Multi-State Reconfigurable Antenna for Wireless Communications
- 6 Downloads
A compact frequency and polarization reconfigurable antenna is presented. The antenna comprises of a truncated corner square patch along with two strip lines running parallel to it. The entire model is fabricated on single layer roger RO 4350 substrate. Pin diodes are used for switching frequency and polarization states. Two ports are used for switching polarization states. The antenna can achieve two frequency bands and four polarization states. The antenna model is fabricated and the measured results are compared with simulated results. The antenna achieves − 10 dB impedance bandwidth of 100 MHz for LP state and 50 MHz for CP state and also the antenna attains good cross-polarization isolation of > 15 dB in all states. The antenna gives a maximum measured gain of 5.48 dBi for linear polarization (LP) state and 4.82 dBi for circular polarization (CP) state.
