Abstract
A frequency reconfigurable design for circularly polarized antennas with conical radiation patterns is described. The design is based on a circular microstrip antenna that is operated at TM21 mode and excited by dual orthogonal feeds with a phase difference of 90°. To vary the resonant frequency of the antenna, several varactors are placed along the circumference of the circular radiating patch. According to the simulated results, it is found that the resonant frequency can be tuned from 1.55 to 2.9 GHz when the capacitance value of the varactors is decreased from 2 to 0 pF. Moreover, the antenna at each resonant frequency can provide an omnidirectional radiation pattern with good circular polarization performance and a return loss of less than 10 dB.
