“… will result in increasing the antenna's height approximately between 0.13λ LF and 0.15λ LF . To further improve the operating bandwidths up to 64% and 67%, the techniques of applying cavity‐backed (with sectorial loop antenna) and self‐grounded bowtie designs have also been investigated. Nonetheless, both designs need to increase the antenna's height to 0.2λ LF and 0.255λ LF , respectively, and has further required four feeding ports and has demonstrated undesirable isolation of greater than 8 dB.…”

A cavity‐backed antenna with low‐profile, dual‐polarization, and wide operating bandwidth characteristics is proposed. In this design, two orthogonally positioned triangular bowtie antennas printed on a low‐cost substrate are loaded onto a square cavity, so that two orthogonal linear polarizations can be excited. By further introducing four extended ground stubs from each side of the square cavity, the proposed antenna can also acquire low‐profile characteristic of approximately 0.1λ (15 mm). To achieve good impedance matching, additional circular slots are introduced into each bowtie design. The measured results show that the proposed antenna can cover a wide operating bandwidth of 62% (2.0–3.8 GHz) with a VSWR of 2:1. Besides exhibiting good isolation (>20 dB) between the two feeding ports, desirable realized gains (6.0–10.5 dBi) over the wide operation band are also demonstrated. © 2016 Wiley Periodicals, Inc.

“…In this section we apply (7) given above to analyze the performance of the self-grounded bowtie antenna presented in [7] for small-cell base station applications and also to a handheld device with antenna diversity (one antenna placed at the top while the other was placed at the bottom of the device's chassis). It is worthwhile to note that both antenna systems where primarily designed with the RIMP channel type in mind rather than the Random-LOS channel.…”

We derive the Multiple-Input Multiple-Output (MIMO) efficiency of the Zero-Forcing (ZF) receiver algorithm in Random Line-Of-Sight (Random-LOS). We make use of the Probability-of-Detection (PoD) curves based on the ideal digital threshold receiver model in the derivations. We show that the MIMO efficiency in this case, is mainly determined by two factors: the smallest channel gain of the two available bit streams and the non-orthogonality coefficient. This must be considered when designing antenna systems for efficient communication at higher frequencies since Random-LOS propagation will be dominating.

Abstract-The self-grounded antenna is a new type of compact ultra-wideband antennas with simple geometries. One of the characteristics of this type antenna is its high flexibility: the configuration of the antenna can be arranged in many different ways for different applications. In this paper, we overview the typical arrangements of the self-grounded antennas, and their performance for different applications.
