In this paper we show the triangular geometry of the microstrip patch is one of the mostcommon shapes having a wide range application ranging from circuit elements to modernwireless antenna. In this paper we compare Cslot microstrip antenna an slotted equilateraltriangular microstrip antenna. Recent survey of open literature shows interesting developmentof this patch as novel ci...

This research studies the wireless strain sensing performance of a slotted patch antenna sensor. In our previous work, a folded patch antenna was designed for passive wireless strain and crack sensing. When experiencing deformation, the antenna shape changes, causing shift in electromagnetic resonance frequency of the antenna. The wireless interrogation system utilizes the principle of electrom...

In this letter, a design for broadband circularly slotted patch antenna fabricated on a singlelayered printed circuit board (PCB) with unidirectional radiation is described. It is fed by a simple center-fed feeding scheme. Unlike conventional slotted patch antennas, the proposed antenna is loaded with four short pins such that both matching and axial-ratio (AR) bandwidths are improved. In addit...

This paper presents the design, construction, and testing of a high directivity circularly polarized small patch antenna for RFID Base Stations (Readers) operating in European UHF band. The designed optimized structure has 15cm ×15 cm × 0.6 compact size where -3dB beam angle is reduced by using slotted ring embedded patch. gain at 862 MHz 3.2 dBic with E H plain are 61.6º 65.2º respectively. Fi...

In this paper, a novel multiple slot microstrip patch antenna with enhanced bandwidth is presented. The design adopts contemporary techniques namely; probe feeding, inverted patch structure and multiple slotted patch. The composite effect of integrating these techniques and by introducing the novel multiple shaped patch, offer a low profile, wide bandwidth, high gain and compact antenna element...
