“…In this frame, a wide range of antennas has been recently reported for bodyimplantable capsule applications, e.g. [9]- [17]. Robustness to heterogeneous and uncertain electromagnetic (EM) properties of tissues was considered in [18]- [21], and a reconfigurable capsule-conformal antenna without nulls in its radiation pattern was proposed in [22].…”

Wireless implantable bioelectronics and accurate in vivo characterization of path loss require efficient and robust in-body antennas. Loading electric antennas with the effective permittivities higher than that of surrounding tissues is a promising solution. In this study, proof-of-concept conformal microstrip antennas are proposed. The antennas are optimized for a standard impedance of 50 Ω and operate in all high-watercontents tissues. Integral ground plane shields the antenna from inner circuitry. The radiation efficiencies are 0.4%, 2.2%, and 1.2% for the (434, 868, and 1400)-MHz designs, respectively, when computed in a 100-mm spherical phantom with muscleequivalent properties. The efficiencies are compared to the fundamental limitations and closely approaches them. Specific absorption rates are evaluated, and the corresponding maximum input power levels are established. Prototypes are fabricated and characterized to validate the design.

“…To meet strict demands posed on implantable antenna design such as compact size, large bandwidth and low‐specific absorption rate (SAR), structures like dipole, helical and planar inverted‐F antenna (PIFA) are commonly studied . Among these structures, PIFA is frequently adopted due to its quarter‐wavelength resonant property …”

“…On the other hand, slots are always introduced into antenna design, not only to broaden its bandwidth but also to further decrease antenna size, especially in implantable antenna design . Because the requirement on antenna size is extremely critical, making the combination of PIFA and slotted ground an effective way to realize antenna miniaturization .…”

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.
