This paper introduces a compact millimeter-wave tunable filtenna with defected ground-plane structure (DGS) resonators for future fifth generation (5G) applications. An approach of adding the lumped and tunable elements within the DGS resonating structure is introduced. The designed filtenna has achieved a good reflection coefficient |S 11 | lower than −25 dB with a realized gain higher than 9 dB at any of the tuned frequency bands. A good agreement is achieved between the measurements and the simulated results those produced from both the finite difference time domain method (FDTD) Matlab coded and the CST-MWS simulation program. Furthermore, a circular array consists of 16 antenna elements is designed to be integrated into 5G router device. Different scenarios have been considered to show the array performance capability to maximize the array directionality in certain directions at certain frequency and in other directions with another frequency band. Finally, the scan pattern with the coverage efficiency are presented to illustrate the capability of the designed array as a key piece of future 5G routers.

“…In this direction, the demand for new antennas with a capability to work in the newly proposed architectures has increased, and reconfigurable antennas represent a potential candidate to fulfill the 5G requirements [8][9][10][11]. Furthermore, the CR applications require using two different antennas: a broadband antenna for spectrum sensing and a tunable narrowband antenna after selecting the operating channel [12].…”

This work reports the concept and development of two mechanically frequency-tunable horn filtennas for microwave and millimeter-waves. Our design approach relies on the integration of a horn antenna with a mechanically tunable filter based on dual-post resonators. The proposed filtennas have been manufactured and experimentally characterized, by means of reflection coefficient, radiation pattern, and gain. Measurements demonstrate that both filtennas have a tuning ratio of approximately 1.37 with continuous adjustment. The first prototype operates from 2.56 to 3.50 GHz, whereas in the second one the bandwidth is from 17.4 to 24.0 GHz. In addition, the higher-frequency filtenna has been implemented in a 5.0-meter-reach indoor environment, using a 16-QAM signal at 24 GHz. The best configuration in terms of performance resulted in a root mean square error vector magnitude (EVMRMS) and antenna radiation efficiency of 3.69% and 97.0%, respectively.

“…Reconfigurability, that is continuous optical control of the electrical power or phased-shift level of the microwave signal transmitted through devices, has become a crucial feature in modern, agile, microwave and millimeter wave (MMW) systems for emerging wireless communications, sensing and imaging. 1,2 Among various existing building blocks, optically reconfigurable MMW amplitude and phase-shift switches are key devises for beam steering in RADAR systems and reconfigurable antennas for emerging 5 G wireless communications network 3,4 . An optically controlled switch is a device whose electrical state can be tuned from insulating (Off state) to conductive (On state) by means of optical stimuli 5–8 .…”

“…The idea of using light to control or even introduce signals directly into microwaves devices 4,10,11 has drawn great interest in the microwave community driven by the need for dynamic control, fast response, immunity to electromagnetic interference, and good isolation between the controlling and controlled devices. The optical solution promises better performances compared to its classical analogue that utilizes electrical or microelectromechanical system which are prone to signal distortion and unwanted electromagnetic interferences 1 .…”

Microwave photonics uses light to carry and process microwave signals over a photonic link. However, light can instead be used as a stimulus to microwave devices that directly control microwave signals. Such optically controlled amplitude and phase-shift switches are investigated for use in reconfigurable microwave systems, but they suffer from large footprint, high optical power level required for switching, lack of scalability and complex integration requirements, restricting their implementation in practical microwave systems. Here, we report Monolithic Optically Reconfigurable Integrated Microwave Switches (MORIMSs) built on a CMOS compatible silicon photonic chip that addresses all of the stringent requirements. Our scalable micrometer-scale switches provide higher switching efficiency and require optical power orders of magnitude lower than the state-of-the-art. Also, it opens a new research direction on silicon photonic platforms integrating microwave circuitry. This work has important implications in reconfigurable microwave and millimeter wave devices for future communication networks.
