Abstract A novel dual-band rectangular slot antenna is presented for dual-sense reconfigurable polarization. A W-shaped microstrip feedline and two rectangular parasitic patches are used to obtain dual-band circular polarization. Further, the feedline is modified so that the senses of polarization at the two bands are opposite. By introducing PIN-diodes in the feed lines, polarization can be switched among left-hand circular polarization (LHCP), right-hand circular polarization (RHCP), and linear polarization (LP). A prototype dual-band dual-sense antenna with f01 = 1.9 GHz and f02 = 3.45 GHz is fabricated in a 1.6 mm thick FR4 substrate. The measured circular polarized bandwidths are more than 7.6 % for the lower band and 5 % for the upper band.

Simulation Results

Patch antennas with a meandering slot and different distributions of grounded metallic vias are presented in this paper. The meandering slot is adopted to stimulate dual-band operation, while the number and position of the grounded metallic vias are suggested to achieve different radiation performances. The characteristics are analyzed in detail where we find that the existence of the vias also improves the impedance matching. Four samples are designed, where dual-band with both linear polarization, dual-band with circular- and linear-polarization, and single band with linear polarization are obtained, respectively. The samples are finally fabricated and the measurement results agree well with the simulation results.

Circular Patch Antenna

In this communication, a circular patch antenna is reported for dual- band operation based on VIAs. Initially the patch is resonating at single band with Linear Polarization (LP), and the Circular Polarization (CP) is obtained by inserting semi circular cuts at the edges of circular patch. The second band is achieved by loading the vertical metallic VIAs along the circumference of the patch antenna. The reported antenna is working at 2.4 GHz (Wi-Fi) and 3.5 GHz (5G) bands with Return Loss Band Width (RLBW) of 4.83% and 10.37% respectively. The Axial Ratio (AR) bandwidth at 5G band is 2.38% (3.31- 3.39 GHz)
