Abstract
In this article we presented a creative design of the frequency reconfigurable micro strip patch antenna that is used for WLAN applications. Use PIN diode in the designed Uslot micro strip patch antenna and acting as a switch. The PIN diode was mounted on U-slot and when a particular frequency band is worked. The suggested work on the simulation is performed in HFSS. The simulation test shows strong effects on the reconfigurable frequency of the WLAN / WiMaX / ISM program.
Highlights
Through the development in networking technology, interest in reconfigurable antennas is increasing, especially for their applications in specific wireless communication systems
By changing the switching mode of two PIN diodes from ON-ON to OFF-OFF; this antenna can be adjusted to switch between two different mobile communication systems, respectively 3 G and 4G [2]
This paper introduces a new concept of frequencyreconfigurable antenna, using an aperture-coupled technique as feeding technique and stacked patch technology
Summary
Through the development in networking technology, interest in reconfigurable antennas is increasing, especially for their applications in specific wireless communication systems. Find a compact triple band in this paper 2.7 GHz, 3.2 GHz, and 5.3 GHz lightweight micro strip patch antenna with two U-shaped slots and a small ground plane. It was designed for potential use of WiMAX technology [1, 15]. The suggested antenna consists of a double slot for frequency reconfigurability, with six RF PIN diodes positioned at separate positions on the ground plane. The planned antenna consists of a double slot with six RF PIN diodes for the frequency reconfigurability located at different positions on the ground plane [11]. The organization of paper is first part is introduction, second section is conventional antenna, third section is modified uslot antenna, fourth section is proposed antenna, fifth section is result and discussion and sixth section is conclusion
