Characteristic Mode Analysis of a Ka-Band CPW-Slot-Couple Fed Patch Antenna with Enhanced Bandwidth and Gain

A Ka-band CPW-Slot-Couple (CSC) fed microstrip antenna with enhanced bandwidth and gain is presented in this paper. To simplify the feed network, matching slots are designed at end of CPW. Consequently, patch a low profile, which has size 7.2 × 32.6 0.508 mm3. Characteristic mode analysis (CMA) applied to illustrate principle enhancement band form characteristic point view. slot based on inductive loading employed parasitic move resonant frequency CM3 CM2 for bandwidth, avoids introducing additional impedance networks. The measured results show that proposed monolayer 14.18% from 24.84 28.6 GHz peak 7.9 dBi. Due its attractive properties compact configuration, wide band, high gain, could be miniaturized millimeter-wave applications.
