This section describes the design process used for implementing the 4-element antenna array for 5G sub-6 GHz MIMO applications. Also, evaluated here is the array’s performance. The reference four-element antenna array The layout of the reference antenna array is shown in Fig. 1. It is const...
weight, low profile and mass producibility are pro-vided in general by printed circuit antennas. The simplestforms of printed circuit antennas are microstrip antennaswherein flat conductive elements are spaced from a sin-gle essentially continuous ground element by a dielectricsheet of uniform thickness...

The problem of optimised design of diversely polarised sparse array for joint synthesis of spatial and polarisation beampattern is addressed in this Letter. Two kinds of polarised array configurations, cocentred and non-cocentred crossed-dipole arrays, are considered. Minimum interelement spacing constra...
A novel design solution of a dual-linearly-polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM) hybrid scanned phased array antenna appl...
spacing provides “orthogonality” that enables a receiver to recover the data from the subcarriers. In the time domain, a guard interval (e.g., cyclic prefix) may be added to each OFDM symbol to combat inter-OFDM-symbol interference. The uplink may use SC-FDMA in the form of a DFT-...
The transmit/receive element 222 may be configured to transmit signals to, or receive signals from, a base station (for example, the base station 214a) over the air interface 216. For example, in one embodiment, the transmit/receive element 222 may be an antenna configured to transmit and/...
Increasing the inter-element spacing is a technique for enhancing the directivity; however, it would bring the grating lobe into the visible zone and deteriorate the antenna radiation efficiency. The proposed technique using a supplementary sub-array would suppress the grating lobe in the visible ...
