A Low-Profile and High-isolated MIMO Antenna for 5G Mobile Terminal
Micromachines, 2020 An eight-element multiple-input multiple-output (MIMO) frame antenna array in the 3.5 GHz band (3400–3600 MHz) for 5G mobile terminal systems was presented. By using the adjacent grounding and electromagnetic coupling feeding technology, the loop antenna

Improved manual radio frequency direction finder [PDF]
, 1970 Antenna loop direction finder, consisting of two separate loops mounted rigidly together at right angles to each other, requires single rotation for operation. The loops, one for bearing, the other for sensing, are rotated manually.

UHF SATCOM broadband CP antenna: moxon type bent-dipoles over a ground plane [PDF]
, 2011 In this paper, we investigate and compare two different antenna types for UHF SATCOM applications; proposed Moxon type (bent dipole) and conventional egg beater (loop) antennas in terms of antenna performance and physical size. Bent dipole and egg beater

A revisitation of the 1888 H.Hertz experiment
, 2006 We propose a revisitation of the original experiment performed by H. Hertz in 1888. With a simple setup it is possible to produce electromagnetic waves with a frequency in the range of 3 MHz.

Fast design optimization of UWB antenna with WLAN Band-Notch [PDF]
, 2015 In this paper, a methodology for rapid design optimization of an ultra-wideband ( UWB) monopole antenna with a lower WLAN band-notch is presented. The band-notch is realized using an open loop resonator implemented in the radiation patch of the antenna ...

Electronics Letters, 1995 C-figured loop antennas are analysed numerically. The current distribution, radiation pattern and axial ratio are presented. It is found that the c-figured loop antennas radiate a circularly polarised wave with a relatively wide 3 dB axial ratio bandwidth ( approximately 5%). >

Broadband Dual-Polarized Multidipole Antenna for Base Station Applications
International Journal of Antennas and Propagation, 2021 A wideband dual-polarized multidipole antenna for base station applications is proposed. It consists of a pair of large square-shaped loop dipoles and a pair of small rectangle loop dipoles as radiation elements. A pair of small rectangle loop dipoles is
