“…RECENTLY, microstrip grid array antennas have received considerable attention [1][2][3][4][5][6][7] because they have all the usual benefits of conventional patch type radiators plus broad bandwidth, high gain, and adequate cross polarization control. 8 Microstrip grid array antennas are usually designed to radiate fan-beam patterns with single feed for unbalanced operation 2 or with dual feeds for balanced operation.…”

The development of a dual‐feed microstrip grid array antenna for either balanced or unbalanced operation to radiate pencil‐beam patterns has been described. As an example, the dual‐feed microstrip grid array antenna on RT/duroid 5880 substrate with a size of 60 × 60 × 0.787 mm3 or 4.8λ × 4.8λ × 0.063λ at 24 GHz were designed and fabricated. The measured results show that the dual‐feed microstrip grid array antenna has achieved excellent performances: 4.85% impedance bandwidth, 9.03% gain bandwidth, and 20.6‐dBi gain at 24.15 GHz as a balanced antenna and 6.05% impedance bandwidth, 7.74% gain bandwidth, and 17.8‐dBi gain at 24.15 GHz as an unbalanced antenna. The dual‐feed microstrip grid array antenna is a suitable antenna candidate for radar and sensor applications.

“…As suggested in [9] these widths can be taken as a first approximation for the weights of the antenna elements in the array. In [10], the normalized currents, which are inversely proportional to the characteristic impedance of the radiating line, and hence approximately inversely proportional to the line width, are used as the antenna element weights. Hence, a higher current is responsible for increased radiation.…”

A wideband planar microstrip grid array antenna is presented. The antenna is realized on a standard Rogers RO3003 substrate. It is fed using two centrally located microstrip vias through a ground aperture. Measured results show a 12% S11 <-10 dB bandwidth and a maximum gain of 17 dBi. Using a variable microstrip line width, a side-lobe suppression of at least -12 dB between 77-85 GHz is measured. The antenna can be used in short and medium range operation for automotive radar.

A grid array antenna (GAA) printed on a dielectric substrate is investigated to obtain dual-beam radiation. For the analysis of the GAA, the method of moments (MoM) is applied to an integral equation expressed by Sommerfeld-type integrals. It is revealed that the maximum beam direction, gain, and half-power beam width in the principal plane are changed with frequency. The dual-beam radiation is obtained, if the operating frequency is appropriately chosen.
