“…The designs of RF MEMS switches depend on their usage as series or shunt, movement could be lateral or vertical, it could have metal-to-metal connection or capacitive connection and actuation could be electrostatic, magnetostatic, piezoelectric or thermal [8]. In [9] a fixed-fixed metal membrane RF MEMS series switch is proposed for integration with a reconfigurable antenna.…”

In this paper a low profile frequency reconfigurable antenna is proposed that can conform to the host surface. The proposed design is a pixelated antenna structure with a grid of small metallic patches with RF switches for re-configurability. The prototype of the proposed design is designed on an FR4 substrate with the relative dielectric constant of 4.4 and thickness of 1.6 mm. This antenna is capable of resonating in three different frequencies. The prototype resonates at 10 GHz with return loss of − 12.47 dB and gain of 4.35 dB, 3.9 GHz with return loss of − 19.95 dB and gain of 3.52 dB and 2.6 GHz with a return loss of − 14.22 dB and gain of 4.26 dB. The simulated result shows that the gain of the pixel antenna on FR4 substrate ~ 4 dB comparable to gain attained by pixel antenna on substrates with low tangent loss and low dielectric constant. It is observed that the measured results are in good agreement with the simulated result.

“…Compared to the positive-intrinsic-negative (PIN) diode [5,6], micro-electro-mechanical systems (MEMS) [7,8], and gallium arsenide (GaAs) psuedomorphic high electron mobility transistor (pHEMT) [9,10], Silicon-oninsulator (SOI) CMOS process shares the important features of being fast, reliable, and highly integratable, and thus, becomes a preferred choice for switch applications [11,12,13,14]. The low break-down voltage and conductive substrate limit the standard bulk CMOS for RF switch applications [15,16,17].…”

This letter describes a single-pole six-throw (SP6T) antenna switch in a 180 nm silicon-on-insulator (SOI) CMOS technology for receive diversity and LTE transmit/receive applications. Using a new diode biasing method, the conventional biasing resistor and supply voltage are removed at the body of the stacked-FET switch, a diode is used to connect the body and gate for body bias instead. The biasing diode turns off and on and functions as a high and small resistor for the on and off state. The proposed design helps to achieve low loss and high linearity. The measured insertion loss (IL) at 0.9 and 1.9 GHz are roughly 0.29 and 0.46 dB, respectively. The switch shows a second harmonic of −86 and −83 dBc, and third harmonic power of −94 and −87 dBc with a +26 dBm input power at 0.9 and 1.9 GHz, respectively.
