In this paper, the performance of loop antenna placed at a specified distance and parallel to the ground plane is assessed through simulation for usage in fresh water and operating in the High Frequency (HF) band. Three variations of this antenna namely; the circular loop, the square loop ...
Loop antennas are great for situations where space is an issue or when one has interference that is from a point source that needs to be mulled out.Passive loops are no substitute for a full size resonant antenna. Reply #13 on:January 20, 2016, 06:29:05 pm » Sue, what kind of ca...
19. The loop antenna of Claim 1 wherein a first one of said radiation loops is on one layer mounted on a dielectric material and where a conductive region is on a different layer mounted on said dielectric material juxtaposed said first one of said radiation loops. 20. The loop antenna ...
HF In Small Spaces February 3, 2024byBryan Cockfield22 Comments Generally, the biggest problem a new ham radio operator will come across when starting out on the high frequency (HF) bands is finding physical space for the antennas. For a quick example, a dipole antenna for the 20 m band...
According to the theory of sea echoes,this paper studies the application of crossed-loop/monopole antenna in ocean surface current detection by HF ground wave redar. 针对高频地波雷达天线阵通常十分庞大的问题,根据海洋回波理论,利用单个到达角海洋回波进行雷达通道幅度相位的自校准,应用适合便携式天线系统的...
station as well as the HF vehicular communication devices. The antenna adopts the techniques of the magnetic loop antenna, which makes the inner small loop coupled and excited the large loop outside by power feed of the small loop. On the condition of resonance, the large loop could radiate ...
I am currently comparing it with a larger loop antenna inside the car to see how they differ. In fact, all of my antennas—whether for VHF/UHF or CB—are installed inside the passenger compartment of my car, and I can assure you, they work very well. Even my antennas for HF listening...
