Chapter 4. Antennas and Arrays for MmWave Applications

4.1 Introduction

The extremely short wavelengths of mmWave signals (e.g., 10.7 mm at 28 GHz, 5 mm at 60 GHz, and 789 μm at 380 GHz) offer enormous potential for mmWave antenna arrays that are adaptive, high gain, and inexpensive to fabricate and integrate in mass-produced consumer electronic products. There are both cost and performance advantages that result from extremely integrated and physically small antennas. From a cost perspective, mmWave antennas may be directly integrated with other portions of a transceiver and may be fabricated with either packaging or integrated circuit (IC) production technology. This is a stark departure from all existing wireless systems to date, which rely ...
