“…The advantage of this design is that there is space left inside the ring to place another smaller element to cover the high frequency band. [6] In our case it is also a square microstrip ring. So, the antenna element consists of concentric square microstrip ring, coupled to separate small patches and ring are placed on a substrate with a dielectric permittivity of 2.95 and a thickness of 1.524 mm.…”

The design of triple -band L1/L5/S dual linear polarized microstrip antenna is simulated and presented. The triple band is designed as one antenna for dual -band L1/L5 with dual -linear polarization and a shared aperture antenna for single S band dual linear polarization behaviour. The performance of the designed antenna was compute using HFSS. The antenna is designed to fulfill the remote sensing requirements, where multi band dualrequired.

“…In order to assess the reliability of the proposed sparse plank architecture and its robustness against the non-idealities of real arrays, a square-ring microstrip antenna ( Figure 7 a), suitable for wide angle scanning [ 42 ] and resonating in the L-band, has been chosen as elementary radiator of the array. To include the mutual coupling effects of the real array structure, the whole plank model shown in Figure 7 b has been simulated at

GHz using the finite-element full-wave solver of Ansys HFSS [ 43 ].…”

The design of conical frustum phased array antennas for air traffic control (ATC) radar systems is addressed. The array architecture, which is controlled by a fully digital beam-forming (DBF) network, is composed by a set of equal vertical modules. Each module consists of a linear sparse array that generates on receive multiple instantaneous beams pointing along different directions in elevation. To reach the best trade-off between the antenna complexity (i.e., minimum number of array elements and/or radio frequency components) and radiation performance (i.e., matching a set of reference patterns), the synthesis problem is formulated in the Compressive Sampling (CS) framework. Then, the positions of the array elements and the complex excitations for generating each single beam are jointly determined through a customized version of the Bayesian CS (BCS) tool. Representative numerical results, concerned with ideal as well as real antenna models, are reported both to validate the proposed design strategy and to assess the effectiveness of the synthesized modular sparse array architecture also in comparison with conventional arrays with uniformly-spaced elements.

“…As the ring antenna has one broadside radiating mode, multiple rings have been placed concentrically to achieve multiband operation [9], [10]. Circular polarization has been achieved by placing cross-strips inside the ring [11] and by proximity coupling the antenna to a curved microstrip line [12].…”

A microstrip ring antenna has a single broadside fundamental radiating mode. In this paper one of the arms of the ring has been loaded with two stubs, so that the perturbation in the fields results in broadside radiation in the next two higher order modes. This results in three broadside radiating modes. Gap-coupled excitation is chosen to achieve impedance matching in all the three frequency bands. Linearly polarized radiation with gain of 2.88 dB, 4.67 dB and 6.07 dB and half-power beamwidth of 89.6°, 76.3° and 79° in the φ = 90° plane has been achieved at the center frequencies of 0.9526 GHz, 1.833 GHz and 2.468 GHz respectively. This structure has been analyzed using multiport network modeling. The modeling is vindicated by experimental results.
