In this paper a dual-band folded shorted patch antenna is designed and implemented successfully. The experimental results reveal that it has wide impedance bandwidths (SWR L and a small size of 0.25lambdaL times 0.36lambdaL. Consequently, this antenna should find applications in the modern multi...
Dual-band microstrip patch antenna with quarter-wave microstrip feed is designed. The original frequency is 2.4 GHz. The designed antenna resonates at 2.2 and 4.7 GHz. A slot is used in the middle to decrease the current flow and to reduce the VSWR, return loss. The antenna is simulated ...
A dual-band circularly polarized (CP) antenna with enhanced beamwidth is proposed in this letter. Stacked cone-patches including a small patch for upper band (1561 ± 2 MHz) and a large one for lower band (1268 ± 10 MHz) are used to achieve the dual-band operation behavior. To widen ...
