A simple, planar, low-profile and wideband optical transparent end-fire magnetoelectric (ME) dipole antenna array is presented in this article. The metal mesh printing on the glass substrate uses a conductive silver grid layer. The top layer has electric and magnetic dipoles with the coplanar ground. An Γ-shaped transmission line is used to feed the ME dipole antenna and printed on the bottom layer. Good radiation performance of single antenna element, including an impedance bandwidth of 24.9%, average gain of 8 dBi, radiation efficiency of over 80%, and end-fire radiation patterns at 28 GHz band, are also achieved. Furthermore, a 1 Â 4 transparent end-fire ME-dipole antenna array is realized by employing the proposed ME-dipole single antenna element. A prototype was fabricated by in-house photolithography and lift-off process, which is measured to confirm the simulation results. Measured impedance bandwidth is 33% from 23.3 to 32.5 GHz (VSWR ≤ 2). End-fire radiation patterns are obtained across the entire bandwidth with a peak gain and radiation efficiency of 13.6 dBi and 80%, respectively. The optical transparency is around 66% across the visible spectrum.

“…The problems of these transparent materials, however, are their cost, high surface resistance, and scarcity [13]. Another method used for transparent antennas is the usage of metal mesh grid, which has high conductivity and low resistance compared to transparent conductive oxides [12], [14]. As a result, mesh grid method is more preferred and investigated in recent years [15], [16].…”

In this paper, a single-layer one-sided wideband coplanar waveguide (CPW)-fed transparent circularly polarized (CP) rectangular slot antenna with tilted beam is proposed. The antenna is designed on a glass substrate with a mesh grid in the conductive layer in order to increase the transparency. Since most of the vehicles' windshields are inclined for about 30 degrees, the beam of the antenna is designed to be tilted for about 30 degrees in elevation. For measurement verification, an inclined stage is fabricated to resemble the inclined surfaces (such as the windshields). The 10-dB impedance bandwidth of the antenna is 40.8% (1.13 -1.71 GHz) with a 3-dB axial ratio bandwidth of 47.4% (1.06 -1.72 GHz) and a 3-dB gain bandwidth of about 54% (1.02 -1.78 GHz ) with a maximum right handed circular polarization (RHCP) gain of 5.3 dBic. Also, the transparency of the antenna is about 95%. Therefore, the antenna is a good candidate for vehicular applications such as location tracking, using global navigation satellite system (GNSS) and specifically global positioning systems (GPS). Furthermore, a small-size transparent reflector is designed to be used below the proposed antenna in order to increase the front to back ratio (FBR).INDEX TERMS characteristic mode analysis (CMA), circularly polarized (CP) antenna, global navigation satellite system (GNSS), global positioning systems (GPS), slot antenna, tilted beam, transparent antenna, vehicular applications

“…Zinc Oxide is still under research and it is not available commercially giving Silver Tin Oxide an advantage for its use in the field of antennas. Transparency achieved by the use of conductive oxides gives these antennas an upper hand over other conventional nontransparent antennas where such antennas can be widely used for applications like RF energy harvesting, green buildings, solar panels of satellites, defense, and automobiles . Conductivity of AgHT ranges from 250 000 to 125 000 Siemens/m for its two variants AgHT‐4 and AgHT‐8.…”

A dual‐band optically transparent antenna based on a slotted interconnected ring resonator as an efficient radiating element is proposed. The compact radiating element and partial ground plane are structured on a plexiglass substrate with Silver Tin Oxide as transparent conducting material. The radiation disadvantage of OTAs due to the low conductivity of conductive oxides has been overcome with the gain improvement technique of 2 × 1 antenna array design. The overall sizes of the proposed single element and 2 × 1 two element array antennas are λ/2.5 × λ/2.5 and λ/1.19 × λ/2.08 at the lower resonance frequency of 2.4 GHz, respectively. The operation bands of both OTA prototypes cover WLAN and WiMAX frequency bands with permissible bandwidth and sufficient gain therefore the 2 × 1 antenna array is utilized as one of two dual‐band antennas of a 2 × 2 MIMO transceiver system for WLAN and WiMAX band operations.
