摘要

This communication focused on the design development of a low-loss, patch size enhancement and a wideband four-element monopole antenna for Ka-band and millimetre wave (mm-wave) communications. This study presents the 4-patch duplication antenna, which has frequency reconfigurability via two PIN diodes and frequency sensitivity via one varactor diode. The proposed technology provides an alternative to tediously built antenna arrays. A small Rogers RT Duroid 5880 (0.508 mm) makes the antenna low-loss. The affect of varactor biasing on tuning linearity, stability, and repeatability have been studied. Excellent impedance matching at 32.5 GHz is achieved with this patch-size enhancement approach. One-element antennas without slots have a peak gain of 6.79 dBi at 32.5 GHz, while slot antenna have 7.02 dBi. The improved four-element array antenna increases the gain to 8.32 dBi. Gain is further improved to 9.81 dBi with the digital modes of PIN diodes. The measured reflections ( \(\:{\text{S}}_{11})\) and radiation properties were found to be consistent with the simulations. The suggested antenna performs well between 26 GHz and 40 GHz, as evidenced by its − 10 dB bandwidth and results. The observed data showed that the proposed design is suitable for mm-wave and 5G sub-6 GHz frequency range 2 (FR2), and beyond applications.
