摘要
在不同的衬底下，对固定尺寸的平面倒f天线(PIFA)进行了评估，该天线的辐射单元高度为4.92 cm x 2.13 cm，高于地平面4.4 mm。研究了谐振频率、带宽和增益与完美基片和有损基片相对介电常数的关系。结果表明，归一化谐振频率(δ taf/f)呈对数递减，增益以每10年2 dB的斜率线性递减。
A Study of substrate permittivity effects on the gain of planar inverted-F antennas
A planar inverted-F antenna (PIFA) of fixed dimensions, with a 4.92 cm x 2.13 cm radiating element 4.4 mm high above the ground plane is evaluated with different substrates. The resonance frequency, the bandwidth and the gain are studied in relation to the relative dielectric constant of the perfect and lossy substrates. The results reveal that the normalized resonance frequency (Deltaf/f) decreases logarithmically and the gain drops linearly with a slope of 2 dB per decade.
