Dual-band slotted microstrip patch antenna design for application in microwave communication

Abstract

A single layer, single feed compact slotted patch antenna suitable for dual-band operations is thoroughly simulated in this paper. Patch antenna is basically a low cost, light weight, medium gain and narrowband antenna and suited for short-range microwave application such as a feeding element for other antennas and in research institutes as a reference antenna, it can also be used at output of signal conducting circuit for receiving signals from MEMS. By loading properly arranged slots on a rectangular microstrip patch, dual frequency and broadband operations of a single feed rectangular patch is achieved to increase bandwidth performance of the antenna. The impedance bandwidths of 562.85 MHz with return loss -28.64 dB and 1.17 GHz with return loss -43.40 dB are obtained in the proposed design. And simulated antenna size has been reduced by 59.07% with an increased frequency ratio when compared to a conventional microstrip patch antenna. The characteristics of the designed structure are investigated by using MoM based electromagnetic solver, IE3D. The simple configuration and low profile nature of the proposed antenna leads to easy fabrication and make it suitable for the applications in microwave communication system.

Multiband Circularly Polarised Microstrip Patch Antenna With Minkowski Fractal Slot for Wireless Communications

“…In microstrip patch antennas radiating elements and feed lines are usually photoetched on dielectric substrates [1]. Slot-loaded patch antennas are found in various works for dualband operations [2][3][4]. Multiple slits made on a rectangular patch are used for multiband operation in [5].…”

Design of an UWB (2.1–38.6 GHz) circular microstrip antenna

“…Majority of printed‐circuit UWB antenna designs reported in the 3–10 GHz region and rarely any design exists to cover higher frequencies such as 3–40 GHz band with potential applications in the medical, vehicular radar band (22–29 GHz), or through‐wall imaging systems . Air bone intercept, radar, missile guidance, and short range tracking system utilizes X band (8–12 GHz), while Ku band (12–18 GHz) is used for high resolution mapping and tracking the satellite within the ranges roughly from 12.87 GHz to 14.43 . Electronic warfare systems utilize an UWB antenna to scan and locate a large volume of enemy area over a continuous large unknown frequency spectrum .…”
