“…The challenges in this approach are the difficulty of maintaining good antenna performance over a very wide frequency range and the complex geometry of multi-band antennas. Also, a very high capability of out-of-band noise rejection is required for the tunable filters [9]. An alternative approach is to integrate the tuning components inside the antenna to form a tunable multiband antenna.…”

Abstract-This invited paper considers a key next step in the design of radio architectures aimed at supporting low energy consumption in 5G heterogeneous radio access networks. Stateof-the-art mobile radios usually require one RF transceiver per standard, each working separately at any given time. Software defined radios, while spanning a wide range of standards and frequency bands, also work separately at any specific time. In 5G radio access networks, where continuous, multiband connectivity is envisaged, this conventional radio architecture results in high network power consumption. In this paper, we propose the novel concept of a concurrent multiband frequency-agile radio (CM-FARAD) architecture, which simultaneously supports multiple standards and frequency bands using a single, tunable transceiver. We discuss the subsystem radio design approaches for enabling the CM-FARAD architecture, including antennas, power amplifiers, low noise amplifiers and analogue to digital converters. A working prototype of a dual-band CM-FARAD testbed is also presented together with measured salient performance characteristics.

“…Recently, reconfigurability applications are used in modern technology [9]. Thus reconfigurable antennas have gained tremendous research interest in many applications such as cellular radio system, radar applications [10], aircraft, mobile, satellite communications, Unmanned Airborne Vehicle (UAV) radar, smart weapon protection and microwave imaging that requires flexibility to support many standards (e.g., UMTS, Bluetooth, WiFi, WiMAX, DSRC), mitigate strong interference signals and cope with the changing environmental condition [11,12].…”

Abstract-This study presents a novel technique for designing an ultra-wideband (UWB) filteringantenna with dual sharp band notches. This design is composed of a modified monopole antenna integrated with resonant structures. The monopole antenna is modified using microstrip transition between the feedline and the patch. In addition, block with a triangle-shaped slot is loaded on each side of the ordinary circular patch to produce wide bandwidth with better return loss and higher frequency skirt selectivity. The resonant structures are constructed using two double split ring resonators (DSRR) loaded above the ground plane of the antenna to produce dual band notches and filter out WiMAX (3.3-3.7 GHz) and HiperLAN2 (5.4-5.7 GHz) frequencies. The band notch position is controlled by varying the length of the DSRR. The reconfigurability feature is achieved by using two PIN diode switches employed in the two DSRR. The measured results show that the proposed filtering-antenna provides wide impedance bandwidth from 2.58 to 15.5 GHz with controllable dual sharp band notches for WiMAX and HiperLAN, peak realized gain of 4.96 dB and omnidirectional radiation pattern.

“…In [15], Slot-ring patch antenna loaded with multi MEMS has been proposed and designed giving three different approaches (switchable antenna with RF-MEMS switches, wideband or multiband antenna integration with tunable filters, and array architectures). In [16], the CPW technology is combined with RF-MEMS cantilevers for the design of the reconfigurable UWB antenna.…”

“…The main problem with these papers is the hybrid structures (heterogeneous integration); only a few papers, such [15], have used the monolithic structure.…”
