A high performance micromachined CPW fed aperture coupled compact patch antenna using a double-tuned impedance matching method
This paper presents the design and fabrication of a high-performance patch antenna for operation over the X-band (8 – 12 GHz) frequency region. A wide impedance bandwidth is obtained using a double-tuned impedance matching technique. The wideband antenna consists of a short-end CPW and the coupling aperture on an FR4 substrate, and a suspended patch. The triple resonance effect associated with the characteristics of the double-tuned aperture and the patch is used to achieve wideband performance. The effects of the design parameters of the CPW line, the aperture, air gap and the patch are studied. The patch was fabricated on a thin film LCP substrate. A laser micromachined polymer rim was used to create an air gap between the LCP substrate and the FR4 substrate. The measured results show a good agreement with that of the simulation work. The impedance bandwidth of the antenna is as large as 41% covering the X-band. The 3-dB gain bandwidth is 43% and the maximum gain is 8.5 dBi.
