Design of Dual-band Circular Microstrip Patch Antenna for L-band Military Applications

Abstract

Abstract-The shorter wavelength of L-band compared to UHF permit users to adopt smaller and more cost effective antenna. A smaller size microstrip antenna is particularly attractive for military use due to greater mobility and ease of camouflage. This paper presents a dual-band circular patch microstrip antenna for L-band military applications. The proposed antenna produced a bandwidth of 1.62 -1.7GHz and 2.74 -2.8GHz. The simulated results are calculated by using lE3D software and MATLAB programming. Further, for the future work, analogous to dielectric relaxation consideration of Cole-Cole diagrams as applied to dielectric materials, a "reactive relaxation concept" will be introduced to present the frequency-dependent characteristics of the circular microstrip antenna.

A Novel Low Profile Rectangular Microstrip Patch Antenna for L-Band Applications Using High Permittivity Substrate

“…while the return loss of the proposed antenna is 21dB. So the size as well as the return loss of the proposed patch antenna in this paper are far better than [31].…”

“…The antenna fabricated for L-band application has much reduced size as compared to those available in literature [24][25][26][27][28][29][30][31].…”

Bandwidth Enhancement of Novel E-shaped Microstrip Patch Antenna with FR4 Substrate at 2.45GHz

“…So the bandwidth and gain of the microstrip patch antennas has to be improved (Nandgaonkar, Deosarkar, and Shah 2007;Rafique, Khalil, and Saif-Ur-Rehman 2017;Al-Ahmadi and Khraisat 2019)). Because of these features, Microstrip patch antennas are widely suggestable for satellite communications (Salarian and Mirshekar-Syahkal 2019), WLANs (Kurukshetra et al 2018), Missiles and telemetry (Malisuwan et al 2015), GPS systems (Nandgaonkar, Deosarkar, and Shah 2007), mobile communications (Nandgaonkar, Deosarkar, and Shah 2007;Rafique, Khalil, and Saif-Ur-Rehman 2017), etc.…”
