Design of a Compact Dual Band Microstrip Antenna for Ku-Band Applications

Abstract

A new design of dual band compact microstrip antenna is proposed for Ku-band applications.Dual band is achieved using three pairs of thin slits from the sides of a rectangular patch and feeding with a microstrip feed line.The result shows that a return loss of -32.9dB is achieved at the first resonant frequency of 12.72GHz, and -14.4dB is obtained at the second resonant frequency of 14.4GHz frequency with VSWR ≤ 2indicating improved matching conditions. The results ofsimulation are return loss, radiation pattern, VSWR, and band widtharepresented. The design is performed by using Ready-madeSoftware package Zeland-IE3D. The antenna is fabricated using thin film and photolithographic technique and measured using the Vector Network Analyzer. The final result shows that good agreement between the simulated and measured results.

Single‐layer single‐patch dual band antenna for satellite applications

“…In [9], substrate with dielectric constant of 3.5 and height of 1.5 mm is used but the size of the antenna is 50 mm × 50 mm which is very large compared with the size of the proposed antenna. In [23,34], substrate of dielectric constant of 10.2 is used which is quite high as compared with the substrate dielectric constant of the proposed design. The substrate used in the proposed design is cheapest among all designs listed in Table 2.…”

“…For dual/wide band requirement, many antennas have been investigated and proposed in literature [1][2][3]. Similarly several patch antennas have been reported in literature for satellite application in Ku-band, such as slot loaded patch with coaxial feed [4][5][6][7], E-shaped patch antenna [8], microstrip feed spidron fractal patch antenna [9], multi layered truncated corner square-ring slot [10], aperture coupled ring slot with cross [11], multi-layer rectangle patch antenna array [12][13][14][15], proximity-coupled multilayer truncated corner antenna [16], proximity coupled feed spidron fractal slot antenna [17], aperture coupled antenna array [18], microstrip feed with patch sharing technique [19], multilayered and parasitic patch antenna [20], hybrid microstrip and waveguide feed antenna array [21], microstrip feed slotted antenna [22][23][24], stacked patch antenna [25,26], orthogonal feed patch antenna [27], aperture coupled stacked patch antenna array [28], slot antenna with DGS [29,30], SIW integrated antenna array [31], coaxial feed circular slot polygonal antenna [32], microstrip feed patch antenna with additional resonator [33], and cross shaped microstrip feed patch antenna [34].…”

Compact Tri-Band Patch Antenna for Ku Band Applications

“…In the literature, many antennas have been proposed to fulfill the requirement of multiband applications [1][2][3]. A lot of patch antennas have been designed for Ku-band satellite applications such as dual-band antenna with single-layer and singlepatch for Ku-band satellite application, low profile patch antenna, and loaded slot patch antenna for applications in Ku-band [4][5][6][7][8][9][10].…”

5G MIMO Conformal Microstrip Antenna Design

“…The microstrip antenna has many advantages such as low profile, small size, light weight, and ease to integrate with other carriers. It is therefore more suitable for conformal antenna [12,13]. In addition, the millimeter-wave band has attracted a lot of attention due to the advent of 5G technology and its inherent characteristics, such as short wavelength, wide frequency band, and propagation characteristics in the fog, snow, and dust environment [14][15][16].…”
