An offset quad-element, two-port, high-gain, and multiband multiple-input multiple-output (MIMO) planar antenna based on a log-periodic dipole array (LPDA) for Ku/K-band wireless communications is proposed, in this paper. A single element antenna has bee
been disclosed, wherein the "inorganic metal/oxygen composition" containing thallium and at least one element selected from the group consisting of arsenic, antimony, thorium, uranium, lanthanide and elements of the groups of IIIb, IVb, Vb and VIIb of the periodic table is used in the reaction...
We denote the element zi∗[−1]∈H∗KO0 by z̄i=zi/z0, allowing us to prove: Lemma 4.1 For any element [x],[x]∘z̄i=0iff[x]∘zi=0. Proof Suppose that [x]∘z̄i=0. Then the distributive property shows[x]∘zi=[x]∘(z̄i∗[1])=([x]∘z̄i)...
A key element of any enduring legacy is the ability to adapt and evolve. In the face of technological advancements and changing market dynamics, small businesses must remain agile, embracing innovation while staying true to their roots. They must be willing to learn from their experiences, continu...
The radiating element is a slotted waveguide supporting the TE20 mode, with short-circuit terminations at each extremity. It is fed at its center by the waveguide using the TE20 mode. The radiating slots were positioned to cut current lines on metal surfaces in the same way as for a TE10...
