In this paper, a technical review on gap-coupled microstrip antennas is presented. The gap-coupled microstrip antennas give a large bandwidth as compared to the conventional microstrip antennas. The method of bandwidth enhancement using gap-coupled microstrip antennas has been elaborated. The gap-coupled microstrip antennas also produce two resonances. The dual frequency operation of the gap-coupled microstrip antenna is also described. A research overview of gap-coupled microstrip antennas, challenges, types of gap-coupled microstrip antennas as well as numerical methods of calculating various parameters of the gap-coupled microstrip antennas are discussed in this paper.

“…Array antennas have been extensively used in millimeterwave (MMW) technologies because of their capability to radiate highly directional patterns owing to specific array arrangements [1,2,3]. Generally, to reduce clutter interference, low first side-lobe level (FSLL) and low front-to-back ratio (FBR) are expected in antenna design [4]. In addition, their low profile characteristics and light weight meet application requirements [5,6].…”

This study proposes a Ka-band high-performance microstrip array antenna having a planar array front-end and strip-line back-end. 10 × 4 hybrid-fed rectangular patches with Taylor-synthesized excitation is adopted to form weighted patterns. Preferable symmetrical patterns are obtained covering 34.5-35.5 GHz working band due to the symmetric feeding arrangement. The measured reflection coefficient is lower than −10 dB, and peak co-polarization gain and first side-lobe level are better than 19 dB and −17 dB, respectively. Additionally, the strip-line back-end ensures an ideal front-to-back ratio of approximately 40 dB. The measurement results coincide with the simulation results, proving the immense prospect of our design in airspace detection or other applicable scenarios.

“…Increasing bandwidths and gain has always been an important issue in antenna engineering, which has derived development of a frequency selective surface (FSS) technique used for a partially reflective surface (PRS) or a Fabry-Perot cavity (FPC) in various applications [1,2,3,4,5,6,7]. Although many antennas adopting PRSs or FPCs can provide high gain, their impedance matching bandwidths are still very narrow, and overall antenna performance is highly dependent on frequencies.…”

A new method for tilted radiation using frequency selective reflectors

We propose a new beam control method using frequency selective side reflectors (FSRs) with no help of the conventional array of multiple antennas. To control radiation directions on an H plane, we need only one feeding dipole antenna with a pair of the FSRs placed on both sides of the dipole antenna. Each FSR consists of equal-length rectangular copper patches. But, in order to obtain different reflection phase from each FSR, the lengths of the patches on each FSR are different from one another. By changing reflection behavior of each FSR, we can derive constructive interference between a direct wave from the dipole and the reflected waves from the FRS and a ground plane. Consequently, we can direct our antenna beam in any target direction with relatively high gain in a wide frequency range.
