A frequency reconfigurable slot antenna - INFONA This paper proposed a frequency reconfigurable CPW center-fed slot antenna. Four pin-diodes are utilized to switch the length of the slot. By tuning the different pairs of diodes on or off, three resonant frequency bands can be obtained. The simulated and measured results validate this concept. This antenna architecture is interesting for wireless applications because it is easily fabricated ... A Compact Flexible and Frequency Reconfigurable Antenna ... 656 M. U. HASSAN , F. ARSHAD, S. I. NAQVI, ET AL., A COMPACT FLEXIBLE AND FREQUENCY RECONFIGURABLE ANTENNA… Switching is achieved by four pin diodes along with the slotted structure that is created on the ground. Microstrip based frequency reconfigurable antenna is proposed in [14]. Using five pin diodes it achieves six switchable bands Reconfigurable Ground-Slotted Patch Antenna Using PIN ... 832 Seung-Bok Byun et al. ETRI Journal, Volume 29, Number 6, December 2007 ABSTRACT⎯This letter presents a reconfigurable ground- slotted patch antenna using a PIN diode connection in slots to achieve dual-frequency operation. Slots in the ground plane increase the electrical length and thereby reduce antenna size
By using two PIN diodes, the designed antenna is capable to operate in two modes. ... frequency reconflgurable slot-patch antenna [23].

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.

Pattern and Frequency Reconfigurable Annular Slot Antenna CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract—This paper presents the use of pin diodes to reconfigure the impedance match and modify the radiation pattern of an annular slot antenna (ASA). The planar antenna is fabricated on one side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the opposite side of A quad-polarization and frequency reconfigurable square Frequency diversity characteristic is achieved using a PIN diode in the U-slot and the polarization diversities among linear polarization (LP), right-hand circular polarization (RHCP), and left-hand circular polarization (LHCP) are obtained by switching three PIN diodes placed on the slot and truncating corners of square patch.
