Frequency Reconfigurable Antenna

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.

Frequency Reconfigurable Antenna

AbstractIn this paper, we present a novel frequency reconfigurable antenna which could be easily operate in a single notched-band (WiMAX (3.3–3.6 GHz)) UWB frequency band, another single notched-band (WLAN (5–6 GHz)) UWB frequency band and the dual band-notched UWB frequency band (the stopband covers the WiMAX (3.3–3.6 GHz) and WLAN (5–6 GHz)). The reconfigurability is achieved by changing the states of PIN diodes. The simulated results are in agreement well with the measured results. And the measured patterns are slightly changed with antenna reconfiguration. The proposed antenna is a good candidate for various UWB applications.
