antenna for Wireless Communication Networks

“…These tissues have different dielectric properties which make it difficult for designing a biocompatible antenna to be utilized for the human body applications [6]. Many in-body antennas are designed for wireless communication at midradio band ranges between 402 and 405 MHz [7][8][9][10][11] and at ISM band ranges between 2.4 and 2.48 GHz [12][13][14][15][16][17]. A compact-sized broadband antenna for the implementations in biomedical implants operating at the MICS band (403 MHz) was presented in [8].…”
