The Antenna Toolbox™ library of antenna elements includes a patch antenna. A dual-band CP antenna with the low axial ratio (AR), single feed and small frequency ratio (∼1.35) has been proposed in [], but the simultaneous coverage of multiple bands is still a challenge, especially at mm-wave bands. An innovative design of a monolayer, dual-band, CP slotted patch antenna (SPA) is proposed in []. The circular. The antenna consisted of an antenna patch part and a proximity-coupled feed. The antenna was fed by a proximity- coupled. The proximity-coupled was isolated from the antenna patch on the same plane. The gap between the proximity coupled and the antenna patch was 0.9 mm on its left and right sides and 0.5 mm on top.

Abstract: In this communication, the same-sense circularly polarized grid-slotted patch antenna with wide axial ratio bandwidth (ARBW) is proposed. The rectangular grid-slotted patch on top and bottom planes are excited through flipped Z-shaped slots pair using a stripline feed to generate same-sense circular polarization with wider ARBW. Handset antenna has been reported with wide bandwidth [10]. Half U-slot patch antenna with shorting wall reported in [11] with 28% impedance bandwidth. In this paper, broadband patch antenna with two square slots across its side surface is proposed. This type of Microstrip patch antenna meets the requirement of operation for wireless. The designing of an antenna with a wideband harmonic suppression will lead to enhance the overall antenna performance efficiency as well as neglecting electromagnetic noises. A “defective ground superimposing” or a Y-slot construct confederated with a ring hopefully meets an effective approach that is exploited in removing high level of harmonics in the design process.
