“…The input impedance of the outlying corner-fed patches can be estimated through the closed form expression derived in [6], and the relevant loading effect can then be included in the design and impedance matching of the central patch by using the method of moments (MoM) [7] in conjunction with basic circuit theory [3].

“…The excitation amplitude for the outlying patches is controlled by the impedance levels of these elements and the central patch, while the excitation phase is made equal to that of the central patch by tailoring each connecting microstrip line to be one-wavelength long on the whole. The input impedance of the outlying corner-fed patches can be estimated through the closed form expression derived in [6], and the relevant loading effect can then be included in the design and impedance matching of the central patch by using the method of moments (MoM) [7] in conjunction with basic circuit theory [3]. It is pointed out that the central patch turns out to be smaller than the external ones due to the loading of the surrounding elements and aperture coupling, which tend to decrease its resonance frequency.…”

A novel planar polarization‐agile microstrip subarray is proposed and its performance assessed by a thorough numerical investigation. The subarray consists of five square patches with a central element, directly coupled to a pair of microstrip feed lines by a cross‐shaped aperture, which spreads the power outwards to the other patches through a network of suitable connections. By properly exciting the antenna at its input ports, any kind of polarization of the radiated field can be accomplished with fairly low cross‐polarization levels. Moreover, since only two feed lines are required to drive the whole subarray, polarization agility is simply and attractively achieved by a single phase‐shift circuit. The design concept is described and the results of the analyses and simulations performed by two completely independent full‐wave approaches are presented and discussed.

“…Cruz and Daniel [2] presented an experimental analysis of the corner-fed square patch element. A closed-form expression for the input impedance of a corner-fed patch antenna was reported by Lim et al [3]. Many microstrip arrays of these elements have been developed for various demands, such as low side-lobe, shaped beam, multibeam, etc [4][5][6].…”

A low-cost Ku-band array of microstrip antennas, which is fed by standard waveguide, is presented in this article. The 72 corner-fed square patches of the array are arranged in a 6-by-12 configuration. A novel waveguide-to-microstrip transition with power divider is employed as the fed for the array to reduce the loss of the microstrip feed line. The resonant frequency of the array is 12.5 GHz and the gain was measured to be 24.3 dBi. The measurement results show good agreements with full-wave simulation. This array of waveguide-fed microstrip antennas can be used in many modern communication systems, such as a mobile radar sensor, in which the transition can be fixed as a connection between the module with a front-end waveguide and the antennas.

A low-cost, low side-lob Ku-band array of microstrip antennas, which is fed by waveguide, is presented in this paper. The 72 corner-fed square patches of the array are arranged in a 6-by-12 configuration. A novel waveguide to microstrip line transition with power divider is employed as a centre fed for the array in order to reduce the loss of the microstrip feed line. The gain of the array was measured to be 24.1 dB. The side-lob is below -20 dB and the return loss at resonant frequency is less than -25 dB. This array of waveguide-fed microstrip antennas can be used in many modern communication systems, such as a mobile radar sensor, in which the transition can be fixed as a connection between the module with a front-end waveguide and antennas.
