“…A low-profile 16-element printed dipole antenna (PDA) 8 × 8 units MIMO system for use in the 4.50-7.20 GHz frequency range and WLAN/WiMAX was compatible with 12 × 12 units of artificial magnetic conductor (AMC) band plates. With EBG placed at a distance of 4 mm from the antenna, a gain of 8 dBi was obtained [19]. A Dual-Band Circularly Polarized Crossed-Dipole Antenna Backed for 2.31-2.56 GHz frequency range and 5.44-6 GHz WLAN system was compatible with 5 × 6 units artificial magnetic conductor (AMC) band plates.…”

This article presents the design of a dipole antenna structure in combination with a square electromagnetic band gap (EBG) to monitor the children trapped in cars using a 750 MHz frequency band which responds the most to human movement detection. The antenna structure was designed on a copper plate with a thickness of 0.297 mm and polyester mylar film baseplate with a thickness of 0.3 mm and dielectric value of 3.2. By design, the dipole antenna had a size of 201.56 × 12.5 mm 2 and 18 × 5 units square electromagnetic band gap (EBG) of size 254.64 × 71.86 mm 2 . The results of the measurement showed that the bandwidth impedance in the operating frequency range was 4.78% (735-771 MHz) with a gain of 6.3 dBi. There was an omnidirectional signal transmission. The dipole antenna had the best distance between the EBG plates of 30 mm. When being examined at a distance of 500-1,600 mm, it was the most effective at an average signal strength of approximately 0.032 mW every time there was movement of a human body in the car.

In this study, a novel pattern shaping technique is presented and applied to the uniquely designed multiple-input multiple-output (MIMO) radio altimeter antenna, acquiring area gain. Inspired by the behavior of the perfect electric conductor, the tendency to gather a diffuse pattern is exploited to create pattern shaping. A surface with a phase response of 0° at 3.824 GHz was designed to ensure that the target radio altimeter frequency of 4.3 GHz is in the immediate vicinity of the outer phase region, where the impedance is around 166.84 Ω, transforming the diffuse pattern of the top antenna into the target conical shape. Antenna reflection values are measured as −20.072 dB at 4.344 GHz (port 1) and −27.44 dB at 4.32 GHz (port 2), while there is 6 mm between the top antenna and its reflector. At 4.32 GHz, the envelope correlation coefficient is 0.0043, the diversity gain is 9.999, and the transmission value between the opposing ports is −29.08 dB, which indicates a low mutual coupling. A MIMO antenna with a measured gain of 10.1497 dBi for port 1 and 10.5617 dBi for port 2 conforming to the design criteria of the radio altimeter is achieved.
