Reconfigurable Microwave Semiconductor Plasma Antenna
show that the proposed design can be used to design Multi Band Reconfigurable Antennas,with proper slot loading and proper parasitic patch loading, by making use of coupling among the Microstrip patch, Multiple bands can be obtained. Moreover the proposed Antenna has a wide tunable range. Improvements in the design canbe done by inserting true DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... For a non-reconfigurable design, these may be hard-wired slotline short circuits, but in the reconfigurable design, they are implemented with pin diodes. The short in the slot results in a reformation of the electric field distribution along the slot leading to a shift of the null in the short direction.

Ideally, reconfigurable antennas should be able to alter their operating frequencies, impedance bandwidths, polarizations, and radiation patterns independently to accommodate changing operating requirements. However, the development of these antennas poses significant challenges to both antenna and system designers.
Katehi's expertise is in circuit design and her research focuses on antennas. [16] [17] [20] She currently holds 19 patents. [20] [21] [22] Through her academic roles she has been a mentor to over 70 postdoctoral fellows. [22] Radioengineering - September 2018, Volume 27, Number 3 [DOI: 10… Therefore, a special type of the double ridge waveguides is introduced here to feed the center line longi¬tudinal slot antennas.
"In the past several decades, a number of microwave imaging techniques have been developed for detecting embedded objects (targets) in a homogeneous media. New applications such as nondestructive testing of layered composite structures …
Design of reconfigurable slot antennas - IEEE Journals ... Design of reconfigurable slot antennas 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 fundamental structure of the antenna.
