This article presents a low‐profile disk‐loaded monopole antenna specifically designed to be embedded into a manhole cover and a method to improve the bandwidth of the antenna. The antenna is placed deep inside a circular cavity formed on a manhole cover and is covered with a thick radome to protect the antenna from strong external impacts. The effect of the cavity size on the bandwidth of the antenna...
This paper presents a low profile circular patch loaded monopole antenna suitable for embedded use in a manhole cover. It consists of a center-fed circular patch and two shorting strips connecting the patch to the ground. The simulated and field test results show that the antenna embedded in a manhole cover has a good gain and omnidirectional radiation pattern on the ground surface. The antenna can...
