Abstract: Pure metallic reflectarray antennas have good power efficiency and low fabrication cost, limited to single-band operation in the past. A dual-band reflectarray antenna is developed for two ...

Abstract: This chapter introduces planar antenna design methods that can yield multiband and wideband 5G operations. It also introduces different novel techniques that combine other antenna ...

First off all, the reference design was this paper from IJRTE. This design claimed a simulation for a dual band patch antenna, with a kinda basic geometry. Only 2 slots were taken out of the regular ...

You would construct a counterpoise antenna wire 11.5 inch for VHF, 6.5 for UHF and about 19.5 inches for an OK performing dual band VHF/UHF radio. Normally with a handheld radio the counterpoise ...
