Abstract: This letter presents a new low-profile, reconfigurable pattern antenna. The antenna features a printed circular segmented loop fed by two separate feed points coupled to a parasitic ...
Abstract: This paper theoretically investigates a quartering circular loop antenna composed of four identical arc elements with independent feed sources, operating in ionospheric plasmas at very low ...
