INTRODUCTION Recent years have seen significant technical advances in state-of-the-art wireless networking technologies, with a clear continuing focus in multiband antenna science. Higher spectral performance and the need to accommodate large data speeds, multimedia-based compact-sized networks present significant technological challenges in traditional antennas. In this respect, the multiband antenna proved to be an outstanding choice due to its capacity to incorporate more than one connectivity protocol into a single compact device, in addition to its low cost and fast data rate functionality. Nevertheless, antenna architecture development also needs to face the technological challenges presented by that frequency ranges, bandwidth fragmentation, interference, and so on. The antenna may be reconfigured by adjusting its frequency, polarization or radiation characteristics by utilizing some form of switching system, such as pin diodes, RF MEMS, Varactor diodes, etc. Microstrip antennas are widely used to provide reconfigurability due to their advantages of low profile, light weight, low manufacturing cost, and ease of RF device integration. Frequency reconfigurability can be accomplished by changing the shape of the radiant element by altering the resonant frequency. Switches are used to achieve selectivity of frequencies by manipulating switch status; switches can be pin diode, varactor diode or RF MEMS. In [3] this paper presents a new, reconfigurable, single-feed, dual-frequency, dual-polarized function of a square microstripe antenna packed with hexagonal slots. The size reduction up to 61% to 26%and bandwidth 3.3% and 4.27%. In [4] this study, a lightweight WLAN dual-band frequency reconfigurable antenna is proposed.

Dr.RAJU Yanamshetti, Professor,DepartmentofElectronicsand CommunicationEngineering,PDACE,Kalaburgi, (Karnataka), INDIA, Emailid:rayan5@rediffmail.com Miniaturization and dual-band activity is carried out in the built antenna through the addition of hexagonal slots and frequency reconfiguration is accomplished through two PIN diode switches assisted by their bias circuits. In [5] this paper discusses a reconfigurable microstrip slot antenna configuration and analysis utilizing RF PIN diodes as S and C-band switching devices. Here, the reconfigurable pattern and frequency of the microstrip antenna is built by adjusting the duration of the ground plane slot by six MPP4203 PIN diodes. In [6] this paper suggests a parallel dual-band, Shaped microstrip patch antenna reconfigurable bandwidth. The antenna would automatically turn all frequency bands at the same time without the requirement for an additional coordinating network. If the PIN diodes are 'OFF' (reverse bias) which are reconfigured to 3.1 GHz and 7.2 GHz while the PIN diodes are turned 'ON' (forward bias) the suggested antenna resonates at 3.5 GHz and 8.1 GHz. In [7], this paper presents the concept of a frequency reconfigurable E-shaped patch antenna utilizing particle swarm optimization. Ideal switches are used to show evidence of the principle of reconfiguration of the frequency. A slotted patch antenna configuration which can be reconfigured with a new frequency is given here in [8]. The slots created on the aperture of the antenna are designed to orient by having their orientation, either clockwise or clockwise, a reference point. Such direction distributes the surface currents in a number of directions, resulting in a shift in their resonance strength. In [9] this paper describes a reconfigurable square slot antenna. The planned antenna consists of a square slot on one side of the substrate, and a micro strip feed on the otherIn this article, the PIN diode was used to illustrate the idea of an X-band frequency reconfigurable patch antenna. In order to understand the influence of the PIN diode on antenna parameters, a square slot has been added. In [11] this paper proposes a multiband frequency reconfigurable antenna for intelligent transport system (ITS) applications. The reconfigurability is based on a PIN-diode. Center frequencies are 1.38, 1.98, 2.89, 3.86, and 4.34 GHz in Diode "ON" mode, and 1.56, 2.16, 2.88, 3.91 and 4.45 GHz in "OFF" condition. The average bandwidth obtained is 18 percent. The proposed antenna's nominal gain is 2.7 dBi in "ON" state, and 3.95 dBi in diode "OFF" state. In[12] this letter suggests a lightweight frequency reconfigurable slot antenna for applications for LTE (2.3 GHz), AMT fixed range (4.5 GHz), and WLAN (5.8 GHz).In order to perform dual-band operation a U-shaped slot with short ends and an L-shaped slot with open ends are etched in the ground plane. By inserting two PIN diodes within the slots, three frequency bands can easily be reconfigured over a frequency ratio of 2.62:1.In [13] it proposes a simple and compact slot antenna with a very large tuning range.
