Abstract:   Compact antenna typically refers to small-size and low-profile antenna, which still maintains decent radiation efficiency, such as planar inverted-F antenna (PIFA), microstrip patch antenna, etc. This type of antenna has been widely used due to its advantage of compact size and low fabrication cost.

With the development of communication, antennas with unique radiation features are required for different scenarios. For example, beam steering is desired for 5G; while endfire radiation is for vehicle-to-vehicle communications. These requirements bring challenges to the design of the compact antenna. In order to realize the features, designers always have to compromise on size, robustness, or fabrication cost.

To alleviate this problem, we propose a new design method that applies coupled modes into compact antenna designs. In this defense, I will demonstrate how to realize beam steering, endfire radiation with vertical polarization, and circular polarization, respectively. All the proposed antennas remain compact, robust, and cost-efficient.
