An Aperture-couple Stack Antenna with Minkoski-island-based Patch for Circular Polarization and Wide-band Applications
A stack-structure antenna with Minkoski-islandbased patch for circular polarization and wideband applications has been presented in this paper.The proposed antenna structure is stacked by two FR4 substrates.The bottom substrate is fed by single-feed line coupled with aperture; while the Minkoski-island-based patch is etched on the top substrate which is responsible for the excitation of the wideband response in dual-mode and radiating the circular polarization in orthogonal mode.The stacked form antenna presents the axial ratio(AR)with 3-dB bandwidth of 30MHz obtaining 1.2%of bandwidth percentage at 2.44 GHz and the wideband response with 10-dB bandwidth of 290MHz possessing 12%of bandwidth percentage particularly.The radiation patterns show the directional patterns at 2.34 GHz and 2.5 GHz resonance frequencies respectively.The peak power gains are 0.11 dBi and 0.2 dBi correspondingly.The polarization pattern at 2.44 GHz displays the right-hand circular polarization(RHCP)characteristics.It can be properly applied to the WLAN band.
