Abstract This paper proposes a transmit/receive (T/R) nanoswitch in 130 nm CMOS technology for 2.4 GHz ISM band transceivers. It exhibits 1.03-dB insertion loss, 27.57-dB isolation and a power handling capacity (P1 dB) of 36.2-dBm. It dissipates only 6.87 μW power for 1.8/0 V control voltages and is capable of switching in 416.61 ps. Besides insertion loss and isolation of the nanoswitch is found to vary by 0.1 dB and 0.9 dB, respectively for a temperature change of 125°C. Only the transistor W/L optimization and resistive body floating technique is used for such lucrative performances. Besides absence of bulky inductors and capacitors in the schematic circuit help to attain the smallest chip area of 0.0071 mm2 which is the lowest ever reported in this frequency band. Therefore, simplicity and low chip area of the circuit trim down the cost of fabrication without compromising the performance issue.

Isolation Performance

A multi-input multi-output (MIMO) antenna with high isolation is proposed for 2.4 GHz ISM band (2.4–2.485 GHz) WBAN applications. The proposed MIMO antenna consists of two PIFA elements and utilizes an isolator composed of a shorted strip and two slits in the ground plane. Although the separation between the two PIFAs is minimized to 8 mm (0.06 λ∘), isolation performance is improved by virtue of an isolator. To analyze the antenna’s performance on a human body, the proposed antenna is placed on a human muscle-equivalent flat phantom and is investigated through simulations. The measured −10 dB reflection coefficient bandwidth of the antenna ranges from 2.11 GHz to 2.6 GHz, and the isolation is lower than −38 dB over the 2.4 GHz ISM band.
