Analyzes a reflectionless antenna, achieving band suppression in ultra-wideband systems, suggesting effective design strategies.
In this letter, the analysis and design of a full‐band reflectionless printed log‐periodic dipole antenna (PLPDA) with dual absorptive notched bands is proposed. Resistive loading units (RLUs) are applied to the PLPDA, thereby achieving flexible notched bands through energy absorption rather than reflection. Resistors are loaded at the end of the feeding line to absorb nonradiated low frequency components, achieving full‐band reflectionless characteristic. The reflection coefficient is maintained below −10 dB from DC to 12 GHz, while the realized gain exhibits over 15 dB suppression at 2.45 and 5.8 GHz. Therefore, the proposed antenna is suitable for ultra‐wideband (UWB) systems requiring suppression of low frequency and targeted band interference.
