Abstract
A compact ultra-wideband (UWB) reconfigurable microstrip fed monopole antenna having size of 0.22 λ0 × 0.28 λ0 × 0.005 λ0 with switchable frequency bands is presented. Triple band notched characteristics are achieved by inserting two stubs at top of radiator and one slot in between the radiator and microstrip feed line. Proposed antenna achieves reconfigurability with three PIN diodes at strategic positions to obtain eight different operational modes. In one of the operational modes, antenna operates in the entire UWB (3-14 GHz) with fractional bandwidth of 127.5%. Two stubs are used to notch two frequency bands worldwide interoperability for microwave access (3.3-3.6 GHz/WiMAX) and C-band (3.7-4.2 GHz). T-shaped slot is also inserted to notch wireless local area network (5.725-5.825 GHz/WLAN) frequency band. Proper biasing of PIN diodes is done by using suitable chip inductors and capacitors. Proposed antenna exhibits stable radiation patterns with average gain of around 3 dBi. Simulation and measurement results are in good agreement. Proposed antenna is suitable for on-demand band rejection of parasitic bands coexisting in UWB.
