In this paper, a novel broadband square slot antenna was promoted, which can realize dual circular polarization by embedding in the square slot two nearly mirror-symmetric L-shape strips. Also, we add a reflector on the backside of the antenna in order to reflect electromagnetic waves to achieve high gain. Moreover, stubs are supplemented to the L-shape strip to broaden the axial ratio (AR) bandwidth...
Research on miniaturization of HF antennas is one of the hot research areas. A novel miniaturized broadband HF antenna whose largest size is only 3.6m is presented in this paper. Simulated results demonstrate that the antenna is self-resonant and can be matched to a 50 Ω input feed line without external matching networks or loading in a wide band. The antenna has realized miniaturization while maintaining...
