Abstract
A switchable microstrip patch antenna for multi-frequency operation is presented. The antenna is fed by coplanar waveguide via capacitive coupling slot. The antenna allows an easy reconfigurability of the frequency band of operation by incorporating switches in the coupling slot. The resonant frequency of the antenna can be adjusted by setting the switches on or off. The antenna is capable of switching between 1.6, 1.8, 2.0 and 2.4 GHz. Measurements show that the realized gain is 5.2, 4.4 and 4.9 dB for the 1.6, 2.0 and 2.4 GHz frequency bands respectively. Both simulation and measurement results indicate that the proposed antennas demonstrate very good impedance matching, stable radiation patterns and reasonable gain at all frequency bands.
