摘要: This paper quantifies the gain and matching bandwidth variations of a planar inverted-F antenna (PIFA) for several dielectric substrates. The performance PIFA is assessed in two configurations. First, studied with different substrates radiating patch fixed dimensions 4.92 cm x 2.13 cm. effects constant perfect lossy on resonant frequency, are investigated. A drop 2 dB per decade observed. In second evaluation, physical element adjusted to achieve resonance at 1.14 GHz. reduces 1.5 decade.
