An Efficient Ladder Reflector Antenna for Interchip Communications

Abstract

A new compact 24-GHz ladder reflector antenna on chip has been developed using the standard 0.18-um six metal layers complementary metal-oxide-semiconductor (CMOS) process. The antenna consists of an active dipole and a ladder reflector array. The ladder reflector array successfully adjusts the radiation direction of the active dipole and effectively suppresses the active dipole interference to chip circuit. The measured results show that the ladder reflector antenna has a 6.25-dBdc gain at 24 GHz and a 6-dB 11 impedance bandwidth of 19.92-27.60 GHz. The design method presented in this letter is quite straightforward, and can be used to develop antenna on chip for the wireless interconnect for interchip communications.

Current trends and future perspective of designing on-chip antennas

“…Generally, OCAs are used for short range applications like intra-chip and inter-chip [17][18][19], short range radar [20,21], RFID tags [22,23], biomedical implantable devices [24,25], etc., where along with the efficient radiation characteristics, low power, compact system, capable in fast data communication is the prime concern. Moreover, the present and upcoming generation of the communication networks such as 5G and 6G demand more traffic handling capacity, reduced latency, and less energy consumption.…”
