“…With the recent advances in technology, these demands can now be met. This section provides the details of the so called PROMFA circuit concept, which consists of a matrix of analogue building blocks that can be dynamically reconfigured [12,13]. The idea of having flexible RF systems with reconfigurable circuit blocks is becoming more and more popular.…”

“…Here the analogue building blocks (PROMFA cells) are connected together, and to control the behaviour of each analogue cell a digital control logic is placed between them. Figure 12.3 illustrates the PROMFA subcell that includes a bidirectional amplifier stage and a bypass (pass-transistor switch) [13]. The array can therefore realize more complex functions, such as filters or oscillators.…”

“…The individual PROMFA cells can be configured in a number of ways, for example as an amplifier, power splitter, power combiner, router, and so on. [13]. The PROMFA system utilizes a twodimensional mesh network topology, which is also a common routing topology used by digital network routers.…”

In this letter, a simply accessed approach of 2D‐shaping liquid metal (LM) is presented. This approach allows a microwave device to take advantage of LM in both stretchability and removability. This approach is achieved based on the Young–Laplace theory of liquid surface tension, as well as the surface oxidization that LM possesses. An application example of this approach is demonstrated by a functional changeable microwave device. The proposed device operates in antenna mode when LM is not incorporated. Then, it can change to resonator mode after filling 2D‐shaped LM into fluidic channels. To our knowledge, it is the first device that is capable of changing its function using LM. The measured gain of the proposed microwave device is 7.1 dBi at 2.68 GHz when it operates in antenna mode. The measured insertion loss of the proposed microwave is 1.8 dB at 2.62 GHz when it operates in resonator mode.

This paper describes a multi-functional microwave device that can be reconfigured to behave either as a filter or an antenna. The device is based around a single resonant element, referred to as a building block element that is connected to 4 ports. The resonant element is a microstrip square patch working in the 2.45 GHz unlicensed Industrial Scientific and Medical (ISM) band used for IEEE 802.11 WiFi. The proposed building block is simple in its design and construction. The paper also presents devices composed of three building blocks, which can realize more complex filtering and antenna mode performance. In addition, PIN diodes have also been incorporated into the devices in order to facilitate electronic control. Measured results, pertaining to fabricated prototypes, show that filter and antenna operation can be achieved, in the same device at a frequency of around 2.45 GHz with acceptable insertion loss and efficiency. In the future, it is anticipated that this could lead to a new paradigm, namely a device that is analogous to a field programmable gate array (FPGA) operating in the microwave frequency regime.
