“…The stubs play the role of reflectors and/or directors due to each set of PIN diodes, allowing the beam to be focused in the desired direction. The model of PIN diode used here is the BAR64-03W E6327 by Infineon, which operates up to 6 GHz; its equivalent circuit model for OFF and ON states [24] are shown in Fig. 3.…”

Abstract-In this paper, a four switchable beam antenna dedicated to Wireless Sensor Network (WSN) nodes in the 2.4 ISM band (2.4-2.485 GHz) is presented. It consists of two fed monopoles and two loaded parasitic ones. The nature and value of the load are obtained using the Uzkov equations, allowing to determine current weighting coefficients in the case of two separately fed antennas, in order to maximize the gain and the directivity in a given direction. Reconfigurability is achieved using reflector and director elements activated by PIN diodes to reduce the back radiation and pointing in the desired direction. Thus, a first system is obtained which consists of two elements, one fed and the other loaded with an inductor, with a maximum gain of 5.2 dBi in simulation and 4.7 dBi measured at 2.4 GHz in azimuthal directions of 90 • and 270 • . Then, the system is compared with another, composed of two antennas fed separately. Finally, the same methodology is applied to an array of four antennas, in which two antennas are fed, and two are loaded. This last structure is capable of steering its radiation pattern in the azimuth plane, covering a 360 • angle with four beams (0 • , 90 • , 180 • and 270 • ). The total gain achieved is 4 dBi for each beam in the azimuth plane.

“…It is believed that this is due to loss tangent of substrate, fabrication tolerances and biasing network. It can also be due to the difference between the behavior of the actual PIN diode and the modeled PIN diode which leads to frequency shift [39]. In addition, the return loss of the measured band notches decreases compared to the simulated one which is mainly due to the current limit of the PIN diode at the ON state, where the maximum supplied voltage is 1.1 Volt [40].…”

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.

“…[7][8][9] Due to compact size, light weight and low cost, planar microstrip fed antennas are desirable for commercial wireless UWB applications. 10 Various types of band notched UWB antennas have been designed with different methods to achieve reconfigurability like using PIN diodes, 11,12 radiofrequency (RF) microelectro mechanical switches (MEMS), 13,14 and optical switches. 15 In, 11 circular slot antenna is presented for reconfigurable dual band UWB applications in which three PIN diodes are used to switch between various operating modes of antenna which is greater than optimal number of PIN diodes needed to switch between various dual band rejecting operating modes.…”

A compact ultra-wideband (UWB) reconfigurable microstrip fed monopole antenna having size of 0.22 λ 0 × 0.28 λ 0 × 0.005 λ 0 with switchable frequency bands is presented. Triple band notched characteristics are achieved by inserting two stubs at top of radiator and one slot in between the radiator and microstrip feed line. Proposed antenna achieves reconfigurability with three PIN diodes at strategic positions to obtain eight different operational modes. In one of the operational modes, antenna operates in the entire UWB (3-14 GHz) with fractional bandwidth of 127.5%. Two stubs are used to notch two frequency bands worldwide interoperability for microwave access (3.3-3.6 GHz/WiMAX) and C-band (3.7-4.2 GHz). T-shaped slot is also inserted to notch wireless local area network (5.725-5.825 GHz/WLAN) frequency band. Proper biasing of PIN diodes is done by using suitable chip inductors and capacitors. Proposed antenna exhibits stable radiation patterns with average gain of around 3 dBi. Simulation and measurement results are in good agreement. Proposed antenna is suitable for on-demand band rejection of parasitic bands coexisting in UWB. K E Y W O R D S frequency reconfigurable, monopole antenna, PIN diode, ultra wideband
