Abstract
A wandered probe-fed rectangular microstrip patch antenna (RMPA) with rectangular slots on a finite ground plane with dielectric material substrate (4.4) is proposed in this paper. The proposed antenna finite ground plane dimension is only 18mm x 21mm. The simulated result shows two distinct resonant frequencies at 4.5 and 9.5 GHz. A 10-dB wide-impedance bandwidth of 1000 MHz and 4100 MHz ranging from 3.8-4.8 GHz and 5.9–10 GHz is achieved. The proposed antennas have achieved wider bandwidth (51.3%) with reasonable gain (4 dBi).
Highlights
A Microstrip patch antenna technology began in the behind 1970s [1]
After designing the conventional microstrip patch antenna, Introducing slots in the ground plane of the antenna is used for design a compact rectangular microstrip patch antenna for the C-band and X-band, which may be useful for the current miniaturized wireless communication system
The design and analysis of a novel structure using a novel technique for upper ultra wideband (5.6- 10.6 GHz) frequency range. This proposed wideband rectangular microstrip patch antenna is designed by using an introducing slot in ground plane and simulated by electromagnetic simulation software IE3D, which is based on the method of moment
Summary
A Microstrip patch antenna technology began in the behind 1970s [1]. The microstrip antenna consists of conducting patch on a lower layer separated by a dielectric substrate. Microstrip patch antenna has aroused general applications, especially in low power wireless communication [2-3]. A Microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side [1]. The radiating patch and the feed lines are usually photo etched on the dielectric substrate. By miniaturization of microstrip patch antenna, the size will open up ways of solving problems for applications [1-5]. Conventional ways of size reduction in patch antenna are a shorting pin, slots, etc. Wireless communication systems require wider bandwidth, multiband or dual band and low-profile antennas for singular applications [6-7].
