An efficient ladder reflector antenna for inter-chip communications

This paper presents a theoretical study of a new ladder reflector antenna with standard CMOS process. The antenna consists of an active dipole and a ladder reflector array. The ladder reflector array successfully changes the radiation direction of the active dipole and the ladder reflector antenna radiates majority energy to the outside of the chip. The measured results show that the ladder reflector antenna has a 6.25 dBdc gain at 24 GHz and a -6 dB Sll impedance bandwidth of 19.92-27.60 GHz. So it´s very suitable for the wireless interconnect for inter-chip communications.
