The loading effect of the PIN diodes in the antenna is also characterized by a full wave analysis and transmission line theory and comparisons between the real and ideal switches are also studied. Per design goals, it is demonstrated that the reconfigurable slot antenna has the same radiation pattern at all frequencies. IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 53, NO. 2 ... Design of Reconfigurable Slot Antennas Dimitrios Peroulis, Member, IEEE, Kamal Sarabandi, Fellow, IEEE, and Linda P. B. Katehi, Fellow, IEEE Abstract—In this paper the design of a compact, efficient and electronically tunable antenna is presented. A single-fed resonant slot loaded with a series of PIN diode switches constitute the fun- Reconfigurable Microstrip Patch Antenna using ... - IOSR Journals so that there is no coupling between these two polarizations. The switching speed of the PIN diodes is slower than the MEMS-based switches. Nanbo Jin designed the patch antenna [2] with switchable slot (PASS).This concept is implemented to design a novel reconfigurable antenna with both frequency and polarization diversities.
Reconfigurable antenna used to modify radiation pattern, polarization, or even the operating frequency to deal with the varying in the system parameters. So there are more than one goal for using the reconfigurable antenna. The reconfigurable antennas that have an ability to radiate...
Pin diode in reconfigurable antennas - edaboard.com Aug 17, 2018 · Hello I am working on reconfigurable antennas.I have simulated one design with switching element as pin diode. It is easy to switch the pin diode during designing of antenna. How can we switch the pin diode after fabrication of antenna???Do we need any extra supply for that. If we add some supply to change biasing of pin diode,it will lead to a concept of multiple feeds to antenna. An Electrically Small CPW Fed Frequency Reconfigurable … varactor diodes or PIN diodes as tunable components. Various methods have been introduced to achieve the recongurability while maintaining the compactness of the antenna. In [1], a PIN diode is used to recongure the dual band patch antenna (2.4 GHz and 3.5 GHz) to a single band (2.4 GHz) but overall dimensions of the antenna are 50 52 mm 2.

Vijay shanker et al Frequency Reconfigurable Microstrip Patch Antenna for Wireless Applications using P-i-N diode 927| International Journal of Current Engineering and Technology, Vol.6, No.3 (June 2016) Fig.1 Proposed Design of Antenna 3. Design of Frequency- and Pattern-Reconfigurable Wideband ... A wideband slot antenna with frequency- and pattern-reconfigurable characteristics for TD-LTE (3.4–3.8 GHz) and C-band (3.7–4.2 GHz) applications is proposed. The antenna consists of two symmetric slots that are fed by a fork-shaped microstrip line. Two PIN diodes are loaded in the slots to produce two different frequency bands.
Design and Analysis of a Frequency Reconfigurable Microstrip ... the other is designed using PIN diodes to enable switching between two different frequency bands. Silicon made optical switches have been used by some researchers to construct frequency reconfigurable antennas [24]. Some compound reconfigurable antennas using PIN diodes [25] and optical switches [26] have also been reported in the past. Investigations on Reconfigurable Dual Frequency Microstrip ... bothering about the antenna dimensions. Even though the PIN diode controlled reconfigurable antenna scheme described in the earlier section permits this, a n_r9,re_ flexible frequency tuning scheme can beaccomplished by‘ replacing the PIN diodes with Varactor diodes. Here Varactors are integrated with the extended slot ann of the dual frequency 3.1 Introduction - INFLIBNET
