In this paper, the simulation of three monopole with G type structure is proposed consisting of one closed rectangular wire loop and one open rectangular wire loop with maximum horizontal and vertical dimensions approximately of L1 = L2 = L3 =.25lambda, h=202lambda, w = .1834lambda, l =.3487lambda and having wire radius of 2 mm. Each of the structure is analyzed on perfect ground and on CUBESAT and...
In this paper, the high gain electrically small loop antenna which is satisfied with the small antenna condition ka <1 and MNG MTM condition kreles0.5 is proposed. The proposed antenna is designed with the MNG MTM ground structure in order to match a high inductive reactance. Although it has a compact size, the high efficiency and gain are achieved. It will be available to apply to mobile UMTS...
In automatic meter reading (AMR) systems, one embodiment of the prior art comprises: the PCB, the battery and the antenna are held together in a short plastic tube and encapsulated. The antenna and the unit is then put into a metal walled, metal or plastic covered pit, where the antenna part is at the level of the ground plane and slightly lift above the plastic or metal cover through a hole in the...
