摘要：

A compact planar inverted-F antenna (PIFA) consisted of two meandered strips with bandwidth enhancement technique is proposed for implantable biotelemetry in MICS band. The antenna occupies a volume of only 791 mm(3) (2205 mm by 18.5 mm by 1.9mm) operating at 402 MHz PIFA with two meandered strips can excite dual-resonate frequencies that control the resonant frequencies at 380 and 440 MHz, respectively, to obtain the broad bandwidth of 120 MHz (353 473 MHz) at a return loss of 10 dB. To verify the performance of implantable antenna the test tissue is adopted as implanting environment by grinding the park of front-leg. Furthermore, the property of this antenna can remain consistency against the varying and complex human tissue. Thus, this letter provides a miniature, broadband implantable PIFA for biotelemetry of medical devices. (C) 2009 Wiley Periodicals, Inc.
