N2 - A reflectionless antenna with compact size and wideband absorption is proposed. A reflectionless slot antenna consists of a frame ground, a microstrip feed line, a bandstop filter, and a resistor. The bandstop filter is composed of a capacitor and an inductor, placed at the end of the microstrip feed line with a resistor. The in-band input energy is radiated by the antenna, while the out-of-band energy is dissipated through the resistor via the bandstop filter, resulting in a wideband reflectionless characteristic. The fabricated reflectionless slot antenna exhibits wide reflectionless bands ranging from DC to 9.72 GHz. Within the operating band, the bandstop filter with a resistor has almost no effect on the gain of the slot antenna. The wideband reflectionless characteristics and compact dimensions make the antenna potentially useful for mobile communications.
