摘要：
This paper presents a compact pattern reconfigurable antenna for sub-6 GHz (4.8 GHz-5 GHz) applications. The proposed antenna consists of a quarter-wavelength radiator with two circular slot-loaded oval-shaped patches on both sides of the radiator. The antenna's ground plane is loaded with an inverted L-shaped structure. Two PIN diodes are used to switch the direction of radiation. Good agreement between simulated and measured results is obtained. The -10 dB impedance bandwidth of the proposed design is 370 MHz. The peak gain is 5.5dBi, and efficiency is 82 % in different diode states. The proposed antenna is then analyzed with the Nordic nRF9160 DK board to check the design reliability.
