Quarter-wave (Monopole) Antenna Radiation Pattern The impedance of the quarter-wave antenna is 36 Ohms, which is half the impedance of a dipole antenna. Unlike a dipole antenna, a monopole antenna is single ended, which is convenient for interfacing with a single-ended transceiver. This ...

This letter presents a specific design of an ultra-wideband (UWB) microstrip monopole antenna of dimensions 35 × 25 × 1.6 mm realised on FR4 substrate. The UWB performance from 3.1 to 16.3 GHz is achieved with return-loss better than 10 dB. To achieve UWB performance, a quarter circular ...
Antenna measurements,Wavelength measurement,Resonant frequency,Reflector antennas,Broadband antennas,Wideband,Long Term EvolutionA compact hybrid wideband antenna with a quarter-mode cavity and a monopole is proposed for low-cost LTE base station application. The proposed design is very simple. The ...
This antenna is designed and optimized by using full-wave simulation software and is continuously reconfigurable over a frequency range of 380 MHz which is from 2.33 GHz to 2.71 GHz. Also, the vertically-polarized monopole-like radiation pattern is kept within the frequency range.Huan Qian Xiong...
The proposed antenna operates as a 4 × 4 multi-input multi-output (MIMO) system in three 5G/6G millimeter-wave (MMw) bands, while functioning as a single element antenna for a 5.5 GHz wireless fidelity Microwave (Mw) band. The antenna comprises four QMSIW cavity resonators; each QMSIW ...
