A compact multiband monopole antenna with a defected ground plane
(2008)A compact multiband antenna is proposed that consists of a printed circular disc monopole antenna with an L-shaped slot cut out of the ground, forming a defected ground plane. Analysis of the current distribution on the ...

A Directivity-Band-Dependent Triple-Band and Wideband Dual-Polarized Monopole Antenna Loaded with a Via-Free CRLH Unit Cell
(2015)A printed triple-band and wideband dual-polarized meander-line monopole antenna with a single CRLH metamaterial loading is presented. The metamaterial loading improves the impedance matching and causes the proposed antenna ...

A miniaturized multiband monopole antenna using a double-tuned wheeler matching network
(2010)In the reception and transmission of radio signals it is often required to match an antenna to its feed line over a wide frequency band. In order to achieve this, many techniques have been proposed which address the ...

Planar antennas for compact multiband transceivers using a microstrip feedline and multiple open-ended ground slots
(2015)Two planar antennas for compact multiband transceivers are presented, that employ an open-ended microstrip feedline that couples to multiple open-ended ground slots. The effect of separately introducing each of the slots ...
