Overview

A gap antenna is composed of a resonant cavity and a protective cover. The rectangular resonant cavity has several slots on its wide side, and the number of slots determines the gain of the antenna. The distance between the two layers of gaps in the axial direction is about one wavelength, and the length of each gap is also nearly one wavelength. Theoretical calculations are based on one wavelength. The feeding of each slot is coupled by inductance or capacitance, and the maximum gain of the antenna is obtained by adjusting the balance of the resonance amplitude of each slot.
The feeding system of the slot antenna is accommodated inside the antenna cavity, so the feeding joints of the antenna are few, the feeding is compact, miniaturized, and the feeding loss is low. In addition, the feeding system is completely sealed inside the antenna cover, so the antenna has the characteristics of compactness, strong sealing, and high stability.

Features

1)The antenna adopts multi-channel transmission technology, which has higher gain and more uniform horizontal radiation field pattern
Long operating distance, uniform field strength coverage, and low standing wave ratio.
2)The antenna cavity is made of high gloss aluminum plate, the antenna feeding system is all silver plated, and the antenna cover is made of high-strength and low loss glass fiber material.
3)High stability, low feed loss, and strong corrosion resistance.
