High Gain Dual Polarized Antenna using a Narrow Pulse Model in Minkowski Fractal Patch

摘要

High Gain Dual Polarized Antenna using narrow pulse model in Minkowski fractal Patch (MFP) is presented. This design consists of dual fed by two transmission line feed connectors placed onto the lower substrate as the feeding system, square patch antenna with a dimension of 60 mm × 60 mm, and dual-polarized MFP putting on the upper substrate. The simulated result shows that the antenna has a resonant frequency at 3.48 GHz, by the distance between MFP and square patch antenna is 10 mm. However, the radiation pattern between vertical and horizontal feed for standalone square patch antenna provides a similar gain of 2 dBi. The 2D Radiation patterns on the X-Z plane at phi-angle 45 and −45 degrees are dual-polarization. Moreover, the proposed antenna with MFS improves the gain of 5.6 dBi at 0 degrees on the X-Z plane at phi-angle 45 degrees and −45 degrees with HPBW of 71.7 degrees and 80.4 degrees, respectively.
