A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ... Frequency and pattern reconfigurable Yagi patch antenna ... By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Pattern and Frequency Reconfigurable Annular Slot Antenna ...
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 the board. The central frequency is 5.8 GHz and, by reconfiguring the matching circuit ...
In radio and telecommunications a dipole antenna or doublet [1] is the simplest and most widely used class of antenna. [2] [3] The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary … Radioengineering - April 2016, Volume 25, Number 1 [DOI: 10… The antenna structure is consist of a square radiation patch with an E-shaped slot, a modified ground plane with an inverted T-shaped strip that act as a parasitic stub and two parallel slots and a protruded strip which is connected to the … Microsoft Word - str_0680-0686 Abstract. This paper presents a reconfigurable loop nents such as PIN diodes [5] on the radiating structure of antenna with monopole-fed using embedded RF PIN based the antenna. switches and shorted parasitic elements for GPS applica- … untitled A pattern/frequency reconfigurable antenna is investigated in [2]. The authors used an L-shaped slot, PIN diodes, lumped capacitors and bias networks to obtain the required pattern/frequency tuning.

Frequency and pattern reconfigurable Yagi patch antenna ... Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Three of them operate at the higher frequency and two of them at the lower one. The main beams of these models point to different directions in the E‐plane. DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The mean length of the slot circumference is approximately 3 λs/2 at the frequency of 5.8 GHz Frequency-Reconfigurable Stacked Patch Microstrip Antenna ... elements of the antenna, thus resulting in a beam-reconfigurable antenna that can switch the radiation pattern to a different direction. This study focuses on a frequency-reconfigurable antenna that is designed into a multilayer structure (stacked patch) with considerably higher gain. Moreover, a new coupling method is
By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested.
