This paper presents the performance analysis of a LTE (Long Term Evaluation) band microstrip antenna printed on FR-4 substrate material. FR-4 substrate is a composite material of fiberglass cloth with flame resistive epoxy resin binder. It is a popular candidate for material selection in antenna design at higher bands. The proposed antenna contains a rectangular slot on the patch and covers the LTE band 7 (2.5 - 2.7 GHz). It is a cost effective approach to fabricate microstrip antenna for the LTE band 7 which is used in LTE technology throughout the world. The result shows a coverage bandwidth (<-6 dB) from 2.47 GHz – to 2.75 GHz and at 2.6 GHz the maximum achieved gain is 5.2 dB. The S-parameter is used as a comparison matrix for the simulated and fabricated antennas.

Abstract In this paper, a stacked microstrip patch antenna with polarization reconfigurable property has been proposed for worldwide interoperability for microwave access (WiMAX) application. The proposed antenna has two substrate layers: upper and lower layers with two radiating patches connected with the coaxial probe. Without the upper layer the lower square-shaped substrate layer having regular hexagonal radiating patch with probe fed acts as a linear polarized antenna with impedance bandwidth for (S11 ≤ −10 dB) is 370 MHz 10.56% (3.32–3.69 GHz) cover WiMAX (3.4–3.69 GHz) application band. The hexagonal radiating patch is perturbed with an optimum rectangular slot to enhance the impedance bandwidth of the antenna. The lower substrate layer having hexagonal patch with the same probe position is stacked with the upper square-shaped substrate layer with same sized square patch and the upper patch soldered with the coaxial probe. The overall stacked antenna generates a circularly polarized band when the opposite corner of the top square radiating patch of the upper layer is truncated with optimum size. In order to generate another circularly polarized band and to improve the input impedance matching of the stacked antenna, the top radiating patch is perturbed with two slots and a slit. The stacked circularly polarized antenna generates impedance bandwidth of 12.75% (3.23–3.67 GHz) for (S11 ≤ −10 dB) with two circularly polarized bands (3.34–3.37 GHz) and (3.66–3.70 GHz) as per (axial ratio ≤ 3 dB) for WiMAX application. Therefore, the proposed antenna can be used as linearly polarized or dual band circularly polarized according to requirement.

In this paper, a novel wideband circularly polarized (CP) millimeter wave (mmWave) microstrip antenna is presented. The proposed antenna consists of a central patch and a microstrip line radiator. The CP radiation is achieved by loading a rectangular slot on the ground plane. To improve the 3-dB axial ratio bandwidth (ARBW), two symmetric parasitic rectangular patches paralleled to a central patch and a slit positioned to the right of the central patch are loaded. To verify this design, the proposed antenna is fabricated with a small antenna of 2.88 × 3.32 × 0.508 mm3. The measured impedance bandwidth (IMBW) for S11<−10 dB of the proposed antenna is 35.97% (22.8 to 33.8 GHz). Meanwhile, the simulation result shows that the 3-dB ARBW is 15.19% (28.77 to 33.5 GHz) within impedance bandwidth, and the peak gain is from 5.08 to 5.22 dBic within 3-dB ARBW. The proposed antenna is suitable for CP applications in the Ka-band.

This article presents a bandwidth enhancing technique using a modified ground plane with diagonal edges, rectangular slot, and T-shape cut for the design of compact antennas. The proposed low-cost, compact-size circular patch antenna on 3 cm 5.1 cm printed circuit board (FR-4) is designed and validated through simulations and experiments. Results show that the T-shaped ground plane with the presence of the diagonal cuts at the top corners and the rectangular slots can increase the bandwidth. Return losses of 19 and 26 dB for the first and second resonant frequencies, respectively, can be achieved when the depth of the diagonal cut is 5 mm, the dimension of each rectangular slot is  mm, and the T-shaped size is  mm, providing a 28.67% wider bandwidth than FCC standard.

Microstrip patch antenna is a compact antenna which suffers the limitations of poor gain and reduction in radiation pattern. To reduce the resonance frequency of microstrip antenna increases the length of surface current with help of cutting slots in the patch. In this paper, a comparison of four Microstrip antennas with unequal length of rectangular slots is proposed. The microstrip antennas having rectangular shaped ground plane and FR4-epoxy substrate with relative permittivity 4.4, relative permeability 1 and dielectric loss tangent 0.02 with an overall size of 100×100×5 mm3. The performance of antennas is compared with slots in the patch and the effects of rectangular slots using operating frequency of 8 to 12 GHz are presented. The design simulate and analyze on FEM based HFSSv11 and this helps to compute VSWR, return loss,  gain, radiation efficiency and 3D polar plot of the proposed microstrip antenna. The proposed configuration gives broadside gain of more than 8 dBi and VSWR (>2) over entire range in simulated results.
