Abstract

In recent years reconfigurable antennas have attracted a lot of attention in modern wireless communication systems. In satellite communication and ECM system, there has always been a continuous demand for smaller size, lighter weight antenna system that has properties to accomplish selectivity in frequency, bandwidth, polarization and gain. A frequency reconfigurable antenna is proposed for wireless communication. We can achieve Frequency reconfiguration by modifying physical or electrical dimensions of the antenna using RF-switches, impedance loading or tunable material. The design and simulation of the proposed antennas are done using ANSYS high-frequency structure simulator (HFSS) version-19. The proposed antenna is taken as a triangular shape whose length and width are 50mm and 25mm respectively. Here reconfigurability is achieved by RF switches placed in the radiator. The antenna analysis is done by taking different conditions of the switch. Total four switching condition is simulated and for each case, distinctive resonating frequencies are accomplished with acceptable reflection coefficient. The frequency bands of the antenna are varied from 2.12 GHz to 5.27 GHz. This antenna covers S-band and C band. After simulating the design the gain and efficiency of the antenna are verified successfully. Antenna fabrication and measurement of different parameters will be done in future. A comparison of the measured result will be analyzed with some existing antenna outcomes.
