mmWave Double Cavity-Backed Slot Antenna featuring Electrically Small and Low-Profile

摘要

This paper describes a mmWave double cavity-backed slot antenna (CBSA) for mmWave frequencies. The proposed antenna achieves dual resonance at 28GHz and 38GHz. The finalized 1 × 4 antenna array features 5.64 dBi and 8.84 dBi gain at 28GHz and 38GHz, respectively.
