Miniaturized Wideband Four-Antenna Module Based on Dual-Mode PIFA for 5G 4 × 4 MIMO Applications
IEEE Transactions on Antennas and Propagation, 2021The huge proliferation of the antenna number brought by 5G greatly increases the pressure of the bezels of the 5G terminals. To release the pressure, planar four-antenna module with miniaturization and wideband performance that can be implemented on the ...

2011 International Workshop on Antenna Technology (iWAT), 2011
A conventional curl antenna is modified into a staircase curl antenna to realize a wideband axial ratio characteristic. It is found that the staircase curl has a dramatically wide bandwidth of approximately 50% for a 3 dB axial ratio criterion. It is also found that the VSWR exhibits values of less than 2 within this axial ratio bandwidth.

A Wideband Dual-Polarized Antenna for Millimeter-Wave Applications
IEEE Transactions on Antennas and Propagation, 2021A wideband dual-polarized magneto-electric (ME) dipole for millimeter waveband applications is presented. The ME dipole consists of four shorted patches, which are fed by two pairs of T-shaped probes orthogonally oriented on the same layer.

Wideband Decoupling of Integrated Slot Antenna Pairs for 5G Smartphones
IEEE Transactions on Antennas and Propagation, 2021This communication proposes a wideband decoupling technique to suppress the strong coupling between two extremely closely spaced open-slot antennas and implements a wideband integrated slot antenna pair for fifth-generation (5G) metal-rimmed smartphones.

Wideband circular polarizer for a photoconductive antenna
Optics Letters, 2023We report a thin-film circular polarizer consisting of three metal-grid layers to be used with a photoconductive antenna (PCA) to generate terahertz (THz) circularly polarized (CP) radiation. The polarizer has a high transmission with a measured 3 dB axial-ratio bandwidth of 54.7% from 0.57 to 1 THz. We further developed a generalized scattering matrix

An ultra-wideband receiving antenna array
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013An UWB impulse radio receiving antenna array based on delay and sum beamforming is presented. The array is implemented using a simple impulse radio radar transceiver. The presented radar transceiver is fabricated in 90 nm TSMC technology, and it has a high speed sampler with sampling rate of 10 GHz which recovers the received signal with sufficient ...

IEE National Conference on Antennas and Propagation, 1999
This paper describes the development of a wideband radiating element suitable for use in a planar array. The design is a more compact form of the fan dipole reported by Bailey (1984). An experimental array of such dipoles was constructed in order to evaluate the mutual coupling between the elements and the embedded radiation patterns.

Wideband substrate‐integrated monopole antenna
Microwave and Optical Technology Letters, 2016ABSTRACTA coaxial probe fed wideband low‐profile electric monopole cavity antenna with measured impedance bandwidth of 56% at a central operating frequency of 8 GHz is proposed. The antenna, based on a modified shorted square patch, effectively forms a substrate‐integrated cavity with four curved radiating slots at its periphery.
