The objective of this paper is to provide the context, physical insight, and perspective on
antennas in wireless communications. Although it does not mean to be comprehensive, the …

Both the radiation efficiency and bandwidth of electrically small antennas are dramatically
reduced as the size decreases. Fundamental limitations on the bandwidth of small antennas …

A compact, fully-printed negative-refractive-index transmission-line (NRI-TL) metamaterial-
loaded dipole antenna is proposed, which exhibits multiband resonant characteristics that …

A two-dimensional (2-D) resonant-type composite right/left-handed transmission line (CRLH
TL) is proposed consisting of complementary split-ring resonators (CSRRs) and series …

The theory and design of a new family of multifrequency monopole antennas by smartly
loading a set of complementary metamaterial transmission line (CMTL) unit cells are …

A compact multi-band printed dipole antenna loaded with reactive elements is proposed.
The reactive loading of the dipole is inspired by the Epsilon–negative (ENG) and double …

This letter presents a passive UHF printed loop antenna with left-handed loading. The RFID
reader antenna can work at near-and far-field operation within the European UHF (865-868 …

In this letter, the use of artificial magnetic conductor (AMC) to load a monopole antenna has
been investigated. It is known that the current reversal, which occurs at frequencies much …

The conventional series-fed endfire dipole antenna has a wide impedance bandwidth and is
inexpensive to manufacture. However, it has a disadvantage: its size is large because of the …

This paper presents the successful design and physical realization of a wideband MNG-TL
dipole antenna. An artificial mu-negative transmission line (MNG-TL) structure is realized by …
