PIN diodes or varactor) to achieve frequency agility. In [14-15], a simple way to achieve the antenna agility is by selectively switching in or out some parts of antenna structure. In this article, a novel frequency reconfigurable slot antenna is presented. The antenna consists of a microstrip patch and a slot etched out in the ground plane. Pattern and Frequency Reconfigurable Annular Slot Antenna ... Return loss and radiation pattern measurements and simulations are presented, which are in very good agreement. Index Terms—Annular slot antenna (ASA), frequency reconfigurability, pin diode, reconfigurable antenna, reconfigurable radiation pattern, slot antenna. I. Frequency-Reconfigurable Stacked Patch Microstrip Antenna ... slots, coupling, frequency-reconfigurable antenna, PIN diode and stacked patch I. INTRODUCTION Reconfigurable Microstrip Antennas (RMAs) are a current technology that has been adequately applied in modern wireless systems or radar applications. RMA basically comes from the conventional microstrip antenna. But, the antenna

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.

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.

require smart and reconfigurable antennas with easily controlled radiation patterns. The Annular Slot Antenna (ASA) proposed in this paper operates at 5.8 GHz and the use of pin diodes along the slot circumference allows the radiation pattern to be directed in a number of different directions while the operation frequency remains constant. It ...
