“…Typical value for R b is in order of hundreds kΩ to 1 MΩ, which is more than 1000 times of the characteristic impedance of the stubs. This configuration also allows the tuning voltage of various stub groups to be controlled independently, which enabled the design of a polarization-and frequency-reconfigurable antenna in [11].…”

“…Employing varactors, various techniques have been proposed in the literature such as loaded with shorting posts [3]- [6], slotted patch [7], [8] or near-field resonant parasitic monopole [9]. Recently, an effective and simple technique involving varactors with loading stubs has been proposed to design reconfigurable antennas [10], [11]. More specifically, in [10], periodic rectangular stubs are loaded at the open aperture of a half-mode substrate-integrated waveguide (HMSIW) cavity to vary the resonance frequency of the structure.…”

A family of reconfigurable antennas based on stubloaded substrate-integrated circuits, including a microstrip patch, a substrate-integrated waveguide (SIW) cavity and their variations is presented. The paper summarizes the reconfiguration concept proposed in recent papers and extend its applicability to further substrate-integrated geometries. In addition, the analysis, optimization and results of various reconfigurable antennas are revised with further discussions. The results demonstrate that the stub-loaded configuration provides a simple and effective solution to design reconfigurable antennas, especially in terms of convenient bias network and quasi-analytical the optimization of the desired frequency tuning-range.Index Terms-Reconfigurable antenna, periodic structure, substrate-integrate waveguide (SIW), microstrip patch, stubloaded.

“…To achieve this performance, many frequency reconfigurable antennas [1,2,3,4,5,6,7,8] and reconfigurable frequency selective surfaces [9,10] with wide tuning ratio were published. They can use switching components such as PIN diodes, varactor diodes, and microelectromechanical systems (MEMS) to provide multi-band operation more easily.…”

A frequency reconfigurable antenna array is presented. The array consists of eight arms with two different feed networks. By controlling PIN diode switches, high frequency array with four dipole elements and low frequency array with two dipole elements can be obtained, respectively. Resonant frequencies within the ranges of 1.0-2.5 GHz (Case I) and 2.5-6.0 GHz (Case II) can be achieved, which translates into an overall tuning ratio of 6:1 (1.0-6.0 GHz) for the antenna array. The proposed antenna array is simulated, fabricated, and tested with good agreement between measurements and simulations.

“…On the other hand, it has also been confirmed that lower gain TX-RX systems will be sufficient for shorter communication distances such as those associated with D2D applications [6]. More importantly, CP antennas are preferred for D2D application since they avoid any polarization mismatch problems in complex wireless channels [7]- [11].…”

-An omni-directional circularly polarized (OCP) antenna operating at 28GHz is reported and has been found to be a promising candidate for Device-to-Device (D2D) communications in the next generation (5G) wireless systems. The OCP radiation is realized by systematically integrating electric and magnetic dipole elements into a compact disc-shaped configuration (9.23 mm 3 = 0.0076 λ at 28 GHz) in such a manner that they are oriented in parallel and radiate with the proper phase difference. The entire antenna structure was printed on a single piece of dielectric substrate using standard PCB manufacturing technologies and, hence, is amenable to mass production. A prototype OCP was fabricated on Rogers TM 5880 substrate and was tested. The measured results are in good agreement with their simulated values and confirm the reported design concepts. Good OCP radiation patterns were produced with a measured peak realized RHCP gain of 2.2 dBic. The measured OCP overlapped impedance & AR bandwidth was 2.2 GHz, from 26.5 to 28.7 GHz, an 8.0% fractional bandwidth, which completely covers the 27.5 to 28.35 GHz band proposed for 5G cellular systems.
