贴片天线和B类功率放大器集成在一起，通过抑制谐波来缩小尺寸和提高功率增加效率(PAE)。在贴片上蚀刻有谐波抑制狭缝，从而既支持线偏振又支持圆偏振。解释了缝隙的机制，并对这两个组件进行了表征和性能验证。测量结果表明，谐波抑制使天线的PAE提高了5%，并且天线的辐射方向图不受所有支持极化的谐波抑制缝隙的干扰。
A patch antenna and class B power amplifier are integrated for size reduction and high power added efficiency (PAE) through harmonic suppression. Harmonic suppressing slits are etched on the patch such that both linear and circular polarizations are supported. The mechanism of the slits is explained, and both components are characterized and examined for performance validation. Measured results show that the harmonic suppression leads to up to 5% improvement in PAE and that the antenna’s radiation pattern is not disturbed by the added harmonic suppressing slits for all supported polarizations.
